Special feature of 1905 film network The online drama "Under the Alien", starring, recently ended. Among them, the participation of digital actor Lili has attracted everyone’s attention.

In recent years, with the continuous development of AI technology, digital actors frequently appear in film and television works, so what is the audience’s acceptance? Will digital actors take away the jobs of real actors in the future? ""brings exclusive observation.

In Under the Alien, digital actor Li Li plays a role of losing limbs and showing his power through electromagnetic wave wandering — — "two strong". Through AI technology, the actions and subtle expressions needed by the role are realized.

Dai Qing, a professor at Communication University of China, believes that "Erzhuang is the center of digital integration, and the role setting is more suitable for this figure. I think the appearance is too perfect, and her personalization may be a little weak. "

In recent years, digital actors created through AI technology have gradually entered the audience’s field of vision.

In the TV series "20 Don’t Confuse 2", the digital actor 202 performs in the form of combining with equipment. The digital actor Ji Feng based on the image of the actor and the virtual idol Chun Cao made by film technology are also exerting their strength in the fields of film and television and games.

Cai Juntao, CEO of WeiHaiCan Entertainment, said that in the future, Chuncao, a digital person, will be operated as a real artist, allowing her to perform movies, sing songs and record variety shows.

It is understood that the digital mile created by AI technology reduces the cost and time invested in modeling, original painting and other links, and also avoids the dependence on moving capture technology, which reduces the production cost by 80% and improves the efficiency by 40%. Efficiency and convenience are the important reasons why producers admire digital actors.

Guo Jianjun, founder of the C-TREK era, said, "AI is an improvement of productivity for us. We hope that it is also a liberation of productivity. I hope that AI will appear more and more in our works in the future."

On the other hand, digital actors can also fill the gap of real actors.

"When we have appeals to an actor, we especially like him, like his sunshine, like his strong body muscles, and like all kinds of him, but it is a pity that he has a little melancholy eyes to some extent, which is even more touching. There are very few such actors in life, and they have done it in AI. I saw an experiment they did, and it was perfect." The director shared.

The arrival of digital actors also shocked the actors.

"() showed me a video, about 30 seconds. He is an old man, in an indoor environment, the lights are dim, and he is talking lines inside, and his expression is a little sad. Director Frant Gwo asked me, What do you think of his performance? I said it was good. It was quite distracting. Then he told me that this was a performance made by AI. Teacher Frant Gwo looked at me proudly and said, Songwen, this is the challenge of the future. I felt a little depressed. I’m thinking that AI may be perfect, but we humans have become more real because of our own defects, which may be exactly what AI technology can’t do. Performance should be to interpret the truth in life we have seen. "

Faced with the threat posed by digital actors, many people are as optimistic as Zhang Songwen.

Simon, an actor, said, "With the progress of science and technology, there is no way to stop the wheel of this era. I still have food so far, and he won’t take over my job. " The actor said, "Now the technical development of expression has been very advanced. Looking closely at Chuncao’s expression is really lifelike, and I look forward to working with her." The director said, "AI’s character image certainly can’t replace the actor’s real, warm, personal experience and full of agility."

At present, digital actors are still in their infancy, and there is still a broad space for technological development, and they are also facing problems such as high production cost and insufficient production capacity. However, many people in the industry are still very optimistic about the development prospects of digital actors in the film and television industry.

"In the future, there will be more AI performances and various forms of artistic expression, but it will definitely take a period of accumulation, because it requires too many technical achievements, including the level of performance, the subtlety of movements, and more realistic voices and dubbing." Dai Qing pointed out.

In July this year, in Hollywood, actors and screenwriters faced the threat of being replaced by AI and staged an unprecedented strike. Domestic filmmakers also hope to standardize and guide the healthy development of AI technology and digital actors.

Yin Li believes that "the use of this virtual actor in AI technology will also involve digital version, portrait rights and other issues that have not appeared before", and Huang Jianxin believes that "now all countries in the world are legislating to stipulate the progress speed of AI, so as to solve the relationship between people and AI system. If it is just a tool for you, countries will definitely not legislate, so we are facing a huge challenge. "

　　Xinhua News Agency, Taiyuan, August 2nd (Reporter Liu Xiangxiao, Ma Xiaoyuan) "One end is connected with the classroom, and the other end is connected with the vast nature and society" … … With the coming of summer, various summer camps and research activities have appeared one by one, which has become an important choice for many parents to solve the problem of summer children’s custody, let their children increase their knowledge and exercise. However, the reporter learned that behind the hot market, some summer camps have questionable qualifications of teachers, the teacher-student ratio is too small, and there are loopholes in management. Some institutions have "overlord" contracts, which brings hidden dangers to the safety of participating in the camp and consumer rights protection.

　　The qualifications of teachers in the camp are worrying, and the teacher-student ratio is evasive.

　　A week ago, Mr. Wang, a parent of Shijiazhuang, Hebei Province, wanted to enroll his daughter in a summer camp. A summer camp institution named "XXX Business School" attracted his attention. "I have browsed seven or eight products in a row on this institution’s WeChat WeChat official account and found that they are all full. I didn’t expect it to be so hot."

　　The reporter learned from the online travel platform "Where to Go" that China’s research travel market has recovered rapidly this year. In the first half of this year, the number of research travel orders on this platform has exceeded 70% in the same period of 2019, and the bookings of some popular projects even exceeded the same period of 2019.

　　"From the platform data, more than 80% of family travel users will search for research-related tourism products. Before the epidemic, there were many research products in 7 -10 days’ long-term summer camps, and now the short-term research products in 3 -5 days are more popular with parents. From the price point of view, the per capita cost of summer study summer camp is in 600 yuan -1000 yuan every day, which has considerable advantages in the hot summer tourism market. " "Where are you going?" said Song Yawen, Marketing Director of Holiday Division.

　　Different from ordinary travel, parents pay more attention to the growth of children’s knowledge, the broadening of their horizons and the improvement of their comprehensive ability when choosing summer camps, and the management and safety of summer camp activities are also very important. However, the reporter found that compared with the organizers who spared no effort to publicize many benefits and advantages of summer camp, keywords such as teacher-student ratio and personnel access qualification were too "low-key" in their publicity.

　　Not long ago, Ms. Li, a parent of Taiyuan, Shanxi, was carefully selected and enrolled her daughter in an "English" summer camp. The organizer of the camp came from Beijing, claiming that the team was very professional and the participation in the camp was expensive, so Ms. Li gave her daughter to the other party with confidence, but what happened afterwards made her unexpected.

　　"Teachers are very laissez-faire about dormitory management. Some children are young and have weak living ability. Teachers don’t give guidance at all, and even don’t come forward to coordinate when they encounter bullying." Ms. Li questioned whether the camp teachers have any selection criteria, whether they need to have certain qualifications, whether they have done pre-job training, and whether they are familiar with students’ psychology.

　　The reporter visited WeChat official account, a number of summer camps and research institutions, and found that only some institutions would take the initiative to explain the number of students participating in the camp and the teacher-student ratio on the page. Taking the summer sailing camp as an example, the reporter compared five institutions, such as a certain business school, a certain bear education and research, and a certain di, and found that only two of them indicated key information such as group capacity and teacher-student ratio.

　　An industry insider told reporters that summer camps and research activities are seasonal. Every summer, some institutions will temporarily increase and hire camp teachers. "There is no need for special qualifications and audits, and college students can also. It happens from time to time that a teacher takes more than 20 children. " She said that because many of them are products of cooperation between the organizers and foreign training institutions, the organizers are actually not very clear about the identity and source of camp teachers and research instructors.

　　"Overlord-style" signing rights protection is difficult to subcontract and leave hidden dangers.

　　The reporter visited and learned that the current summer camp mostly adopts the registration process of "paying first and then signing the contract", which also makes consumers have great opinions and brings many hidden dangers to the follow-up rights protection.

　　A parent in Tianjin told the reporter that this year is the first time for a child to participate in the camp. She deliberately chose an institution with long running time and high fees. The original duration of the activity was two weeks, mainly focusing on English training, but one or two days after the camp started, the children showed discomfort. "I can’t reach my English ability, and I don’t understand it in class." The parent said that due to an accident, and the contract stipulated that "the withdrawal of the camp due to personal reasons will not be refunded", which led to her later refund process being very tortuous.

　　The reporter consulted a number of summer camp organizers and found that the other party asked the parents to pay the full amount first, and then signed the agreement. Some organizations even refused to provide the model agreement before the parents paid the money. The staff of one of the most expensive summer camps said that the number of places in the camp is tight, and the children can be interviewed first after the parents pay the full amount, and they can only participate in the camp after the interview is passed, which is like the style of "supplier market".

　　Some parents also pointed out that online registration has become more and more common in recent years, and some institutions have no office space under the banner of organizing summer camps. In the event of a dispute, there is no organizer at all, let alone safeguarding rights.

　　In addition to the "overlord" signing, the reporter found that there are still layers of subcontracting in summer camp organizations, which brings hidden dangers to students’ safety and subsequent rights protection.

　　"Some places have no students, so they rely on subcontracting." An industry insider said frankly, "But what should I do if there is an accident in the subcontracting process? At present, no one can tell."

　　A parent in Taiyuan, Shanxi said that this year she signed up her children for a study tour in a famous Beijing school. I didn’t expect that the connection between the two places was "wrong". After the children arrived, no one picked up the station and no one arranged accommodation. They stayed in the unfamiliar city for more than 10 hours.

　　Strengthen industry supervision and establish a public platform

　　The reporter learned that the current summer camp, research and other activities still have vague supervision subjects and inadequate supervision responsibilities, and consumers are prone to face difficulties in safeguarding their rights. Once a child was scalded by boiling water during the summer camp, the organizer asked parents to go through the insurance claim procedure on the grounds that they had handled insurance, and did not bear other regulatory responsibilities. In recent years, similar cases of difficult rights protection have occurred frequently.

　　In the past few days, reporters have called seven provincial and municipal service hotlines and related personnel, including cultural tourism, market supervision and education departments, to ask where to complain about disputes in summer camps or study tours, but they have not got a clear answer.

　　According to industry insiders, the competent departments and supervisory responsibilities of related activities should be further clarified to ensure the safety of children and promote the sound development of the industry. "The competent and regulatory authorities should further clarify what safety protection can be achieved by the operators, and only after strict approval and filing can they be allowed to hold it." Zhang Jia, director of complaints department of Shanxi Consumers Association, said.

　　JASON ZHANG, director and associate researcher of the china tourism academy Research Travel Project, suggested that to standardize the market order of summer camps, we must first strengthen industry norms and supervision, especially to speed up the introduction of industry standards; Secondly, it is necessary to strengthen the qualification review of institutions to see whether the institutions are operating in compliance and whether there are false information; Finally, it is necessary to establish an industry public platform so that consumers can make public information inquiries.

　　"For parents, it is necessary to screen from the aspects of brand, price, word of mouth, product content and commitment. If unreasonable terms are found during the contract signing process, they should sign the contract cautiously." JASON ZHANG said.

　　Zhao Zhanling, a lawyer of Beijing Zhilin Law Firm, reminded that the contract is the most important thing. Parents should first read the contract carefully. If they find that there are unequal clauses, format clauses or clauses for the operator to evade responsibility, and there is no corresponding content to prevent problems before they happen, they should put forward additional clauses or indicate relevant clauses separately.

　　Recently, Taiyuan in Shanxi, Jingchuan in Gansu, Yizhang in Hunan, Siping in Jilin and other places have issued relevant regulations to standardize the diagnosis of contraindications to vaccination, including the establishment of an expert group for the diagnosis of contraindications to vaccination, the opening of a green channel for the elderly aged 60 and over, and the establishment of a ledger for the sales of contraindications.

　　Hunan Yizhang also requires that medical personnel who have issued certificates from relevant medical institutions should scientifically and accurately judge the contraindications and suspension of vaccination, and classify and evaluate the recipients who do have contraindications and basic diseases, and standardize the issuance of true and reliable vaccination contraindications or suspension of vaccination certificates, and must not shirk or refuse to issue certificates; The doctor who issued the certificate of contraindications should issue the certificate based on the real situation of the recipient’s illness, and must not resort to deceit. If there is any fraud, once it is verified, the responsibility of the doctor concerned will be investigated.

　　Expert groups for judging contraindications were established in many places, and the attending doctors issued relevant certificates.

　　The Paper noted that according to the news released by Jingchuan on August 27th, in order to strictly diagnose the contraindications of vaccination in Covid-19 and help the vaccination work in COVID-19, an expert group for the diagnosis of contraindications of vaccination in COVID-19 was established in Jingchuan County, Gansu Province.

　　The chief person in charge of the expert group is the vice president of the county people’s hospital and the chief physician of the Department of Cardiology. The members of the expert group come from the departments of respiratory medicine, cardiology, pediatrics, obstetrics and gynecology, radiology, laboratory, internal medicine, infection and so on of the county people’s hospital, and go to work normally on holidays.

　　According to the news, if it is confirmed by diagnosis that there are definite contraindications to vaccination in Covid-19, the attending physician will issue a diagnosis certificate of contraindications to vaccination in COVID-19, which will be signed by the leader of the expert group and stamped with the official seal of the hospital as the basis for contraindications to vaccination in Covid-19.

　　According to the report of Shanxi Evening News on August 26th, on the 26th, Taiyuan Epidemic Prevention and Control Office issued a notice, designated 14 medical institutions as designated hospitals to issue vaccination contraindications, and made clear the principles for judging vaccination contraindications and the issuance process.

　　According to the requirements, the medical institutions that issue vaccination contraindications must be public hospitals of Grade II and above. Taiyuan Epidemic Prevention and Control Office requires that all designated hospitals should set up an expert group to determine the contraindications of Covid-19 vaccination in the hospital, which is composed of professionals from neurology, cardiology, dermatology, respiratory department, pediatrics, intensive medicine, endocrinology, rheumatology and immunology, obstetrics and gynecology, and preventive medicine, and is responsible for judging, reviewing, training and guiding the contraindications of vaccination in Covid-19. It is necessary to designate special departments to undertake this work specifically and coordinate relevant departments to complete it together. Non-designated hospitals or personnel without professional training shall not issue taboo certificates.

　　In addition, after the evaluation doctor checked the relevant documents and medical information, combined with the comprehensive judgment of consultation and physical examination, if it is really a vaccination contraindication, he will issue a certificate of Covid-19 vaccination contraindication, the doctor will sign it, affix the official seal of the hospital, and record the information at the same time.

　　According to the news of WeChat WeChat official account, Propaganda Department of Anshan Municipal Committee of Liaoning Province on August 24th, Zhang Lu, Chief of Prevention, Control and Occupational Health Section of Municipal Health and Health Commission, said that the first batch of 13 designated medical institutions in the city issued contraindications for the people. Considering the principle of convenience for the people nearby, 13 medical institutions covered 7 counties and cities in the city. Each designated medical institution has set up an expert group for the certification of contraindications to vaccination in Covid-19, to give a scientific and professional evaluation on whether the diseases of patients are contraindications to vaccination in Covid-19, so as to ensure the vaccination safety of the people.

　　In some areas, it is required to classify and evaluate the recipients and establish a ledger.

　　Previously, Yizhang, Hunan, Siping, Jilin and other places also issued relevant regulations to standardize the diagnosis of contraindications to vaccination in COVID-19.

　　According to the news of WeChat WeChat official account, the Propaganda Department of Yizhang County Committee, on August 27th, six secondary hospitals, including Yizhang County People’s Hospital, were designated as the units that issued the vaccination contraindications and suspension certificates in Covid-19. Each unit clearly defined the departments (departments) that issued the vaccination contraindications and suspension certificates, and designated clinical medical personnel with intermediate or above titles to be responsible for issuing the vaccination contraindications and suspension certificates in Covid-19.

　　The news mentioned that medical personnel who have issued certificates from relevant medical institutions should scientifically and accurately judge the contraindications and suspension of vaccination, and classify and evaluate the recipients who do have contraindications and basic diseases, and standardize the issuance of true and reliable vaccination contraindications or suspension of vaccination certificates, and must not shirk or refuse to issue certificates; For the elderly aged 60 and above who apply for the Certificate of Vaccination Taboo and Suspension of Vaccination (attachment), it is necessary to open up a green channel and reduce the waiting time in line.

　　According to the aforementioned news, the doctors who issue certificates of contraindications should issue certificates based on the true condition of the recipients, and they should not resort to fraud. If there is any fraud, once it is verified, the responsibility of the doctors concerned will be investigated. If it is difficult to judge, it should be submitted to the county-level expert group for investigation and diagnosis of abnormal reaction to vaccination for discussion and decision.

　　According to the news of Siping Municipal People’s Government on August 23rd, the Municipal Health and Health Commission organized Covid-19 to train experts to judge the contraindications of vaccination and carry out supervision and inspection. The Municipal Health and Health Commission requires all supervision teams to immediately check the practices of all localities in implementing the judgment of contraindications, check the registration of contraindications at all vaccination sites, whether the relevant work requirements of the municipal party committee and municipal government are implemented, and whether the contraindications are established in all localities.

　　In addition, through training and supervision, we will further standardize the judgment and management of contraindications for vaccination in Covid-19, so as to avoid the situation that the judgment of contraindications is too large and the judgment is not strict, improve the vaccination ratio, realize that people without contraindications should be connected, and establish the city’s immune barrier as soon as possible.

Variety+feelings:

Stimulate "struggle empathy" and "emotional resonance"

"Hello, Saturday" adheres to the people-centered creative orientation. In conception, it reflects great feelings with the struggle of small people, shines into the great era with micro-perspective description, and stimulates the audience’s "struggle empathy" and "emotional resonance" through "memory killing".

In the third quarter of the program, a nostalgic classic space-time scene was opened from a brand-new perspective, and a dialogue was held with the past self, people, things or things, which led the audience to flash back instantly and had a strong emotional resonance.

"Big Head Sticker Shop", "Video Store", "Clothing Store" and "Snack House" … The opening of each program directly catches the audience’s eye with the nostalgic street view of Haoliu Street. The scenes of every shop on the street are truly restored, and the details are highly realistic. Through hard-core content elements such as past scenes, props, old videos, classic old songs, classic film clips, and things done in those years, the program allows the audience to complete an immersive journey through time and space.

In addition to creating a nostalgic atmosphere, content design also strengthens the emotional experience of the audience. For example, seniors and sisters gathered in "Haoliu Middle School" to recall the lush years with their classmates. By opening the "time capsule" to share the beautiful photos of each guest during their school days, they can talk to their own past in the story of recalling the past time and space, which will lead to more imagination and bring the audience’s thoughts back to the beautiful memories of middle schools and universities. Cyndi Wang and her fans for many years danced "Love You" in the same frame, which was full of emotion. The Haoliu Tea Party will create a special edition of the national style and tide in previous programs, leading the audience to enjoy the beauty of the national style. Especially when the familiar melody of the classic old songs sounded, the empathy ceremony of "one person sings for all people" was immediately formed.

This "retro card" played by "Hello, Saturday" set off a "memory killing" of the post-80 s and post-90 s on the whole network, directly hitting the hearts of the audience. From "collective memory" to "sentimental memory killing", nostalgia opens up the past space, making the narrative time and space of the program fluid, thus producing new stories. In the interweaving of the old and the new, it gives the old stories a new spirit of the times, which is an upgrade of the nostalgic theme in traditional programs and a breakthrough in the creative level of program content.

Variety+plot:

Various forms of creativity are presented, and traditional culture is full of new vitality.

It is a highlight of "Hello, Saturday" in the third quarter to connect the whole program with the plot. The main task plot of the single-phase program is running through, such as "the selection of the number one sweetheart", "Wangpu for rent", "the most tacit partner combination", "choosing the hero and heroine for the explosive TV series" Falling in love with you for the sixth time "and" the investigator of Haoliu Office gets the investigation fund ".The main task plot clue of the single-phase program integrates the original loose elements such as games, performances, interviews, etc., so that the program content and the main plot line have internal logical connections.

Chinese culture is extensive and profound, and the beauty of oriental classics contains rich cultural connotations. "Hello, Saturday" takes "the beauty of the East" as the theme, and takes you to appreciate the infinite charm of Chinese culture with traditional cultural styles such as satin dance and armor. In the program, Sun Yi appeared in a classical dance style and cooperated with Zhang Xiaolong to bring the stage of Xiao Meng. In the "beauty of collection" link, two precious manuscripts of the monthly card appeared, restoring the beauty of women’s manners in the 1970 s and 1980 s; Qin Xiaoxian and Dylan put on heavy armor to start the "catwalk" stage, reappearing the fearless spirit of heroes … The program allows the audience to immerse themselves in cultural charm and learn more about history.

Hunan Satellite TV has always adhered to the people’s position, adhered to the people-centered creative orientation, led the growth of young people through literary and artistic works loved by ordinary people, established cultural self-confidence, and defined their own trend culture of China youth. The program puts dance, music, conversation, performance, interaction, Live show, traditional culture and scenes in the play on the stage, and brings beautiful visual enjoyment to the audience with cross-border integrated arrangement and innovative artistic presentation, which fully reflects that the program group further improves its creative concept, embraces the life of the times, and truly takes going deep into life and taking root in the people as the first link of literary and artistic creation.

Variety+Hot Spots:

Practice dual-platform drive and deepen the strategy of integration and innovation

In the third quarter, "Hello, Saturday" brought into play the advantages of deep integration of Hunan Satellite TV and Mango TV in the creation and broadcasting, strengthened the content to create new, audio-visual highlights, and immersed the audience in the prosperity and development of TV art.

In the third quarter, we created constant surprises in the dance design and program scheduling, and the "blind box effect" brought by stage design was a highlight of this season. The long shots of many opening shows give a panoramic view of the street view of Haoliu Street, which fully reflects the consistently superb technical level and artistic expression of Hunan Satellite TV’s variety show creation.

"Hello, Saturday" closely follows hot topics, gives full play to its advantages of self-use and self-sufficiency, and interacts with hot film and television projects in real time, truly realizing the internal linkage between Hunan Satellite TV in cross-media and cross-category. The TV series "The Bottom Line" is a realistic TV series with the theme of rule of law, which is directed by the Supreme People’s Court, and shows the latest achievements of China’s judicial reform in a panoramic view. When the drama landed in the Golden Eagle solo theater of Hunan Satellite TV, actors and representatives also came to the program "Hello, Saturday" to explore the story behind "The Bottom Line" with the reasonable and unexpected variety scenes with the host team, forming a drama-integrated linkage mode. This kind of "drama-integrated marketing" closely following hot spots has changed the traditional thinking of "content flow" in the past, and realized the cross-screen "broken wall" and translation of attention. Digging deep into the content moat has become an effective way to amplify the mainstream voice.

In March this year, Hunan Satellite TV and Mango TV formally merged deeply and entered the era of 1+1 > 2. Hunan Radio and Television’s "two wings" and "two cores" realized the true "blood integration". From continuously producing high-quality film and television works and innovating media communication forms for many years, to strengthening the integration of technology and art, and the linkage of dual-platform creation and broadcasting, Hunan Radio and Television dual-platform has also continuously injected new kinetic energy into the development of China TV variety shows under the deep development of network integration. A practice of media integration with mainstream new media groups as the blueprint and dual-platform integration as the lever was creatively written on Malan Mountain.

Variety+Youth:

Show a true, three-dimensional and comprehensive look after 00.

Hello, Saturday is a gathering place for youth. The program focuses on more ordinary people. A group of students who were admitted to the ideal university in 2022 showed their college admission notices in the program and shared their love and yearning for the ideal university. Through a group of good young people of the new era who have ideals, dare to take responsibility, can bear hardships and are willing to struggle, the program talks with the young people of the times and leads the youth fashion.

Hello, Saturday is also an important carrier to lead the youth culture. Whether it is the interpretation of "long sleeves and big sleeves", or the "armored warrior", whether it is the melodious Miao songs or the passionate Mongolian dance, the program always remembers its mission and responsibility, strengthens its cultural self-confidence, leads young people to taste the beauty of national style, and conveys youth attitude, youth culture and youth aesthetics in its own unique way.

From the perspective of youth, "Hello, Saturday" highlights the values such as "human touch, companionship, youth, warmth", firmly occupying the hearts of young users and talking with young people. At the same time, based on the grasp of social emotions and hot spots of the times, the program broadens the boundaries of program content with strong innovation of mainstream content and innovative expression of mainstream values, guides the value pursuit of young people’s growth and development, opens collective youth memories every weekend night, realizes the same-frequency resonance of emotions inside and outside the screen, and completes the praise of youth and the expression of mainstream cultural values again and again.

From developing a new direction in content form to continuously upgrading its conception, "Hello Saturday" always adheres to positive value guidance, highlights Hunan Satellite TV’s firm mainstream media position, and endows innovative content with multiple forces on the basis of continuing its unique youthful temperament, which is another vivid practice to further upgrade and express the new ecology of "Youth China".

　　Last year, Beijing ushered in the closing year of the first phase of the national "Atmosphere Ten". What is the effect of five-year atmospheric control? Yesterday morning, the Municipal Environmental Protection Bureau held a press conference to take stock of the air quality improvement and air control measures in 2017 and the past five years.

　　(Reporter Wang Bin) The Beijing Youth Daily reporter learned from the press conference held by the Municipal Environmental Protection Bureau that the average annual concentration of PM2.5 in this city was 58 μ g/m3 last year, which was 20.5% lower than that of the previous year, and the national "Ten Atmospheric Articles" mission goal was achieved. Excellent days increased by 28 days compared with 2016, reaching 226 days; The number of heavy pollution days decreased by 16 days to 23 days. In addition, in the past five years, the average annual concentration of major pollutants in Beijing has dropped significantly, especially sulfur dioxide. In 2017, the average annual concentration of sulfur dioxide dropped to single digits for the first time, only 8 μ g/m3.

　　Last year, the heavy pollution day was only 23 days.

　　According to the relevant person in charge of the Municipal Environmental Protection Bureau, in 2017, the average concentration of PM2.5 in Beijing was 58 μ g/m3, down 20.5% from the previous year; It decreased by 35.6% compared with 2013. In addition, the average annual concentrations of sulfur dioxide, nitrogen dioxide and PM10 were 8 μ g/m3, 46 μ g/m3 and 84 μ g/m3, respectively, which were all improved year-on-year, and decreased by 20.0%, 4.2% and 8.7% respectively compared with 2016.

　　Among the above four main pollutants, the average annual concentration of sulfur dioxide has reached and is far superior to the national standard, but the average annual concentrations of nitrogen dioxide, PM10 and PM2.5 still exceed the national standard. Especially PM2.5, compared with the national standard of 35 μ g/m3, exceeded the standard by 66%. This shows that the improvement of air quality in Beijing will still be a long-term process.

　　In 2017, the number of days with excellent air quality in Beijing was 226, an increase of 28 days over 2016; The heavy pollution day was 23 days, 16 days less than that in 2016.

　　The number of days when air quality reaches the standard will increase by 50 days in five years.

　　Last year, it was the closing year of the first phase of the national "Atmosphere Ten". Compared with 2013, the average annual concentration of major pollutants in Beijing decreased significantly. Sulfur dioxide, the most obvious decline, dropped by 70.4%. Last year, the average annual concentration dropped to single digits for the first time, only 8 micrograms per cubic meter. Followed by PM2.5, with a decrease of 35.6%.

　　According to the relevant person in charge of the Municipal Environmental Protection Bureau, from 2013 to 2017, the number of days of air quality compliance in Beijing increased significantly, with 176 days in 2013 and 226 days in 2017, an increase of 50 days. Among them, the number of first-class excellent days increased from 41 days in 2013 to 66 days in 2017, an increase of 25 days.

　　From 2013 to 2017, the days of heavy air pollution in Beijing were 58, 47, 46, 39 and 23 days respectively, showing the characteristics of decreasing year by year; The number of days of heavy pollution decreased by 35 days in five years, and the incidence of heavy pollution decreased significantly.

　　In the past five years, the concentration of PM2.5 in various regions of Beijing has been decreasing year by year, and the decline is significant. In 2017, the concentration level in each region was significantly lower than that in 2013, and the overall spatial distribution was still characterized by high in the south and low in the north, but the concentration gap between the north and the south decreased.

　　In 2020, the average annual concentration of PM2.5 will drop to 56 micrograms.

　　What is the goal of improving air quality in Beijing in the future? Xiang Li, director of the Atmospheric Environment Management Office of the Municipal Environmental Protection Bureau, said that in the next stage, the Beijing Municipal Association will continue to improve air quality. The new Beijing Urban Master Plan clearly states that under normal meteorological conditions, the average annual concentration of PM2.5 in Beijing will drop to 56 μ g/m3 by 2020, and the atmospheric environmental quality will be fundamentally improved by 2035. "This has actually given a clear plan for the goal and roadmap of atmospheric prevention and control, and the next stage will strive to achieve this goal."

　　The overall improvement of the atmosphere is the result of "human efforts"

　　Controlling air pollution is the result of "people work hard and heaven helps". Liu Baoxian, deputy director of Beijing Environmental Monitoring Center, revealed yesterday that in 2017, the frequency of inversion was low, the air was dry and the frequency of north wind was high. In 2017, Beijing’s air quality improved significantly under the combined effect of continuous air pollution reduction and superimposed favorable atmospheric diffusion conditions.

　　So, how much power did "God help" contribute? Wang Shuxiao, a professor at Tsinghua University Institute of Environment, said that after preliminary assessment, the meteorological conditions have not changed much in the past five years. Take 2017 as an example. Last year, the meteorological conditions were more helpful in the fourth quarter. Cold air activities were frequent and the temperature was low. Four heavy air pollution processes occurred, resulting in five days of heavy pollution, which was significantly lower than the previous two years. However, the meteorological conditions in January and February 2017 were not conducive to the spread of pollution. "So overall, the meteorological conditions in each month of 2017 will be offset. In the case of slightly favorable meteorological conditions, the overall situation is ‘ People work hard ’ The result. However, the impact of meteorological conditions on air quality is complicated, and we are still continuing to evaluate it. " Wang Shuxiao said.

　　Yu Jianhua, chief engineer of Beijing Environmental Protection Bureau, said that the focus of "people’s efforts" is emission reduction, and the role of "God’s help" is diffusion. The intensity of "human efforts" can be quantified, but "God helps" can’t be planned. In any case, people will keep trying.

　　A new round of PM2.5 source analysis is underway.

　　In 2014, Beijing released the source analysis of atmospheric PM2.5 from 2012 to 2013. The main components of PM2.5 in the air are organic matter, nitrate, sulfate, crustal elements and ammonium salts, accounting for 26%, 17%, 16%, 12% and 11% of the mass concentration of PM2.5 respectively. Through model analysis, among the sources of PM2.5 in the whole year, the regional transmission contribution accounts for about 28% to 36%, and the local pollution emission contribution accounts for 64% to 72%. Among the local pollution contributions, motor vehicles, coal burning, industrial production and dust are the main sources.

　　In the past five years, based on this, the city has accurately controlled air pollution through emission reduction measures such as clean energy transformation of coal-fired boilers, loose coal treatment in rural areas, adjustment and withdrawal of enterprises that do not meet the functional orientation and pollution of the capital, and scrapping and transferring old motor vehicles. Practice has proved that the source analysis of PM2.5 is a powerful means to improve air quality.

　　In the past five years, the structure of atmospheric energy has been constantly changing, and pollutants have improved significantly. Correspondingly, the source of PM2.5 has also changed. In the future, will Beijing study and release a new source analysis of PM2.5? Liu Baoxian, deputy director of the Municipal Environmental Monitoring Center, said that a new round of source analysis is also in full swing, and relevant results will be released later.
