Host Wang Hui, Lu Fengquan are slightly swollen: Good morning, friends! Today, I want to tell you about the changes in air quality in Beijing since July. From July 1 to 25, in 29, the city's air quality standards ranged from days to 22 days. This month's monitoring, two days exceeded the same period last year, accounting for 88%. At the same time, since the beginning of this year, the cumulative standard has reached several days to 145 days, accounting for 7% of the monitoring days, more than 15 days in the same period last year. The changes of atmospheric pollutant concentration of major pollutants, especially the concentrations of carbon monoxide, carbon dioxide and inhalable particulate matter emitted by traffic, decreased by 2% compared with the same period of last year. There is a special need to explain the air pollution index (API) in the past 2 days, which has dropped by an average of 2 percentage points compared with the same period of last year. Last year, these two standard days belonged to the same situation. Last year, the API index of the standard days was around 9 and 7. In layman's terms, the gold content of this year's target days has increased. In this case, the meteorological conditions under the corresponding weather conditions are conducive to the diffusion of pollutants. In the middle of the month, more cold air activities are frequent, high altitude and low temperature are conducive to the vertical diffusion of atmospheric pollutants, and repeated rainfall is conducive to the removal of pollutants in the air. Under hot and humid weather conditions, the air volume is very small. According to the monitoring, in many cases, it is less than about 1 meter or 1 meter in the wind, but it enters late, which is not conducive to the diffusion of pollutants. Under meteorological conditions, the accumulation rate of pollutants in the atmosphere slows down significantly. Our emission reduction measures have begun to show obvious effects.
Everyone talks about Zhang Yu. Why did she
reduce the concentration of air pollutants, and its accumulation rate slowed down? From July 1st, temporary motor vehicle restriction measures will be taken, and the emission standards taken on July 2th will continue to be reduced by 3%. On the basis of these measures and comprehensive control measures, enterprises with serious pollution will stop working, and in the process of heavy pollution construction, the comprehensive role taken before will be conducive to ensuring good air quality during the Olympic Games. I'm here to introduce the situation to you.
I'm glad to answer your question.
Moderator Hui Wang: Thank you, Duju Zhang. Mr. Du declared that Mr. Zhang Jianyu had anything to add. Zhang Jianyu:
Zhang Jianyu said, Zhang Yu
Thank you for the media. Good morning, everyone. My name is the American Environmental Protection Association, which is headquartered in new york and an American NGO. Upon receiving the invitation, the China Municipal Government has carried out a series of environmental protection work, policy research, pilot training, public awareness raising, education and participation activities in China since 1998. I am honored that in the 28 Olympic Games, Beijing ushered in such a once-in-a-lifetime opportunity. In such a great atmosphere, through our efforts, we made contributions to the Beijing Olympic Games and Beijing's environmental protection. Since 26, together with other non-governmental environmental protection organizations, media, social units, * * * have carried out a series of activities such as "car less than one day" and "green travel"? Move. We are glad to see that in the course of three years, we are getting closer and closer to the Olympic Games, and the enthusiasm of the broad masses of people for the Olympic Games is higher and higher, so as to make some real actions to promote the fuller blue sky in Beijing. The restrictive measures used are the new actions taken by the top 2 Beijing municipal government, and the restrictive measures taken by the government, with the support of Beijing Cheyouhui and other civil society organizations. On the other hand, I hope we can take the opportunity of odd-even behavior and change our way of traveling. This special online calculator can help you find out the starting point and starting point of this action if everyone participates, which can reduce the emission of pollutants and help you count the contribution made by Beijing. This action has been widely carried out, and people know the reaction. Now more and more people use online calculators. According to online statistics yesterday, there are about 5 million registered people who browse hundreds of thousands. I look forward to odd and even operations. From July 2th to September 2th, all the contributions of artificial green space eco-tourism can be recorded through online calculators, and finally become a personal Olympic tribute. The work introduced here welcomes all kinds of questions raised by the media and is willing to answer your questions.
Moderator Wang Hui: I took a reporter's question.
Wang Hui invited a reporter to ask her a question. Zhang Yu
Australian reporter: Yesterday, the evaluation index was 14. Please tell us where these evaluation figures got the second point. In Australia, athletes reflected some breathing problems. How to ensure the air quality during the Olympic Games?
The Australian reporter's question is Zhang Yu's

Arriving at a little middle school: I don't know what you mean by 14, but I can tell you that yesterday, the monitoring results of Beijing's air quality monitoring system showed that the air pollution index was 11. The second question, how to ensure good air quality during the Olympic Games, is very big, but you can make a brief introduction to our Olympic Commitment III, the first day of monitoring four major pollutants, sulfur dioxide, carbon monoxide, carbon dioxide and inhalable particulate matter, dedicated to improving air quality throughout the year and maintaining good air quality during the Olympic Games. The three commitments have been fully fulfilled. Beijing has established 27 automatic monitoring stations of a comprehensive air quality monitoring system, which are distributed in urban and rural areas all over the country. While monitoring the four pollutants every day and releasing them to the society, it should be said that there are excessive commitments. Second, committed to the improvement of air quality throughout the year, large-scale air pollution control in Beijing since 1998, the standard weather in 1998 was only 1 days, and the standard number of days in 27 was 246 days, accounting for 67.4%, an increase of 4 percentage points during the nine-year period. Dirty? The pollutants, in the order mentioned above, decreased by 6.8%, 39.4%, 1.8% and 17.8%. After the successful Olympic bid, the four pollutants decreased by 34%, 26%, 7% and 9%. At the same time, I can clearly tell you that the three top four pollutants have remained stable throughout the year and reached the national standards. Although the particulate matter did not meet the standards, it also declined to some extent. Two promises should be respected.
The third commitment is to ensure good air quality during the Olympic Games. It is clear that the answer to this question is that we can make it after the Olympic Games. However, according to the achievements we have made, the measures we have taken and the measures we are taking, the air quality during the Olympic Games makes a scientific and logical reasoning, which only introduces the progress we have made and the introduction of air quality improvement this year. As we all know, the main problem of particulate matter every year, as mentioned above, is whether it is complied with. It is a basic contradiction that 7% of the air quality standards and 3% of the air quality during the year. It took us two years to participate in the organization of investigation and feasibility study, and the participation of research institutions, universities and experts from many disciplines in six provinces around Beijing, which led to the adoption of the environmental protection plan of the Ministry of Education and the development of the Olympic Games safety plan for air quality in the people's government of Beijing. This plan was approved by the State Council last October, and the main contents included a temporary reduction measure for comprehensive control measures before and during the Olympic Games. The comprehensive control measures of centralized reflection, the 14th stage air pollution control measures notified in advance of the Olympic Games, were released by the Beijing Municipal People's Government earlier this year, including the national standards for motor vehicle pollution control, coal pollution control, dust pollution control and industrial pollution control, and 21 measures for automobiles, while the China IV fuel standard was implemented. Newly renovated coal-fired facilities all implement the same emission standards and gas facilities. The emission standards of closed coal-fired facilities are the most stringent standards in the world and have played a very important role. Therefore, in the first half of this year, the main pollutants were all lower than about 2% of the same period last year (excluding inhalable particulate matter, down 7%), and the air quality was further improved significantly compared with the same period last year.
/> The third part is the temporary emission reduction measures. During the Olympic Games, Beijing's air quality has improved, and the air quality during the Olympic Games can be guaranteed to be figuratively compared to a triple jump. The first stage is to improve air quality (whichever is earlier). 9. Air pollutants are reduced. The second stage is a comprehensive management measure to achieve the goal of improving air quality. In the third stage in July this year, temporary measures are taken to reduce greenhouse gas emissions. The initial results of this temporary emission reduction measure to improve air quality. The analysis can confidently tell you that we will ensure good air quality during the Olympic Games. Thank you for further improving the air quality in Beijing!
CBS reporter: Can I put your answer as a refined one? There are a lot of motor vehicles, and every city with a large population, Athens and Los Angeles, has this problem. Every city wants their achievements in air quality control to be the best. I also congratulate you on your achievements and reduce the pollution level, but no matter what they have done in the past few months, this can't guarantee the athletes' air ability to meet the needs of the competition.
CBS reporter's question Zhang Yu she

Du Xiaoqi: This question has always been a clear answer. I have just introduced it, and the conclusion can ensure good air quality during the Olympic Games and provide a good atmosphere for athletes. The authoritative IOC Medical Committee has made a conclusion, which can be guaranteed completely. thank you
reporter from los Angeles times: yesterday, the air was gray. how to explain it? For a few minutes, my lungs walked uncomfortably on the street.
Zhang Yu, a reporter from the Los Angeles Times, asked her a little
: I didn't know that the BBC was not coming today. I originally wanted to explore two common-sense questions with him here. I don't know if you noticed that on July 8 this year, the BBC sent two photos to related websites in the same building. One photo was translucent, and the gray color indicated that the air quality in Beijing was still problematic. Our attitude is very clear, and there is indeed a need to further improve the air quality in Beijing, because in 28, 7% of the air quality standards and 3% of the air quality standards, which is a very realistic problem. It is unscientific to evaluate air quality by photos, because photos, as visual products of works, can't reflect the essential characteristics of air quality monitoring data display, instead of using naked eyes to feel.
In 28, the air quality standard was 7% and the air quality standard was 3%. How to ensure the air quality standard during the Olympic Games is a very simple problem. Professional or textual research is difficult to answer the air quality in Beijing. For the whole year, 3% of the air quality standards, particulate matter pollutants. At the same time, it also tells us that this distribution of 3% this year is uneven, which means that in this season, excessive inhalation of particulate matter may occur, which is not conducive to the spread of pollutants. For example, in spring, dust is easy to produce, but the days when pollutants cannot be reached often spread, which is conducive to diffusion and removal. The air quality is better, and the difficulty of ensuring air quality is relatively small. In this case, the annual particulate matter is lower than the standard, and the role of safety procedures in formulating the Olympic air quality assurance plan is to reduce the overall pollution level of urban pollutants. The standard weather in July this year is only one couple days compared with the same period last year, but it is 2 percentage points lower than the average compliance data in the same period last year. Dirty? With the decrease of the overall level of pollutant emission, we can ensure that unqualified days or less will not appear in this period, which is why it is very important to provide good air quality for the Olympic Games, so as to ensure that on the basis of this, we should pay attention to studying this fact. Thank you!
Beijing Youth Daily reporter: I want to mention Mr. Zhan, Beijing Meteorological Bureau. I don't know, what was the verdict of the Meteorological Bureau and the opening ceremony of the Olympic Games that day? As for whether you know any specific measures, if it is more likely to rain, what measures will be taken to reduce the rain? thank you

A question from a reporter from Beijing Youth Daily, Zhang Yu.
Guo Hu: This question is about the relationship between meteorology and the environment. Journalists and friends are very concerned about the weather at the opening ceremony, the weather recently arranged by the press release center and the meeting of the Olympic Games at the opening ceremony under the weather conditions (from August 8 to August 24). Tell the reporter at that meeting and make an introduction to some friends.
Guo Hu, answering a reporter's question, Zhang Yu told her
nine channels in Australia: venues tens of meters away from sight, gyms except athletes, and clear air. How far is it for us to see beautiful venues?
Australian Channel 9 TV reporter asked Zhang Yuta
Du Shao: Actually, this question should be a common answer of Director Guo Hu. Many of us have spent a lot of time to see the Bird's Nest clearly this year and take beautiful photos to make it pleasing to the eye. But to be honest, in some cases, it is not clear to see, for example, fog, rain, watching the bird's nest in the dark, which is a natural phenomenon. Just like the bathroom where you take a bath, you may not be able to see the opposite side, but there is no pollution. Of course, it doesn't mean that there is nothing wrong with our air quality and it really needs to be further improved, so I want to say a common-sense question. People often ask me how to judge the blue sky. The answer is simple, a popular saying, blue sky and air quality, but it can't be completely equivalent to a standard blue sky, or to determine the environmental significance is to look at the air quality monitoring index, and speak with scientific data. thank you
Guo Hu: There have been many days of precipitation in Beijing since the beginning of this year. In June this year, the precipitation days in Beijing were 14 days and 4 days, which was ten days in a row compared with the normal precipitation from late June to July 1. Thundershowers were conducive to the spread of air pollutants, so by the end of June, Beijing was basically better than two fine days. This time, the blue sky and people may feel different. It is still a conceptual problem to consider how to be cloudy or standard, standard day and blue sky. In addition, due to the number of days of precipitation, the precipitation in Beijing this year will avoid a very low level of humidity than normal. At this time, the relative humidity in cities will reach 7% to 8%. Evening arrival
