China News Service, February 25th, Liu Bingjiang, director of the Department of Atmospheric Environment of the Ministry of Ecology and Environment, pointed out on the 25th that it is necessary to scientifically formulate indicators for the decline of heavy pollution days in various regions during the "14th Five-Year Plan" period and strictly assess them.
According to the different causes of heavy pollution in various regions, different targets are assigned to reduce heavy pollution caused by human factors.

The Ministry of Ecology and Environment held a regular press conference on the 25th.
A reporter asked at the meeting that the "14th Five-Year Plan" suggested that heavy pollution should be basically eliminated. How will the Ministry of Ecology and Environment achieve this goal?
What are the major difficulties?
In this regard, Liu Bingjiang pointed out that the number of days of heavy pollution is one of the most concerned atmospheric issues of the people at present. “The CPC Central Committee’s Fourteenth Five-Year Plan for National Economic and Social Development approved by the Fifth Plenary Session of the 19th CPC Central Committee The "Proposals for the 2035 Long-term Goals" put forward the basic elimination of heavily polluted weather, which puts greater pressure on us. During the 13th Five-Year Plan period, we have achieved certain results. The proportion of days with severe pollution and above in the country has increased from 2.8% in 2015. It has dropped to 1.2% in 2020, and the improvement in key areas has been more obvious, from 5.0% to 1.9%. Beijing has dropped from 58 days in 2015 to only a few days a year. The results are quite obvious." And now it is severe. The characteristics of the polluted weather process have also changed significantly, the duration is relatively short, the concentration value is not like the original explosive meter, the peak value is greatly reduced, the range is relatively concentrated, and the severely polluted weather is basically eliminated.
"How to accomplish the arduous task of the '14th Five-Year Plan', we analyzed the composition of the number of heavily polluted days in the country. There are basically no severely polluted weather in the south of the Yangtze River. There are also a few cities between the Yellow River and the Yangtze River, which are mainly frequent. It is located in Beijing-Tianjin-Hebei, Fenwei, Northeast and Northwest, mainly in these four places, but also local. The causes of heavy pollution in different regions are not the same. The Beijing-Tianjin-Hebei and Fenwei plains are mainly coal-burning and industrial clusters. There are also many vehicles, and the three major structural problems are more prominent. The focus of Northeast China is to burn straw. Now in March, the season for burning straw is approaching. The amount of straw in Northeast China is relatively wide, and the window period for burning straw is short, which often overlaps with adverse weather conditions. It is prone to heavy pollution, and the people’s opinions are relatively large. We are working on this aspect. At the same time, the control of scattered coal in the Northeast is still on the way. The Northwest is the problem of the unreasonable industrial layout of some cities and the impact of sandstorms. ." Liu Bingjiang said.
Based on the above analysis, Liu Bingjiang said that there are three main areas of work.
The first is to scientifically formulate indicators for the decline of heavy pollution days in various regions during the 14th Five-Year Plan period and strictly assess them.
According to the different causes of heavy pollution in various regions, different targets are assigned to reduce heavy pollution caused by human factors.
"We will exclude factors such as sandstorms and forest fires."
Liu Bingjiang said that the second is to work part-time for specimens and strengthen the root cause measures.
The control of heavily polluted weather in the Beijing-Tianjin-Hebei region and the surrounding areas has been effective. You can see that many radical measures are indeed effective after the implementation, mainly the adjustment of industry, energy, and transportation structures.
The northeast region must increase the comprehensive utilization rate of straw, and the northwest region must strengthen the adjustment of the industrial layout. The difficulty lies in the Beijing-Tianjin-Hebei and Fenwei Plain. We will continue to arrange effective measures during the 13th Five-Year Plan.
The third is to scientifically carry out emergency response to severely polluted weather and actively treat symptoms.
The heavy pollution emergency has formed a set of fixed methods, which are more effective.
The 275,000 gas-related companies in key areas all adhere to industry performance grading and categorized policies. Each company has identified differentiated emergency emission reduction measures that need to be taken in a heavy pollution emergency.
After we predict that severely polluted weather will occur, the local government will issue an early warning to the society, and the emission reduction measures will be put in place. The duration of the pollution or the peak concentration will improve. To a certain extent, everyone will think that the pollution is not as serious as expected. In fact, It is an effective result of emergency emission reduction response.
Liu Bingjiang said that at the same time, during the 14th Five-Year Plan period, the Northeast, Northwest and other places will be guided to complete the list of emergency emission reductions for heavy pollution, including all gas-related enterprises, and focus on guiding local governments to deal with heavy pollution and also forecast The level of forecasting has improved, "Everyone should work together to eliminate the heavy pollution caused by man-made weather as much as possible."
