are clear sky and white clouds. In the past summer, beautiful pictures of blue sky and white clouds always gather in the circle of friends of Sichuan people. So, what is the quality of Sichuan’s atmospheric environment this year? The reporter learned from the Provincial Department of ecological environment yesterday that the air quality report of the province from January to August this year was released recently. The excellent days rate of the whole province in the first eight months was 89.7%, up 2.2% year on year, and the air quality continued to improve.
reports show that from January to August this year, the rate of excellent days in the three major air quality key areas of our province has increased steadily. Among them, Chengdu Plain increased by 0.9%, southern Sichuan increased by 3.6%, and Northeast Sichuan increased by 3.7%. In terms of
, the average concentration of PM10 decreased significantly. From January to August this year, the average concentration of PM10 in the whole province was 47.2 μ g / m3, down 10.6% year on year. Among them, Chengdu Plain decreased by 8.0%, southern Sichuan by 10.5% and Northeast Sichuan by 14.0%. At the same time of
, the effect of PM2.5 remediation is obvious. From January to August this year, the average concentration of PM2.5 in substandard cities was 33.6 μ g / m3, down 13.0% year-on-year. Among them, Chengdu Plain decreased by 11.3%, southern Sichuan by 12.7%, and Northeast Sichuan by 14.7%.
“although the air quality continues to improve, the prevention and control progress of motor vehicle pollution in our province is slow.” The person in charge of the Provincial Department of ecological environment said that so far, 32000 diesel trucks have been sampled and tested in the province, only 55% of the target task has been completed.
in addition, at present, there are 62 sets of remote sensing equipment (including black smoke capture equipment) for vehicle exhaust monitoring in 16 cities (prefectures) of our province, and the remote sensing monitoring of vehicle exhaust gas is 4.75 million vehicles. Some cities have not installed remote sensing monitoring equipment, or the transmission rate of vehicle emission inspection data platform does not meet the requirements of 95%.
straw incineration has been a long-standing and difficult problem affecting air quality. The person in charge said that after entering autumn and winter, we have also entered the sensitive period of straw burning in our province. It is suggested that all localities should strictly implement the four level responsibilities of “city, county, township and village”, strengthen the comprehensive utilization and prohibition of straw burning, and prevent straw burning pollution in the open air. At the same time, we should actively optimize the emergency plan and emergency management and control list for heavy pollution weather, and make preparations for air pollution prevention and control in autumn and winter in advance, so as to ensure the continuous stable and good air quality.
