Air quality in Wenjiang, Chengdu
Wenjiang, Chengdu will be cloudy tomorrow, with the highest temperature of 14℃ during the day and the lowest temperature of 5℃ at night, and the south wind. Wenjiang District is located in the hinterland of Chengdu Plain, with flat terrain, low wind speed, high static wind frequency, frequent inversion temperature, low boundary layer height and poor atmospheric diffusion conditions. The overall emission of the whole region is relatively small, but due to the relatively small area of Wenjiang District and relatively large emission intensity per unit area, it is easy to quickly accumulate major air pollutants due to transmission in surrounding areas.
In 2020, the construction area of housing construction in our district is second only to Shuangliu District among surrounding districts (cities) and counties, and the development of unit area is obviously higher than that of surrounding districts (cities) and counties. Due to unfavorable factors such as high emission intensity of primary particulate matter at the construction site and adverse meteorological conditions, pollutants are easy to accumulate rapidly.
How can we have good air quality?
Reduce pollutant emissions. Traffic emissions, factory waste gas, coal burning, etc. Is the main cause of air pollution. Therefore, we should choose public transportation, cycling or walking as much as possible to reduce the use of private cars; At the same time, support and promote clean energy, reduce coal use, and reduce pollutant emissions from the source.
Second, plant trees. Plants can absorb carbon dioxide in the air and release oxygen, which plays an important role in improving air quality. Therefore, we should actively participate in afforestation activities, improve the green coverage rate and promote the improvement of air quality.
Third, raise awareness of environmental protection. Protecting the environment and improving air quality require the participation of the whole society. We should start from ourselves, improve environmental awareness, do not litter, do not set off fireworks and firecrackers, do not cut down trees at will, and achieve civilized travel and civilized life.
