Why is the air quality in Chengdu so bad? Why?

Chengdu is located at the "bottom of the pot" in Sichuan Basin, and its air quality is below average in China. Because it is located in a basin, the weather has the greatest impact on Chengdu's atmospheric environment. On partly cloudy and continuous sunny days, a thermosphere is formed, and the suspended solids in the basin air are not easily blown away by the wind, and the air concentration increases. In addition, the air pollution index in Chengdu easily exceeds 100, and the air quality is naturally poor. If there are air pollutants that are not conducive to diffusion.

Moreover, there are many ethylene chemical plants and crude oil refineries in Chengdu, which are seriously polluted, and there are many chimneys around Chengdu. These are serious pollution sources, just go out and walk. The pollution of Chengdu's urban development blocks can't avoid automobile exhaust and urban expansion, and so on.

Urban development and environmental pollution are basically relative, and it is impossible for urban decision makers to stop developing for the sake of the environment. In recent years, environmental problems have received great attention without affecting the development of urban economy.
