Surface vegetation destruction

We all know that surface plants play an important role in water conservation and soil erosion prevention. Influenced by climate and human factors, the trend of desertification in China is obvious, and surface desertification leads to dust flying, which is also an important factor leading to smog.

Meteorological change

The main component of smog is aerosol, and the suspension of aerosol in the air is affected by meteorological conditions. For example, in places with a lot of rainfall in the south, precipitation has become less and less in recent years, and airborne dust has become more and more serious, thus aggravating smog; In recent years, the winter wind in North China is weak, and the smog can't be blown away.

In order to revitalize the declining economy, infrastructure construction is being carried out all over the country, especially the transformation of subways, railways and highways. Many cities present a scene of potholes, like a piece of city; Coupled with the real estate bubble, urban expansion, building dust has also become an important factor leading to serious smog.
