The average annual precipitation in China is increasing. What impact will this have on China's natural environment?

What impact will the increase in precipitation have on China's natural environment?

Continuous heavy precipitation is likely to lead to secondary disasters, such as flash floods, mudslides, landslides, waterlogging and crop disasters.

First, the flood disaster. If there is heavy rain this year, it will first cause serious waterlogging in the area and serious collapse of the drainage system, leading to flooding in the whole area. Once people travel in this disaster, they will be strictly restricted and vehicles and other things will be washed away by these floods. Almost all the floods in the history of our country were caused by rainstorm, such as July flood in the Yangtze River basin 1954, August flood in Hebei province 1963, September flood in Henan province 1975, and catastrophic flood in the whole basin of our country 1998. 2. Landslides. Landslides will occur in mountainous areas. If there is a lot of soil on the mountain, it is easy to landslide. The soil on the mountain will fall down the slope with the rain, and the washed objects will flood people's houses.

3. Debris flow: Debris flow will occur in some places with more mountains. Debris flow is accompanied by the rolling of stones, all of which roll down from the heights on the mountain. If there are people down there, it will cause casualties. ?

The crops are seriously damaged, mainly because there are large areas of food crops in rural areas. Once there is a rainstorm, farmers' crops will be submerged by rain, and crops will be soaked in water for a long time. This lack of sunshine has a serious impact on the development of crops. More seriously, crops can be washed away together. Too much rain can also cause pests and crops will rot. Generally speaking, precipitation, especially large-scale persistent rainstorm and concentrated rainstorm, not only affects industrial and agricultural production, but also may endanger people's lives and cause serious economic losses.
