Debris flow caused by heavy rain in Aba, Sichuan Province has caused casualties. Can mudslides appeal to us to treat nature rationally?

Yes, because we treat disasters from nature correctly, we can unite and actively prevent them.

Different landforms have different effects on the formation of rainstorm disasters. Because of their blocking effect, the plateau and mountain often form bypass flow and sulfur climbing, which leads to heavy rain. Under the action of heavy rain, the plateau and mountainous areas are most likely to induce secondary disasters such as landslides and mudslides. Generally speaking, basins and mountain plains are steep, mostly terraces, with good drainage conditions and small areas affected by floods, which will not cause serious disasters.

However, when encountering high-intensity and large-scale rainstorms, such as continuous rainstorms, it is easy to cause serious disasters surrounded by floods, and the relatively developed industries in the basins and Pingchuan areas at the tip of the mountain increase the vulnerability of rainstorms in these areas. In the plain area, because of the flat terrain and vast area, there are few mountain disasters dominated by shocks, and most of them are floods.

Rainstorm is a disastrous weather, often accompanied by serious soil erosion, a large number of crops flooded and other major economic losses. The main harm is waterlogging caused by poor drainage, and the soil pores are full of water, which leads to the lack of oxygen in the roots of land plants and inhibits physiological activities. The flood caused by heavy rain flooded crops, making it difficult for crops to metabolize normally. Flash floods and river floods caused by heavy rains not only endanger crops, fruit trees, forestry and fisheries, but also destroy agricultural cooperatives.

Heavy rain will cause flash floods, rivers overflow and dams burst, causing huge economic losses to the people and the country. The main causes of heavy rain are weather and climate. After the rainstorm, the geographical environment has become an important factor affecting the occurrence of disasters. Geographical environment includes topography, geographical location and river distribution. China has a vast territory and very complicated terrain. Is there a geographical environment such as mountains, plains, basins and hills?
