我国沙尘暴天气成因的分析与研究

Analysis and research on the causes of sandstorm in China

沙尘暴是内陆干旱和半干旱地区较为常见的一种灾害性天气现象,主要原因在于冬春季节降雨量较少,植被覆盖率较少,地表过于干燥,地面抗风蚀能力不断下降,一旦大风刮过,会卷起地表大量地表沙尘物质,从而形成沙尘暴天气。本文对沙尘暴天气的形成过程及成因机制进行了分析,希望能够为沙尘暴的预防治理提供参考借鉴。

Dust storms are a common disastrous weather phenomenon in inland arid and semi-arid areas.The main reason is that there is less rainfall in winter and spring,less vegetation coverage,too dry ground,and continuous decline in ground resistance to wind erosion.A strong wind blows up a large amount of surface sand and dust on the surface,resulting in a sandstorm.This paper analyzes the formation process and cause mechanism of sandstorms and sandstorms,hoping to provide reference for the prevention and management of sandstorms.
