摘　　要：文中以吉林省西部地区为研究对象,采用粒度分析和相关分析的方法,从下垫面提供粉尘能力和人类活动两个侧面来探讨该区沙尘暴的形成.总结出吉林西部地区很强的地表供沙能力是沙尘暴形成的物质基础;人类不合理的土地利用方式对沙尘暴的发生也起到了推动作用.In this paper, we take the west of Jilin province as the research object, discuss the factors of the formation of sandstorm through two different aspects, namely, the ability of offering dust by underlying surface and human activity. The author, using the particle size analysis and the correlation analysis, draw the conclusion that the strong ability of offering sand is the material base of the formation of sandstorm, and unreasonable land use is： the west of Jilin province ; sandstorm ; promotes the formation of sandstorm. underlying surface
