In order to explore the grain-size distribution characteristics and geo-genetic types of land desertification in Mo Us desert, the research on the grain-size characteristics of sediments since late Pleistocene has been carried out in the desert area and neighboring area such as inside desert, sand covered loess plateau, loess plateau and river valley. The research result shows that sediments of different geologic genetic types are the fundamental material source of sandy desertification in these areas and the distinguishing of different types of the sediments is the theoretical basis of classification of different geogenetic type of sandy desertification. The contribution of different geological roles on the land desertification and its significance to prevent and deal with the land desertification have also discussed.

为了研究毛乌素沙地沉积物的粒度特征与土地沙漠化的地质成因类型，通过系统研究沙地及相邻地区晚更新世以来在沙地内部、覆沙黄土区、黄土高原和河流谷地与湖泊等不同地质构造地貌条件下所形成的沉积物粒度特征，指出不同地质成因类型的沉积物是这些地区土地沙漠化的物质基础，区分不同类型的沉积物也是构成不同地质成因类型土地沙漠化分类的理论基础，探讨了不同地质作用对土地沙漠化的贡献及其对土地沙漠化防治方面的意义。
