Brought forward and reasoned the forming mechanism of Maowusu sandy land. Based on the analysis of the development of Holocene rivers and related loess and windsandy geomorphology, the paper put forward the forming mechanism of Maowusu sandy land as follows: while the climate became dry, the exterior channels extended backwardly and cut through the remained lake system of ancient Hetao lake. This resulted in the rapid discharge of underground water. The vegetation living on this water resource was destroyed completely. Then the sand began to form.

对毛乌素沙地的形成机制进行了新的探索基于对过渡地带全新世河流及其相关的黄土和风沙地貌发育、土地利用变化等分析，提出毛乌素沙地的形成机制：在气候变干的同时，外流河谷溯源延伸，切穿了长城以北河套古湖残遗湖系，使地表地下水迅速外泄，原靠湖系水资源维系的生长在河套古湖湖滨沙堤形成的沙地上的非地带植被的生存条件被彻底摧毁，而起沙。

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。

It can provide some theoretic gist for resource value of water and soil in sandy land to indicate the change and law of soil moisture character, as well as the water circulation and balance mechanism in sandy land, at the same time, it have important practical significance to protect limited water resource, improve using efficiency of water resource,control desertification, choose and educate sand binding plant, renew and restore degraded ecosystem, as well as the economy benefit of irrigative agriculture and intending trend of development.

揭示沙地土壤水分特征的变化规律以及沙地水循环和平衡机理，可以为沙地水土资源评价提供一定的理论依据，同时对于保护当地有限的水资源和提高水资源的利用效率，以及沙漠化防治，固沙植物的选育，退化生态系统的恢复与重建，灌溉农业的经济效益和未来的发展趋势都具有重要的实践意义。
