The result shows that desertification is serious in the study area. Various types of desertification land add up to 370000hm~2, accounting for 39% of the total land. From l995 to 2000,the serious desertification land, where vegetation cover is below 30%, extends with the speed of 61hm~2 per year.

主要进行了：①农、牧业变化的历史轨迹与生态环境演变的实证研究，从大的历史尺度寻求农、牧业变化与沙漠化之间的互动关系；②农、牧业选择变化的驱动过程研究，从较短的时间尺度进行高分辨率的过程跟踪与解析，重点分析农牧民的行为机制；③农、牧业选择变化对沙漠化过程的动因解析研究，重点解析&滥垦、滥牧、滥樵&产生的深层次根源，为沙漠化防治战略的制定提供理论依据；④生态建设策略的比较与转型方向的研究。

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.
