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。

But at the same time,itexisted in the fact that the water environment was amended,showingthat many lakes and ponds such as Hong Jiannuo Lake appearing andexpanding in the end of Qing dynasty.4.The vegetation in Mu Su Desert passed through several phases inhistorical times,the main phases are:the species composition ofvegetation community was gradually simplified;xeromorphous and sandyplant increased;the status of desert vegetation rose evidently.However,the change of vegetation zonation means that forest plainchanged into drought plain did not occur.5.The main modality of Mu Su Desert land degenerating has beendesertification,it had occurred before human activities intervenedintensively.Two-thirds of land has been desertification at variousdegrees.

但与此同时，也存在着局部的水环境改善，突出表现为红碱淖等湖沼在清末民初的出现和扩大。4、毛乌素沙地的植被在历史时期经历了群落种类组成渐趋简单、旱生沙生资源植物增加、荒漠植被地位明显上升等变化，但是并不存在由森林草原到干草原的地带性植被变化。5、沙漠化是毛乌素沙地土地退化的主要表现形式，在人类活动强烈干预以前就存在着，秦汉以来，有大约2／3的土地发生了程度不同的沙漠化。

Needle-shaped clumps camel grass self-serving, a growth of the Susu, they one by one toward the wind direction, the body was tilted like difficult and stubborn stand upright in the Great wall of desert, which are especially small ones like wire-line the same root, the stone with deeply plunging to a desert, desperate to learn the distant snow-capped mountains over the bottom of infiltration of water vapor and stubbornness, for the desert, the Gobi, in order to win a trace of green earth.

针叶状的骆驼草自顾自的一丛丛、一簌簌的生长着，它们一个个迎着风的方向，身体呈倾斜状艰难而又顽强地挺立在大壁荒漠，它们把细的像钢丝线一样的根，深深地扎进戈壁的石缝，拼命汲取着遥远雪山底层浸渗过来的水气，固执地为荒漠、为戈壁、为大地争得一丝绿色。

The SO2-4 and Ca2+, particularly SO2-4, are major ions in snow and ice of snow pits on Haxilegen Glacier No.51 of Kuitun river, where its ion chemistry in snow pits is different from that on Hami Miaoergou FlatTopped Glacier, which is most likely related to the geographical location of Hami Miaoergou FlatTopped Glacier that is located in the leeward site of the Taklimakan desert, Shanshan desert and Gurbantunggut desert, and also probably associated with the elution process in snow pits and altitude effect of deposition flux.

SO42-和Ca2+是奎屯河哈希勒根51号冰川雪坑中的主要离子（尤其是SO42-），其雪坑离子化学特征与哈密庙尔沟平顶冰川差别较大，可能与哈密庙尔沟平顶冰川处于塔克拉玛干沙漠、古尔班通古特沙漠和鄯善沙漠的下风向相关，还可能与雪层内淋融作用的强弱和沉积通量的高程效应有关。

Analysis of sedimentary facies and the multiple proxy indexes indicate that climate have many times dry-cold and warm-wet changes in the desert-loess transition belt since the last interglacial, and environment undergone alternations from warm semi-humid forest steppe, temperate-humid shrub steppe, semi-arid steppe and dry-cold steppe, desert steppe to desert.
