In order to examine to what extent the oases surrounding the Taklimakan Desert have been converted into a desert, study was made by comparing the satellite images in the early period of 1960 with those of the satellite in the same district in recent years. As a result, the following have been explained. In the district surrounding the Aksu oasis, the oasis in the edge of the Taklimakan Desert, farmers in the coastal district of China are forced to move to the region as a policy of the Chinese Government, staring from around 1950. The farmers are asked to be engaged in converting the desert into a large-scale cultivating land of cotton as economic products, making use of a voluminous amount of the water flowing from the Tienshan Mountains. The area of the land that was changed from a bare land into a cotton cultivating land for the period of 40 years ranging from 1960 to 2000 is 2160 square kilometers. As a result of such conversion, the area of the farming land was multiplied and conve … More rsion of the oases into a desert apparently followed a path of regression. However as a backlash of inadequate irrigation, the level of underground water was heightened. Thus salts are liable to cover a large number of farming lands, and the lands had to be deserted. This resulted in degradation of many of the lands. Also such a type of the land has become causes of generation of dust storms. Meanwhile in the southern edge of Taklimakan Desert, water resources from the Qunlun Mountains are not abundant enough to be utilized in comparison with those resources in the southern edge, and slight expansion of the farming land was noticed upstream in the oasis. However scanty water resources were consumed downstream, which has invited regression of farming land contrarily to the above because scarce water resources were consumed upstream. Fewer water resources are available in the south than in the northern edge, which prevents the level of underground water from being heightened. Thus it is contrarily explained that just a few amount of salts of farming land is in existence. As seen above, it can be pointed out as a problem of the whole of Xinjiang Uyghur that the social backgroud such as a water resource controlling policy of the autonomous government of the Xinjiang, Uyghur, as seen, for example, in inadequate water distribution to farmers expedites destruction of the land. In the northern edge of Taklimakan Desert, as a backlash of inadequate irrigation, the level of underground water was hightened. Thus salines are liable to cover a large number of farming lands, and the lands had to be land degradation. This resulted in degradation of many of the lands. In the southern edge, water resources from the Qunlun Mountains are not abundant enough to be utilized in comparison with those resources in the southern edge, and slight expansion of the farming land was noticed upstream in the oasis. However scanty water resources were consumed down stream, which has invited regression of farming land contrarily to the above because scarce water resources were consumed upstream. Fewer water resources are available in the south than in the northern edge, which prevents the level of underground water from being hightened. Thus it is contrarily explained that just a few amount of salines of farming land is in existence. Less

为了考察塔克拉玛干沙漠周边绿洲转化为沙漠的程度，将1960年早期的卫星图像与近年来该地区的卫星图像进行了对比研究。因此，已解释了以下内容。在塔克拉玛干沙漠边缘的阿克苏绿洲周边地区，中国沿海地区的农民被迫迁往该地区，这是中国政府从1950年左右开始的一项政策。农民们被要求利用天山的大量水流，把沙漠变成大规模种植棉花的经济产品的土地。从1960年到2000年的40年间，从裸地变成棉花种植地的土地面积为2160平方公里。由于这种转换，耕地面积成倍增加， ...更多信息 从绿洲到沙漠的演变显然是沿着一条退化的道路进行的。然而，由于灌溉不足，地下水位升高。因此，盐很容易覆盖大量的农田，这些土地不得不被遗弃。这导致许多土地退化。这种类型的土地也成为沙尘暴产生的原因。在塔克拉玛干沙漠南缘，昆仑山的水资源相对于南缘而言，不足以充分利用，绿洲上游的耕地面积略有扩大。然而，下游却消耗了稀缺的水资源，上游消耗了稀缺的水资源，导致了与上游相反的耕地退化。南部可用的水资源比北方边缘少，这使地下水位无法提高。从而反证了耕地盐分含量少的事实。如上所述，可以指出，作为整个新疆维吾尔族的一个问题，社会背景，如新疆维吾尔自治政府的水资源控制政策，例如，农民的水分配不足加速了土地的破坏。在塔克拉玛干沙漠北方边缘，由于灌溉不足，地下水位升高。因此，盐碱地很容易覆盖大量的耕地，这些土地必须是土地退化。这导致许多土地退化。在南缘，来自昆仑山的水资源与南缘的水资源相比不足以被利用，并且在绿洲的上游注意到农业用地的轻微扩展。然而，下游却消耗了稀缺的水资源，上游消耗了稀缺的水资源，导致了与上游相反的耕地退化。南部可用的水资源比北方边缘少，这妨碍了地下水位的升高。从而反证了耕地盐碱化程度低的事实。少
