Abstract:: Using space analysis technologies RS and GIS, and taking the remote sensing image as the major source of information, an analysis is performed on the dynamic variations of desertificated land of the study area, with the data acquired by virtue of visual interpretation as well as the field survey data. The results show that the desertificated land of the study area is generally in an improved situation, among which the most obvious improvement is the area diminution of the shifting sandy lands, which mainly converse into fixed and semi-fixed sandy lands. It is thought by analysis that the laws and regulations implemented by the central and local governments on sand prevention and control provide policy guarantee for the improvement of desertificated land. The realization of various ecological projects and the enhanced public awareness of protection of ecological environment play a promoting role in it, and the sustained and steady development of regional economy provides strong financial support for the same.
