Abstract:: In this paper, we took Zhengxiangbaiqi region in the classical sand land Hunshandake as the study area, and used the spatial analysis function of CIS to analyze the change characteristics of desertification. The results are as followings: the area of desertification in Zhengxiangbaiqi region has the relationship with the elevation, the area of desertification decreased and with the increase of elevation; in the grades of one, three and four, the area of desertification changes a lot, while in the grade of two, five and six, the area of desertification changes little. When taking measures to protect, we should pay more attention to the grades of one, three and four, and change the higher degree into a lower degree to alleviated the desertification; in the year of 1989, 2000 and 2007, the desertification of the classical sand land of Hunshandake in the Zhengxiangbaiqi region is spreading, and the desertification of different degree changes in different elevations. The others all deteriorated greatly except certain extent alleviation in the grade two.
