Abstract The remote sensing images in 1980s, 1990s and 2000s were interpreted to disclose the desertification process of Mu Us Sandland, and to discuss its driving mechanism. The degree of desertification in Mu Us Sandland decreased in the past 20 years, and the cover of vegetation increased correspondingly. Meteorology factor and anthropogenic factor account for these change in Mu Us Sandland. Increased temperature is the key factor in the increase of vegetation cover, and the effect of anthropogenic factor is manifested by the great increase of farmland and woodland.
