Landsat Thermal Mapper data were used to monitoring the vegetation cover change in east part of the Hunshandake sandy land. The NDVI in middle September are 0.47, 0.67, 0.65 and 0.33 in 1987, 1996, 1998 and 2001, respectively, which highly correlated with the rainfall of July and August. There are some regions showed vegetation degradation which could not recover in a short time, most of them located in poor vegetated areas. And the degraded area is increasing from 1996 (3.8%) and to 1998 (6.0%). The vegetation condition shows improvement in 2001, and this may associated with the effort made by Chinese government to improve the environment of Hunshandake sandy land.
