Abstract

Desertification has a close relationship with the sand vegetation cover in Ordos region. The dynamic monitoring to the sand vegetation cover using satellite data can provide useful information to understand the desertification in Ordos region. In this paper, we built the correlative model between the sand vegetation cover and the modified soil adjusted vegetation index (MSAVI) in Ordos region. Satellite data must be processed before these data are used in the correlative model. First, the atmospheric effects were corrected using the method of bare sand soil line. Then, the soil background effects were reduced using the MSAVI. The results of this study indicated that the maximum cover of the sand vegetation in Ordos region was 60%.
