Abstract

Making use of the MODIS vegetation index product provided by the Earth Observation System as the data resource and utilizing the close correction between the NDVI and the vegetation fraction, this paper has made a division of the desertification degree by means of NDVI and regards the division as the quantitative standard of desertification. The authors obtained the NDVI hierarchical distribution maps of 2000 and 2007 in Horqin sandy land and counted the corresponding percentages of the desertification of various degrees. At last, the paper comments on the desertification situation and dynamic change of the study area on the basis of the percentage of different-grade desertification land and the hierarchical distribution map offered by NDVI and the spatial distribution of desertification. The research results indicate that the desertification area had on the whole decreased from 2000 to 2007.
