Abstract

Vegetation cover not only takes as an import parameter for monitoring the vegetation situation of land surface , but also is an important indicator indicates the quality of the ecological environment and its changes. Therefore, in this paper , The Landsat TM images of 1989 and 2011 was used to extract the normalized difference vegetation index (NDVI) , then, the vegetation cover was obtained by NDVI using RS software ERDAS IMAGE 9.2, the results shown that : the increasing area of NDVI (0.2~0.3) was greatest, which was 141.41 km2, on the contrary, the reduced area of NDVI (0.4~0.5) was 340.29 km2, the lower vegetation coverage region covered the greatest increasing area, while the reduced area of higher vegetation coverage was maximum.
