Study on Vegetation-cover Changes Based on NDVI Serial Images

Zhan Yu-lin DU Zi-tao

Abstract

The normalized difference vegetation index(NDVI) is one of key indicator of land vegetation cover feature.Taking the inversion NDVI serial images of MODIS data as an example,this paper analyzes the changes of vegetation growth trend and the change intensity of the NDVI from 2003 to 2006 in Shihezi municipality,Xinjiang province by the change vector analysis method.The distribution of vegetation cover changes intensity was obtained.The results show that there is no great change within past four years.
