Abstract
In this paper we used an approach that applies the improved EVI, NDWI and spatial-gradient analysis, to reduce the mixed information problems and ameliorate extraction technique based on the analysis in multi-spectral remote sensing images and Vegetation Indexes. CBERS-02B CCD image data were used to study the principle and method of quickly extracting the rock-desertification information in Wuchuan County, Guizhou Province. 186 out of 203 sites were verified as rock desertification sites by field work. The results show that 12 sites were misclassified, 5 unclassified, and the overall accuracy is 91.8%.
