| Abstract: | This paper deals with the application of the image data of TM7, TM5, TM3 Bands from Landsat-5 to the comprehensive analysis of the distribution and formation conditions of karst stone desertization in Guangxi. In view of the serious karst stone desertization developed in Pingguo and Dahua Counties, the authors used different TM images in different periods to make comparison, thus finding out the causes responsible for the withering of karst stone desertization. Based on summarizing the regulation of stone desertization, the paper also discusses the division of the intensity of stone desertization. |
