摘要
利用美国Landsat-5TM7、TM5、TM3波段假彩色合成图像,对广西岩溶石漠化分布特征和形成条件进行遥感综合分析。结合石漠化发育严重的平果和大化县,用不同时相的TM图像进行对比,查明岩溶石漠化的萎缩原因。在总结石漠化变化规律的基础上,对石漠化强弱程度的划分进行了探讨。
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.
