摘　　要：本文以广西河池地区为研究对象,尝试应用各种遥感研究方法,分析研究岩溶石漠化现状和发展趋势。研究中分别利用1973年MSS数据、1990/1994年TM数据、1999年ETM+数据,通过不同年代数据的对比分析,分别运用NDVI、缨帽变换绿度指数、掩模分区、基于岩溶石漠化植被指数和主成分分析的信息提取方法等四种研究方法,对研究区进行定量测度,以分析其岩溶石漠化现状及发展趋势。通过研究发现,四种研究方法的作用各有特点、各有所长、相辅相成,可根据实际需要选取其中的方法应用到岩溶石漠化的研究和监测中。This paper takes Hechi of Guangxi area as the research object, using the 1973 MSS data, 1990/1994 TM data and ETM＋ data in 1999, by comparing the different in data analysis, using the four methods of NDVI vegetation index, vegetation index, tasseled cap transformation mask division, information extraction method analysis of karst rocky desertification and vegetation index based on principal components respectively, quantitative analysis of the current situation and development trend of the research area of karst rocky desertifcation. The study found that the four methods have their own characteristics and function, can be selected according to each one has his good points complement each other, which method could be applied to the research and monitoring of Karst Rocky Desertifcation in the actual needs.
