摘要
在以广西都安瑶族自治县为研究对象 ,以RS与GIS一体化为分析手段 ,首先采用TM影像为背景资料 ,辅以地形图、土地利用图、土壤图、地质图以及GPS实测数据库等相关资料综合分析的基础上 ,建立石漠化分级的遥感影像解译指标体系 ,生成都安县石漠化分级分布图和数字化岩性图 。
Du’an Yao Autonomous County is the typical distributing area of Guangxi karst rocky desertification. The grade indices of rocky desertification are selected by the scientific meaning of karst rocky desertification, then the interpretative symbol system of rocky desertification RS image is established by the landscape characteristics of Du’an karst and its TM image. Relying on RS & GIS means and taking land use map as base map,this paper cames out synthetic analysis on 1999a TM image(126-043)and yields the correlation data including landform, soil, geological map and GPS-database and photo on the spot, and brings forth Du’an rocky desertification grades map and digital lithology map. As viewed from spatial correlation, the inherent connection is illustrated between various level rocky desertification and lithology.
