摘　　要：以广西典型石漠化区的平果县为研究区,基于2005～2007年时间段的高分辨率TM/ETM数据,采用石漠化指数模型和石漠化解译分级标准调查研究研究区石漠化空间分布概况。结果表明:研究区石漠化空间分布状况遥感解译结果与实地调查情况基本吻合。Taking Pingguo county as Guangxi typical desertification study area,using high-resolution TM/ETM data during 2005-2007,with rocky index model and the interpretation of classification stan-dards,spatial distribution of desertification of the study area was studied.The results showed that the spatial distribution of desertification RS interpretation and field survey results are basically similar.
