我国西南岩溶区由于本身生态环境的脆弱性和人类社会经济活动的频繁性，造成了较为严重的石漠化和水土流失问题，通过黔西高原山地安龙县淌淌河小流域遥感数据处理，构建石漠化等级和水土流失等级分类方法，进行石漠化和水土流失对应关系的探究，结果显示出石漠化与水土流失存在着一定的空间关系，石漠化在时间上晚于水土流失出现，在治理石漠化过程中注重水土流失的防范与治理。

Due to the fragility of ecological environment and the frequency of human social and economic activities, karst areas in Southwest China have caused serious problems of rocky desertification and soil erosion. Based on the remote sensing data processing of Tangtang small watershed in Anlong county of Western Guizhou Plateau, the classification method of rocky desertification grade and soil erosion grade is constructed, and the corresponding relationship between rocky desertification and soil erosion is explored. The results show that there is a certain spatial relationship between rocky desertification and soil erosion. Rocky desertification appears later than soil erosion in time. In the process of controlling rocky desertification, we should pay attention to the prevention and control of soil erosion.
