摘要

Abstract-Based on the karst ecological system vulnerability characteristics , a case in Qiannan of Guizhou Province, BuYiZu and Miao Minority Autonomous Prefecture, we referenced RUSLE model ,and introduced rock as one of the factors that influence, analyzed soil erosion risk of qiannan autonomous prefecture under the support of RS and GIS. The result indicates: The area of not dangerous is 7875.41 km2, accounting for 30.07% of the total area. In the karst area of special geographical conditions, the sole erosion risk is higher, and karst ecological system is vulnerable. In the future, water and soil conservation experts should focus on high soil erosion risk areas in order to create effectivepreventive measures.
