Abstract Site classification and vegetation restoration potential evaluation are important for ecology res-toration in rock desertification area. Studying on site factors is a basis for site classification and site evalu-ation. Through fields investigation of site conditions in Shiqiao catchment of Bijie and Huajiang valley,which are typical serious rock desertification areas, using the methods of causative analysis and statistics analysis, the key site factors of serious rock desertification area have been studied. Results show that the rock character and slope character are controlling site factors of serious rock desertification area based on vegetation restoration, which will provide the foundation for site classification and evaluation in the seri-ous rock desertification region.
