Abstract
Karst rocky desertification is a geo-ecological problem in Southwest China. Preventing and controlling rocky desertification has become critical. So,the Longhe,Pingguo,Guangxi Province in southwestern china, a typical serious rocky desertification area, were selected as the study area. After investigation and researches to the environments and regional economics in detail, the stereo eco-agriculture in different geomorphologic position of the peak -cluster depression has been built and was considered as an available model for the comprehensive improvement to rocky desertification. For about four years, the comprehensive improvement of rocky desertification in the experimental area has achieved good results. The vegetation is gradually restored, the annual mean income of the local people has increased by about 20%, and the new local ecological industry is formed.
