Yunnan is located in the center of the east-Asian karst area,one of the three largest karst areas in the world.Rocky desertification is widespread in the area,which seriously restricts the sustainable development of local social economy.In this study,we summarize the research status and achievements of rocky desertification in Yunnan mainly from three aspects,rocky desertification zoning,governance model and vegetation restoration in rocky desertification areas.The results show that rocky desertification areas in Yunnan are divided into 2 large areas and 5 small ones.After years of exploration,23 kinds in 4 categories of rocky desertification control models have been formed,and 435 kinds of plant species can be used for ecological restoration in rocky desertification areas,including 376 species of shrubs and 59 species of herbs.Finally,combined with geographical location,climate and altitude,this paper preliminarily summarizes the suitable restoration vegetation,and points out the shortcomings in the studies on the control of rocky desertification,so as to provide an important theoretical reference for the subsequent research on the restoration and control of rocky desertification vegetation.
