Abstract:

Rocky desertification in Karst areas of southwestern China is an prominent regional environmental problem and hot research spot. This paper analyzed the research advance of Karst rocky desertification, including the formation reasons and the environment evaluation system, and reviewed the comprehensive recovery progress on Karst rocky desertificafion with the state forestry ecoengineering recently. We proposed the research orientation of rocky desertification in southwest China in the future, which was referred to study on formation mechanism of rocky desertification, the principle of restoring vegetation, and the application of the remote sensing technology to supply the principle for the comprehensive eco restoration of rocky desertification.

Key words: southwestern China, Karst area, rocky desertification situation, formation mechanism, treatment advancement, eco restoration countermeasure
