The area of Karst landform is about 300 000 km^2 , and occupies more than 3 % of the total land area of China, in which half of the Karst regions have been desertificated. The rocky desertification area is outspreading by the rate of 2 500 km^2 per year. Rocky desertification is seriously threatening the survival, productive activities and livelihood of local people. It is a serious problem in south China. This paper reviews the forming causes of rocky desertification and its hazard, and proposes some constructive preventive strategies and advices. |
