Limestone is widely distributed in Guangxi. Karst is well-developed. There are more rock mountains with more sloping lands with thin soil layer scattered. Soil formation is slow. The soil loss tolerance in the limestone area is only 68 T/km²·a, while the preseent soil loss in this region is 100—200T/km²·a, being much higher than soil loss tolerance. Based on the existing conditions in Guangxi, the author sug gested and discussed some water and soil conservation measures including: 1. afforestation; 2: enclosure of the hills for natural afforestation and vegetation recover; 3. construction of stone-bank terraces; 4. increasing application of chemical fertilizers and soil improvement by subsoiling; and 5. establishment of the eco-objective responsibility system.
