Abstract：The relationship between the soil erosion and water loss and the eroded landform of granite in southeast of China is studied, and that maybe offer reference of sustainable development in agriculture and environment in the area. The analysis of influence of slope shape, direction and formation of its matter on the modern erosion in granite ancient landform in Hengshan mountain showed that the ancient landform is the basic factor of the production and development of modern erosion. When little disturbance of human activities was, modern erosion must be natural erosion. But if the vegetation is destroyed, then the accelerating erosion may take place. Meanwhile the modern erosion reshape the landform, affecting the formation and development of rock, gully slope collapse and slope vale landform. Single planted vegetation decreases the soil erosion at certain extent and stabilizes the development of landform, but far off the mixed vegetation of nature formation.
