Soil Erosion and Ecologic Problem in Hengyang Red Rock Basin

This paper probed into the intensity,type,evolution,distribution and mechanism of soil erosion in Hengyang red rock basin in Hunan Province. In the light of abnormality of inorganic eco-logic factors and imbalance of organic ecologic factors etc. dut to soil erosion, strategies for prevention and harnessment of soil loss were put forward such as controlling the growth of population and developing the economy; afforesting and planting grass to recover vegetation; setting up relevant projects to conserve soil and water and so on.
