- Abstract:
- Unreasonable land use pattern is the main cause leading to soil erosion.It is important to evaluate soil erosion in the Dianchi Lake watershed for the purpose of preventing soil and water from loss,controlling environmental deterioration,and establishing good ecological environment.We conducted soil erosion research in the Dianchi Lake watershed by using RS/GIS and USLE model.Impacts of different slope and vegetation types on soil erosion were discussed.And the way to calculate C factor based on vegetation coverage was proposed.The results indicated that the total rate of soil erosion was 2.339 6 million tons.Most of soil erosion occurred at mild and moderate degree.And heavy soil erosion area was few.Soil erosion mainly occurred in the region of the slope from 8 °to 35°.Soil erosion modulus was the largest in shrublands.The quantitative assessment by USLE model could indicate the soil erosion efficiently and objectively with the support of GIS.It was an extremely important reference for reducing soil erosion and controlling non-point source pollution.
