| Abstract: | Using the new theory and technique of the economic valuation of environment (including market Valuation
technique, shadow engineering technique, etc. ) ,the authors in this paper calculated.quantitatively the direct economic loss of Soil erosion (including slopeland surface erosion and gravitational erosion) in Jinsha River Basin of Yunnan Province, which includes three parts, i. e. Readily available nutrient loss, water loss and sediment loss. In addition, the paper analysed the regional characteristics of direct economic loss of soil erosion in the Basin. The study may provide scientific bases for mapping, out the planning of preventing and controlling soil erosion and the measures of disaster reduction in the light of local conditions. |
