摘要
应用环境经济评价理论与方法,定量地测算了云南金沙江流域水土流失(包括坡面侵蚀和重力侵蚀2个方 面)的直接经济损失,包括养分流失损失、水分流失损失和泥沙流失损失3项内容,并分析了水土流失直接经济损失 的区域特征,为该流域水土流失防治提供了基础依据。
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...
