巢湖流域水土流失的环境经济损失研究

本文首先对水土流失经济损失的国内外研究现状进行了总结概述。在此基础上,以巢湖流域为例,针对流域特点及水土流失状况,确定水土流失造成的养分损失、泥沙淤积损失、水分损失及耕地损失四项实物型损失量作为衡量水土流失环境经济损失的指标,选用替代花费法、恢复费用法及影子工程法等对水土流失的经济损失进行了评估和货币化计量。

Research on Environmental Economic Costs of Soil Erosion in Chaohu Basin

Based on the summarize of the research state of economic costs of soil erosion both home and overseas,five kinds of material loss brought by soil erosion,including nutrition,soil and silt,water and plantation loss,are chose as the index to measure the economic costs of soil erosion illustrated with Chaohu basin.Substitute expense method,recovery cost method and shadow engineering method are used to evaluate and estimate the costs.
