在利用RUSLE模型估算安徽省土壤侵蚀量的基础上,利用环境经济学基本原理和方法,选取N、P、K及有机质等养分,水分损失,泥沙滞留、泥沙淤积等实物型损失作为衡量土壤侵蚀经济损失的指标,采用替代价格法、影子工程法和机会成本法估算出安徽省土壤侵蚀的经济损失的货币化结果。结果显示:2000年安徽省土壤侵蚀经济损失总量达到173081.97万元,其中养分流失引起的损失是安徽省水土流失经济损失的主要形式,达到了90.41%;安徽省土壤侵蚀经济损失在空间上呈现南高北低的趋势。
Based on the use of the RUSLE model to estimate the amount of soil erosion in Anhui Province, the basic principles and methods of environmental economics were used to select physical losses such as N, P, K, organic matter, water loss, sediment retention and sedimentation as measures An indicator of the economic loss of soil erosion, the monetization result of the economic loss of soil erosion in Anhui Province was estimated by the method of substitution price, shadow engineering and opportunity cost. The results showed that the total economic loss of soil erosion in Anhui Province in 2000 reached 1,730,819,700 yuan, of which the loss caused by nutrient loss was the main form of economic loss of soil and water loss in Anhui Province, reaching 90.41%. The economic loss of soil erosion in Anhui Province was spatially presented South high North low trend.
