| 摘 要： | 以京津水源区的西北沟流域为研究对象,应用环境经济学原理选取土地损失、土壤肥力损失、泥沙淤积损失、富营养化损失作为衡量土壤侵蚀经济损失的指标,估算出该流域每年流失土壤3.37万t,损失耕地8.64 hm2,每年因土壤侵蚀造成的经济损失为56.67万元,其中N、P、K养分损失20.72万元,占土壤侵蚀总损失量的36.56%。

| Abstract: | The paper selected land loss,loss of soil fertility,sedimentation loss and eutrophication loss as the index for judging the economic loss of soil erosion by using the principles of environmental economics by taking Xibeigou small watershed which is located in the water source area of Beijing and Tianjin as an object of study.It calculated that the annual soil loss of the watershed was 33 700 t,farmland loss 8.64 hm2 and the annual economic loss caused by soil erosion was 566 700 Yuan,of which,N,P and K nutrient losses 207 200 Yuan,making up 36.56% of the total loss of soil erosion. |
