摘　　要：在分析该项目区水土流失特点及其防治措施布设的基础上,对水土保持防治措施的基础效益、生态效益、社会效益和经济效益进行了分析计算。结果表明;水土保持总治理面积达7766.118hm^2,占建设中开挖、扰动、埋压等毁坏原地貌面积8453.377hm^2的91.9％;整治土地1638.33hm^2,复垦417.5hm^2,土地利用率由原来的42.0％提高到48.6％;各类工程措施拦渣量占总弃渣量的97.6％;控制新增水土流失量占预测流失量的91.6％。It analyzes the basic benefit, ecological benefit, social benefit and economic benefit based on the study of the details of soil loss and the distributing of soil control measures. The results indicates that the total controlled area reached 7 766.118 hm2, which account for 91. 9% of whole disturbed area i. e. 8 453. 377 hm2, the area treated reached 1 638. 33 hm2 and 417. 5 hm2 replanted, the land use increased from 42. 0% to 48. 6%, there 97. 6% of total waste slag was restrained* 91. 6% of forecasted soil loss was under control.
