摘　　要：选取林草植被恢复率、林草覆盖度、治理措施合格率、拦渣率、土壤侵蚀减少率、土壤流失控制比、河流含沙量、水土流失治理度、扰动土地整治率等9项与水土流失防治效果紧密相关的评价指标,构建了金安桥水电站工程水土流失防治效果评价的指标体系。用层次分析法和综合指数法,对金安桥水电站工程水土流失防治效果进行评价。结果表明,金安桥水电站工程水土流失防治效果处于5个评价等级(极差、较差、一般、良好、优良)的"一般"等级,存在着林草恢复率和林草覆盖度偏低、河流含沙量较大等问题。该评价结果,可为金安桥水电站工程水土流失控制措施的进一步完善提供依据,为类似工程的水土保持评价研究工作提供借鉴。The indexes of vegetation restoration degree,vegetation coverage,qualified control measurement rate,dreg blocking rate,reduced soil erosion rate,soil and water loss control ratio,sediment concentration,soil and water loss control degree,and disturbed land remediation rate are significant in the evaluation of soil erosion control effect.The 9 evaluation indexes are thus selected to construct an index system using the method of analytic hierarchy process and synthetic index method for the evaluation of soil loss control effect in Jinanqiao hydropower station project.In the five levels of very poor,poor,general,good,and very good,soil loss control effect in the project is in the ＂general＂ level,being low in vegetation restoration degree and low coverage,but high in sediment concentration.Result from the evaluation can provide further improvement in soil erosion control measurements of the hydropower station and a reference to similar research works.
