摘　　要：根据工程扰动边坡的水土保持植被工程效果和评价指标选取原则，将水土保持效果及植被工程效果两方面作为标准，选取了6个与评价目标紧密相关的评价指标，建立了水土保持植被工程效果评价体系。分别选择了向家坝水电站4个不同植被工程措施的边坡，采用层次分析法确定出评价指标体系中各指标的权重，然后结合综合指数计算模型得到4个不同边坡的水土保持植被工程效果的综合评价值。结果表明：各个植被工程的综合评价值为植被混凝土（0．9174）〉厚层基材（0．8681）〉框格梁（0．6874）〉弃渣地（0．0921），评价结果与样地边坡实际情况一致。表明所构建的指标体系可以较好地应用于水土保持植被工程效果的评价，为工程扰动边坡水土保持植被工程效果的定量分析提供了可行的方法。According to the effect of the engineering of vegetation for soil and water conservation and the selecting principle of evaluation index, and regarding the effect of soil and water conservation and the effect of vegetation construction as the standards, six evalua- tion indexes closely related with the evaluation objectives are selected to build the valuation system of vegetation engineering for soil and water conservation effect. Four different vegetation engineering measures are selected in Xiangjiaba hydropower station, and four dif- ferent composite indexes of soil and water conservation effect of slope vegetation engineering are achieved by using analytic hierarchy process to determine the evaluation index systern in each index weights. each project is vegetation--The results show that growing concrete base the comprehensive material （0. 9174） 〉evaluation value of thick layer base material（0. 8681）〉 Frame Beams （0. 6874） 〉 Spoil Ground （0.0921） ,and the evaluation results are consistent with the actual situation of the slope plot. It shows that the construc- ted system can be better applied to the evaluation of the effect of soil and water conservation vegetation engineering, and it provides a feasible method for the quantification analysis of the construction perturbed slope of soil and water conservation vegetation engineering.
