针对水电工程环境影响评价体系中各指标间相互影响的特点, 将网络层次分析法( ANP) 和模糊综合评价法 ( FCE)相结合, 对水电工程环境影响进行综合评价。首先根据网络层次分析法( ANP) 构建水电工程环境影响评价 的网络结构模型, 确定所有评价指标的权重, 该方法克服了以往运用层次分析法( AHP)确定指标权重不能反映指 标之间相互影响关系的弊端; 然后引入模糊综合评价( FCE)的思想和方法对水电工程环境影响进行评价, 提出水电 工程环境影响评价的 ANP2FCE 模型。对我国北方某水电工程进行实例分析的结果显示, 该评价模型合理、 有效。

T here is interaction between each index in the environmental impact assessment system of the hydropower project. An2 alytic network process( ANP) and fuzzy comprehensive evaluation( FCE) were used to perform the comprehensive evaluation of the environmental impact of hydropower project. First, the network structure model for the environmental impact assessment of hydropower project was developed based on ANP and the weights of all evaluation indexes were determined. T his method over2 comes the disadvantage of not reflecting the interaction between the indexes using the analytic hierarchy process( AHP) . T hen, the theory and method of FCE were introduced to perform the environmental impact assessment of hydropower project, and the ANP2FCE model to evaluate environmental impact of hydropower project was proposed. Finally, the model was applied to a hy2 dropower project in north China and the results suggested the evaluation model is reasonable and effective.
