摘　　要：从社会、生态、经济3个层面建立水土流失效益综合评估指标体系,并结合层次-熵值组合模型对阜新地区小流域水土流失治理综合效益进行评估。评估结果表明:所建综合评估指标体系客观、合理,评估结果符合实际水土流失治理情况。A comprehensive evaluation index system for soil erosion benefits was established from three levels of society,ecology,and economy,and combined with a hierarchical-entropy combination model to evaluate the comprehensive benefits of soil erosion in Fuxin area.The evaluation results show that the comprehensive evaluation index system constructed is objective and reasonable,and the evaluation results are consistent with the actual soil erosion situation.The research results have important reference value for the comprehensive benefit evaluation of soil erosion control in Liaoning Province.

关 键 词：层次-熵值组合模型 水土流失治理效益 综合评估
