摘　　要：依据生态健康的涵义,针对三峡库区脆弱生态典型区生态影响因素的不确定性和模糊性,将熵值理论与模糊理论相结合,构建了基于熵权与模糊层次分析法的组合权重多层次评价指标体系及指标计量模型,并评价了三峡脆弱生态典型区生态系统的健康,为三峡库区生态规划与保护提供了科学依据。According to the meaning of ecological health and the complexity and the fuzziness of typical fragile ecological area in Three Gorges,the entropy value theory combined with fuzzy theory is applied to establish multi-level indicators of ecosystem health assessment and its quantitative model based on FAHP and entropy weight.Taking the Three Gorges reservoir area for an example,it evaluates their ecological health,which provides a scientific basis for programming and protecting ecology of Three Gorges reservoi...
