基于AHP的丹江流域生态修复模式模糊综合评价

Fuzzy comprehensive evaluation on ecological restoration modes in Danjiang River basin based on AHP

丹江流域过去几十年里采用了生态、工程、生态与工程相结合、生态移民4种模式对流域生态进行了修复。为了进一步完善丹江流域生态修复模式,建立了生态修复评价指标体系,采用层次分析法和模糊综合评判法对丹江流域生态修复的综合效果进行了评价。丹江流域生态修复评价结果为良好。经分析发现,丹江流域生态修复中植物措施的主导地位没有得到充分体现,而工程措施比较多,今后,应以自然修复模式为主,人为工程修复模式为辅。

In the past several decades, 4 modes of basin ecological restoration were adopted in Danjiang River basin, including ecological mode, structural mode, combination of ecological and structural mode, and the ecological migration mode. In order to further perfect basin ecological mode, an assessment index system for ecological restoration mode is established and the compre- hensive restoration effect of Danjiang River basin is assessed by AHP and Fuzzy Comprehensive Evaluation Method. The assessment result of Danjiang River basin is good. The analysis discovers that the dominate role of plant restoration measure in ecological restoration has not been fully played, while structure measure is mainly applied. In the future, the natural restoration mode should be applied as the main measure in the ecological restoration, assisted by the artificial mode.
