摘　　要：运用AHP方法,选取13项敏感因子建立北疆地区生态脆弱性评价指标体系并确定了各指标权重;结合AHP和模糊综合评判法,计算了8个地州对各项评价指标的综合隶属度;根据隶属度大小,对生态脆弱性程度分级,得到北疆8个地州的生态脆弱性分级图;最后,分析了各地州生态脆弱性成因和发展对策.计算结果与相关文献记录数据一致,证明该方法兼具2种方法的优点,适用于生态脆弱性评价.本文研究成果也能为北疆地区制定发展策略提供一定的理论依据.Based on the method of AHP,13 sensitive factors are selected to construct ecological fragility assessment index for 8 autonomous prefectures in northern Xinjiang,with their relative weights calculated.Comprehensive feudatory degrees for each autonomous prefecture are acquired by fuzzy integrated evaluation.Ecological fragility gradation map was obtained from ecological fragility level for each autonomous prefecture,being divided into 4 grades according to comprehensive feudatory degrees.Causes for ecological fragility in each autonomous prefecture are analyzed,corresponding development strategies are proposed.Since the final results are quite similar to previous reports,it is concluded that integrating AHP and fuzzy integrated evaluation will probably be very useful for ecological fragility assessment.These data could provide more theoretical foundation for strategy development.
