摘　　要：近年来洞庭湖区洪涝灾害的频发,使洞庭湖湿地生态脆弱带区域受到越来越多的关注。文章建立了湿地生态脆弱性评价指标体系和方法,并利用该方法对洞庭湖区湿地进行了评价,依据湿地生态特性及演化规律建立评价指标体系,利用层次分析法(AHP)确定指标权重,利用综合指数法计算湿地的脆弱度,为保护洞庭湖区湿地环境,合理开发、利用湿地资源提供了依据。Frequent flood hazards in the Dongting Lake attached more focus on the transitional zone ot the Dongting Lake wet/and, this paper presented an index system and a method for valuating the ecological fragility of wetlands. The indexes were chosen according to the properties and the development pattern of wetland ecosystem in Dongting Lake area, the weight values of weighing the relative importance of the indexes were computed by the method of ＂AHP＂（ Analytic Hierarchy Process） and the fragility level was valuated by the method of multi-indexes, All of them provided the gist for protecting the wetland environments and developing and using the wetland resources in Dongting Lake area.
