摘要

通过专家咨询法,选取相应指标构建适合大连湿地的生态系统健康评价体系。根据模糊综合评价模型,利用层次分析法确定指标权重和隶属度,采用模糊综合评价模型,计算湿地功能整合性、生态特征、社会环境隶属度,并计算其健康度为0.4977,属于第Ⅳ等级(0.3～0.5)疾病状态。湿地生态功能已不能满足维持湿地生态系统的需要,湿地生态系统已开始退化,对大连市湿地生态系统作出预警分析。
        Based on the fuzzy comprehensive evaluation model, the index weight and membership degree of the evaluation system for wetland ecosystem were determined by AHP, and the function integration, ecological characteristics and social environment membership were calculated by fuzzy comprehensive evaluation model. The evaluation system was applied to assess the wetland in Dalian. The results showed that the wetland ecological function could not meet the needs of maintaining the wetland ecosystem. It has started to degenerate, and the warning analysis of the wetland ecosystem in Dalian has been conducted.
