摘要
湿地是地球上水陆相互作用形成的独特生态系统,对湿地生态系统健康评价,将为生态系统健康诊断和生态修复提供决策依据。充分考虑石臼湖湿地的实际情况,从湿地生态特征,功能整合性和社会经济环境等三方面共选取24项评价指标,建立评价指标体系;分别对石臼湖湿地的生态特征(湿地土壤、植被、水环境质量、生物多样性等)、生态功能(物质生产与生物多样性维持功能、水调节及水质净化功能等)进行了逐项具体分析与评价;然后运用模糊综合评价法及对数模型分别对石臼湖湿地生态系统健康状况进行了综合分析,并对两种评价方法进行了比较分析。最后,在评价分析的基础上,针对石臼湖湿地生态系统存在的问题提出了湿地恢复的对策及恢复方案。
Wetland,a unique ecosystem on Earth,is the most import ecological environment for the survival of human beings.The wetland eco-health assessment provides a decision-making basis for ecosystem health diagnosis and ecological restoration.Fully considering the basic status of Shijiu lake wetland,the 24 indices were selected to assess the health of the wetland ecosystem from the ecological character,unitary function and the society-economy environment of the wetland in this paper.The weight for each index was calculated by referring to the opinion of experts.By the model of fuzzy comprehensive evaluation and the model of log-linear,the status of wetland ecosystem health in Shijiu Lake was analyzed respectively and the two models were compared.Finally,the renewal measures of Shijiu lake wetland were put forward according to the evaluation results.
