摘要：湿地生态环境质量评价研究对湿地管理具有重要的意义。以衡水湖湿地作为评价对象,采用驱动力-压力-状态-影响-响应(driving-pressure-state-impact-response,DPSIR)模型,筛选出15个指标,构建了湿地生态环境质量评价指标体系,得到各指标的隶属度矩阵;应用模糊综合评价法,对衡水湖湿地的生态环境质量进行评价。研究结果表明,衡水湖湿地生态环境质量综合评价指数为0.663 9,处于Ⅱ级(较好),即该湿地生态环境质量状况较好;从项目层面来看,驱动力层、压力层、状态层、影响层和响应层的生态环境质量分别处于Ⅲ级(一般)、Ⅰ级(很好)、Ⅲ级(一般)、Ⅱ级(较好)和Ⅰ级(很好);对衡水湖湿地生态环境质量产生负面影响的要素主要为衡水湖水体中的总氮含量和周围空气负离子含量。
The evaluation on ecological environment quality of the wetlands is of great significance to wetland management.Taking Hengshui Lake wetlands as the evaluation object,the driving-pressure-state-impactresponse(DPSIR)model was used,15 indicators were selected,and the evaluation index system was constructed,and then the membership degree matrix of each index was obtained.The ecological environment quality of Hengshui Lake wetlands was evaluated by fuzzy comprehensive evaluation method.Then the results showed that the comprehensive evaluation index of ecological environment quality of Hengshui Lake wetlands was 0.663 9,which was in gradeⅡ(better),and the ecological environment quality of the wetlands was good.At the project level,the ecological environment quality of the driving,pressure,state,impact and response layers were at grade III(generic),I(best),III(generic),II(better)and I(best),respectively.The main factors that have a negative impact on the ecological environment quality of Hengshui Lake wetlands were the total nitrogen content and the negative air ion concentration.
