【摘要】 滨海新区湿地类型多样,作为滨海新区生态环境与景观生态的基质,对其区域生态、景观生态及经济发展具有重要影响。根据滨海新区湿地生态系统特征,在定性与定量相结合的原则下,建立了退化诊断分析指标体系,共两个大类23个单项指标,并通过AHP法、专家咨询法确定了各指标的权重。在此基础上,结合GIS技术将滨海新区湿地划分为11个具体的退化研究区域,并参照诊断标准对各项指标打分,计算各评价区域综合诊断指数,依据综合诊断指数分析了评价区域生态系统退化状况,为今后湿地恢复实践提供指导。更多还原

【Abstract】 There are many wetland types in Binhai New Area.As the ecologic and landscape matrix of Binhai New Area,wetland plays an important role in the regional development,landscape ecology and economical development.According to the characteristics of Binhai New Area wetland,and on the qualitative and quantitative principles,the degradation diagnosis index system is established.The system contains two main types and twenty-three single indexes.The weight of every index is determined through Analytical Hierarchy Process(AHP) and Experts Consultation Method.With the help of GIS technology,the wetlands in Binhai New Area are divided into 11 concrete degradation research areas.According to the index system,the Synthetic diagnose index is calculated and the ecosystem degradation degree of every research area is refined.These conclusions will provide guidance for the wetland restoration work in the future.更多还原
