摘要
以2014—2015年双台子河口滨海湿地植被修复20个站位调查资料为基础,对湿地修复结构指标、功能指标和环境指标进行研究,结合湿地生态系统健康理论,构建湿地生态环境健康评价指标体系。运用层次分析法(AHP)确定权重,对各个指标赋予权重,将健康评价分为3个等级,确立了生态健康评价方法,对近岸破损湿地翅碱蓬修复生境进行评价。进一步引用评价净影响值(EI)方法判断生境修复前、后的健康对比状态,从而确定翅碱蓬对该破损湿地的修复效果显著。从景观生态学和健康评价角度分析来看,建立此评价方法是可行的,可为今后湿地的管理与保护提供科学依据。
Based on data from 20 stations in coastal wetland plant restoration zone near Panjin Shuangtaizi Estuary,the structure index,function index and environmental index were studied. Combining the theories of wetland ecosystem health,the wetland ecosystem health assessment index system was established. The analytic hierarchy process（AHP） was used to determine the weight of index system and establish ecosystem health assessment method,which could be divided into 3 levels.The effect of suaedaon repairing offshor damaged wetland was then discussed. In addition,the article further referred to the method of net environmental impact value（EI） to evaluate the health status before and after habitat restoration,so that the effect of suaedaon on the reparation of the damaged wetlands was remarkable. From the perspective of landscape ecology and environment health evaluation,the method was feasible,which could provide scientific basis for protection and management of wetlands in the future.
