基于层次分析法的人工湿地生态系统服务价值评估--以龙口泳汶河湿地为例

Ecosystem Service Evaluation of Constructed Wetland Based on AHP—Taking YongWen River Wetland as an Example

龙口市泳汶河生态湿地工程是龙口市为改善泳汶河水生态环境、保持河道生态基流、补充流域地下水而实施的重点项目,但目前仍缺乏针对该湿地能够提供的生态系统服务的评估。通过选取供给服务、调节服务、支持服务、文化服务内的9个生态系统服务评价指标,参照国内广泛应用的层次分析法(AHP)与生态系统服务的计算方法,评估了该生态湿地的生态系统服务能力,为湿地工程设计、建设、运行提供参考。

The Yongwen River ecological wetland project in Longkou City is a key project to improve the ecological environment of Yongwen River,maintain the ecological base flow and replenish the groundwater in the basin.However,the ecosystem service evaluation of Yonwen wetland is still insufficient.This study selects nine ecosystem service evaluating indicators from supply service,regulation service,support service and cultural service,evaluates the ecosystem service capacity of the ecological wetland with analytic hierarchy process(AHP)and ecosystem service methods as a reference for wetland designing,construction and operation.
