城市湿地生态系统服务的空间流转过程研究——以泉州湾河口湿地为例

Spatial Transfer Process of Urban Wetland Ecosystem Services——A Case of Estuarine Wetlands Quanzhou Bay

以泉州湾河口湿地为研究对象,采用能值分析方法,对该湿地生态系统服务价值进行计算,并以此为基础,讨论其生态系统服务的空间流转过程。研究结果表明,泉州湾河口湿地生态系统的能值总投入共计1.225×1021sej,该湿地生态系统服务功能基本完善,以供给服务输出为主,调节服务次之;渔业产出是高投入、高回报的一项经济服务,但能值产出并不全是正面效应。此外,泉州湾河口湿地生态系统服务空间流转是自然因素和社会经济因素共同作用的结果,其生态系统服务的空间流转过程表现为与湿地空间、资源的内在统一性和系统开放性的规律。

Taking estuarine wetland of Quanzhou Bay as a case study, the value of the wetland has been measured by the method of energy analysis, on which the spatial transferring of the ecosystem service has been discussed. The conclusion is that the total input energy of the wetland per year is 1.225×1021sej, basically the ecosystem services of Quanzhou Bay is entire. And the supply services make up the most of the value of the services, the adjustment one ranked the second; fishery is one of the economic service which characterizes high investment with high return, but the output energy is not always bringing about positive impact. Meanwhile, the study also concludes that the spatial transferring of the ecosystem services is the result of the interaction of natural, social and economic factors, the performance of the ecosystem service spatial transferring presents the rules and laws of wetland space, the inner unity of the resources and the openness of the ecosystem.
