上海崇明县湿地生态系统服务功能价值评价

Reevaluation of the value of wetland ecosystem services in Chongming County,Shanghai

【目的】对崇明县湿地生态系统服务功能价值进行核算,一方面为湿地生态系统生态价值核算提供参考依据,另一方面可以为崇明县湿地保护、恢复与可持续发展提供指导。【方法】基于上海市第2次(2011—2013年)湿地资源调查数据,将崇明县湿地划分为3类10型;根据《千年生态系统评估》,结合崇明县实际,将崇明县湿地生态系统服务功能分为4大类共13项,并估算了崇明县湿地的价值。【结果】崇明县湿地生态系统服务功能总价值为124.13亿元。在各湿地类型中,近海与海岸湿地的服务功能价值最大为5153亿元,其次是人工湿地的服务功能价值为24.74亿元,沼泽湿地的服务价值最小仅为2.61亿元;湿地生态系统的各项服务功能价值大小顺序为:调节服务价值(48.25亿元)>支持服务价值(43.81亿元)>供给服务价值(22.57亿元)>文化服务价值(9.50亿元)。【结论】调节服务和支持服务是崇明县湿地生态系统的主导服务功能,因此,在坚持优先保护的原则下,合理高效利用湿地资源,可提高该县湿地服务总价值量。

[ Objective] Estimating the value of wetland ecosystem services can provide guidance for the protection, resto- ration and sustainable development of wetland and be used as a reference for the ecological value accounting in Chongming County. [ Method] Based on the second Shanghai wetland survey （2011-2013） , wetlands in Chongrning County were clas- sified as three categories including 10 types in total. Wetland ecosystem sePdees were divided into 4 types including 13 ma- jor evaluation parameters according to the Millennium Ecosystem Assessment. [ Result] The total value of wetland ecosystem services was evaluated to be 12. 413 billion Yuan. Among various type of wetlands, coastal wetlands had the greatest value of 5. 153 billion Yuan. Artificial wetlands and marsh had 2. 474 and 0. 261 billion Yuan, respectively. Regulating services （4. 825 billion Yuan） and supporting services （4. 381 billion Yuan） were the major wetland ecosystem service compared to the provisioning services （ 2. 257 billion Yuan） and cultural services （ 0. 950 billion Yuan） in Chongming. [ Conclusion ] Therefore, rational and efficient utilization of wetland resources could increase the total value of wetland ecosystem services under the principle of priority protection.
