摘　　要：为探索泥炭沼泽生态系统服务功能价值,以福建天宝岩国家级自然保护区水竹(Phyllostachys heteroclada)沼泽、垂穗石松(Palhinhaea cernua)沼泽、灯芯草(Juncus effusus)沼泽和泥炭藓(Sphagnum magellanicum)沼泽4种典型泥炭沼泽生态系统为研究对象,应用能值理论,构建了泥炭沼泽生态系统服务价值评价体系,评估天宝岩不同类型泥炭沼泽生态系统服务价值。结果表明:(1)泥炭沼泽生态系统服务总能值为1.01×1019sej·a^(-1),宏观经济价值约为9.99×10^(6)元·a^(-1),其中直接服务能值为5.45×10^(17)sej·a^(-1),经济价值为5.36×10^(5)元·a^(-1);间接服务能值为2.73×10^(18)sej·a^(-1),经济价值为2.69×10^(6)元·a^(-1);存在服务能值为6.86×10^(18)sej·a^(-1),经济价值为6.76×10^(6)元·a^(-1);(2)单位面积泥炭沼泽生态系统服务价值大小顺序为泥炭藓沼泽>灯芯草沼泽>垂穗石松沼泽>水竹沼泽;(3)各项服务功能价值大小顺序为文化科研(60.28%)>净化水质(27.03%)>维持生物多样性(6.65%)>增加生物量(4.27%)>增加NPP(0.81%)>涵养水源(0.74%)>储蓄泥炭(0.39%)>固碳释氧(0.16%)。研究结果可为泥炭沼泽湿地生态补偿与差异化保护提供理论支撑。To assess the values of ecosystem services provided by peat swamp habitats,four typical peat swamp ecosystems(Phyllostachys heteroclada peat swamp,Palhinhaea cernua peat swamp,Juncus effusus peat swamp,and Sphagnum magellanicum peat swamp)were selected in the Tianbaoyan National Nature Reserve(TNNR)in Fujian Province.Using the emergy theory,an evaluation system for the peat swamp ecosystem service values was established,and the service values of the different types of peat swamp ecosystems in TNNR were assessed.The results show that:(1)The total emergy of peat swamp ecosystem services in TNNR was 1.01×1019sej·a^(-1),with a macroeconomic value of 9.99×10~6 yuan·a^(-1).The direct service emergy value was 5.45×10^(17)sej·a^(-1),worth 5.36×10^(5) yuan·a^(-1);the indirect service emergy value was 2.73×10^(18)sej·a^(-1),worth 2.69×10~6 yuan·a^(-1);the existing service emergy value was 6.86×10^(18)sej·a^(-1),worth 6.76×10^(6) yuan·a^(-1).(2)The order of peat swamp ecosystem service value per unit area was Sphagnum magellanicum peat swamp>Juncus effusus peat swamp>Palhinhaea cernua peat swamp>Phyllostachys heteroclada peat swamp.(3)The order of the value of each service function was culture&research(60.28%)>water purification(27.03%)>biodiversity maintenance(6.65%)>biomass increase(4.27%)>NPP increase(0.81%)>water conservation(0.74%)>peat storage(0.39%)>carbon fixation and oxygen release(0.16%).These findings provide theoretical support for the ecological compensation and differentiated protection of peat swamp wetlands.
