摘　　要：采用样方法对泉州湾河口湿地自然保护区桐花树(Aegiceras corniculatum)进行群落调查,了解其群落特征;并通过野外实验、收集资料、调查法等方式获得基础数据,运用生态经济学方法,对桐花树生态系统的气体调节功能、物质生产功能、净化功能、土壤保持功能、旅游功能和生物多样性保持功能等进行生态系统服务功能价值评估.结果表明,泉州湾自然保护区桐花树林生态系统服务功能总价值高达每年5 828.4万元,单位面积价值达到13.39万元.(hm2.a)-1,其中侵蚀控制和沉积物保持的价值3 690万元.a-1,占总价值的比例最高.A community survey was made to understand community characteristic of Aegiceras cornicalarum in Quanzhou Bay Estuary Wetland Nature Reserve by using quadrat method.In order to assess the characteristic of ecosystem,the basic data were obtained through field experiments,literature studies and investigations.The functions such as air purification,material production,climate regulation,soil conservation,tourism and biodiversity conservation of Aegiceras cornicalarum ecosystem were valuated by the ecological economic methods including the direct market approach,cost method,carbon tax method,asset value appraise,ecological value method and substitution method.Evaluation results show that ecological value of Aegiceras corniculatum ecosystem services in Quanzhou Bay Nature Reserves valued at up to 58.284 million yuan per year,and 133,900 yuan（hm2·a）-1.The highest proportion of the total value is the service valuation of erosion control and sediment retention,and this value is 36.9 million yuan per year,which clearly highlights Aegiceras corniculatum as a ＂coast guard＂ feature.
