江西省丰城市药湖湿地生态服务功能评价研究

Research on the assessment of wetland ecosystem services value of Yaohuwetland parkin Jiangxi province

根据药湖国家湿地公园长期、连续观测数据及多年科研成果,运用能值分析法,从湿地物质产品功能、涵养水源功能、固碳释氧功能、调节气候功能、保护环境功能、生物多样性保护功能、人文功能等七个方面估算了江西省药湖国家湿地公园湿地生态服务功能总价值,结果表明,2014年药湖国家湿地公园湿地生态服务功能总能值3.85×1020sej·a-1,能值货币总价值为353474768元·a-1,平均每公顷价值为138076元·a-1。药湖国家湿地公园湿地生态服务功能价值量大小顺序为:物质产品>保护环境>涵养水源>生物多样性>人文功能>调节气候>固碳释氧。研究结果表明,药湖湿地公园湿地物质产品功能、保护环境功能、涵养水源功能三个功能所占的比重较大,说明药湖动植物资源非常丰富,在保护当地生态环境、涵养水源等方面发挥巨大作用。

According to the scientific data of Yaohu , evaluating the ecosystem service function valuefrom the functions of wetland material products, water conservation, nitrogen fixation and oxygenrelease, regulating climate, protecting the environment, biodiversity protection function and culturalfunction , The results show that the ecosystem service function energy value of 2014 is3.85×1020sej,the currency value is 353474768 yuan, the currency value is 138076 yuan a ahectare. Theorder of ecosystem service function value of Yaohu wetland park is： Material products 〉 environmentalprotection 〉 water conservation 〉 biodiversity protection function 〉 cultural function 〉 regulatingclimate 〉 nitrogen fixation and oxygen release. The results prove that the value of Material products、environmental protection and water conservation is very important,indicates that plant and animalresources are very rich and areimportant to the local ecological environment.
