丹江口水库湿地生态系统服务功能研究

On the service function of Danjiangkou reservoir wetland ecosystem

丹江口水库是亚洲第一大人工淡水湖泊,被称为汉江的天然水位调节器,作为一种特殊的生态系统类型,湿地效益类型多样。依据生态学和经济学原理,在对该生态系统理化指标检测、生物资源调查和实地考察基础上,主要从涵养水源、调蓄洪水、调节气候、降解污染、固定C和释放O2、控制侵蚀、保护土壤、参与营养循环等方面对丹江口水库湿地生态系统服务功能进行了研究,并提出相应的保护对策。

Danjiangkou reservoir is the first largest artificial fresh water lake in Asia, called water level regulator of Hanjiang. As a special ecosystem type, Danjiangkou reservoir wetland has various beneficial types. According to ecological and economical principle, on the basis of investigation of the wetland resources, the wetland ecosystem service functions of Danjiangkou reservoir were researched including store water, regulating river level, adjusting climate, purfying water, soil and air, fixing C and releasing O2 , controlling erosion, protecting soil, nutrition circling. In the end, some countermeasures for the wetland conservation were put forward.
