摘　　要：以洞庭湖流域水生态系统为例,在明确河湖库塘生态系统服务功能内涵的基础上,运用生态学与生态经济学方法对洞庭湖流域各类水生态系统服务功能经济价值进行了评估。结果表明,全流域河湖库塘水生态系统服务功能总价值量为1106.19亿元,约占湖南省2004年GDP(5612.26亿元)的19.7%,其中,城镇和农村生活供水、工农业生产供水、水力发电、内陆航运等直接利用价值为415.698亿元;调洪、输沙、水资源贮存等间接利用价值为690.492亿元。可以认为,流域水生态系统服务功能对湖南省工农业生产的持续发展,维系生态环境健康和人民生命财产安全起到了不可替代的支撑和保障作用。By using the method of bionomics and ecological economics, the economic values of all kinds of freshwater ecosystem service function in the Dongting Lake basin are evaluated. The results indicate that the total ecosystem service value of the river-lake-reservoir-pond in the basin is more than 110.62× 10^9 Yuan, accounting for 19.7 percent of the 2004 GDP of Hunan Province, in which the direct value, including water supply for people living and industrial-agricultural production, hydroelectricity generating, shipping, and so on, amounts to 41.57 × 10^9yuan, while indirect value, including adjusting floods, carrying sand, storing water resource, and so on , 69.05 × 10^9 Yuan. So, freshwater ecosystem services in the basin exert an indispensable function to support and safeguard the sustainable development of agriculture and industry in Hunan, maintain the whole ecosystems health and people＇ s life and wealth safety.
