重要水库水源地生态服务价值评估——以株树桥水库为例

Assessment on Ecological Service Value of Important Reservoir-type Water Sources——Taking Zhushuqiao Reservoir for Example

以长沙市重要饮用水水源地株树桥水库水源地为研究对象,采用基于单位面积价值当量因子和中间物质转换价值量,评估研究区域生态服务总价值,计算出株树桥水库水源地生态服务总价值分别为44.49亿、76.69亿元/a,通过比较2种评估方法的计算结果,提出提升和改善水库水源地生态服务价值的措施,为水库水源地的生态补偿机制优化、生态保护、经济建设等提供参考。

This paper takes Zhushuqiao Reservoir,an important drinking water source in Changsha City as the research object,estimates and calculates that the total ecological service value of Zhushuqiao Reservoir is 4.449 billion yuan per area and 7.669 billion yuan per area respectively by the methods of value equivalent factor per unit area and intermediate substance conversion value,and proposes,measures to enhance the ecological service value of reservoir-type water sources by comparing different calculating results from the two methods,which can provide reference for ecological compensation mechanism improvement,ecological protection and economic development,etc.
