摘要: 以大樟溪流域永泰县生态服务系统为研究对象,确定了生态系统内供水功能价值、供电功能价值、物质产出功能价值、休闲旅游价值、大气调节功能价值、调蓄洪水功能价值、降解污染物功能价值、生物栖息地功能价值8种服务功能价值为评估指标,综合运用市场价值法、旅行费用法、替代市场价值法、影子工程法等方法评估了大樟溪流域永泰县生态系统服务功能价值。研究结果表明:2017年永泰县生态系统服务总价值为149.87亿元,其中物质产出功能价值占比最大,达到了72.78亿元,是该系统的核心功能;评估的8项功能服务价值排序结果为,物质产出功能价值>降解污染物功能价值>调蓄洪水功能价值>大气调节功能价值>生物栖息功能价值>休闲旅游功能价值>供电功能价值>供水功能价值,直观反映了大樟溪对当地的巨大贡献价值。结合当地特色与现状,提出了发展流域生态旅游、提升供电功能价值、提升供水功能价值的建议。

Abstract: This paper determines the function values of Yongtai county ecological system in Dazhangxi river basin in water supply, electrical supply, production, tourism, atmosphere conditioning, water reserve and flood prevention, pollution reduction and biological habitat, and uses market values, travel expense, alternative market values and shade engineering to evaluate its service function values. Its gross service values reach 14.987 billion RMB of Yongtai county ecological system in 2017, of which production contributes the most, up to 7.278 billion, the core function, then followed by pollution reduction, water reserve and flood prevention, atmosphere conditioning, biological habitat, tourism, electrical supply and water supply, in a descending order, showing the contribution of Dazhangxi. This paper presents suggestions on developing river basin ecological tourism, improving electrical and water supply function values based on Dazhangxi's situation and features.
