    摘要:

    [目的]对黄土高原湿地生态系统服务价值进行科学估算,以保障该区域湿地的生态服务功能,为制定区域生态保护和生态补偿政策提供科学支撑。[方法]以陕西省千湖国家湿地公园为研究对象,结合千湖湿地基本数据和其他相关资料,将千湖国家湿地公园生态系统服务功能价值分为直接使用价值和间接使用价值,包括物质生产,气体调节和水源涵养等7项具体的生态系统服务价值;采用市场价值法、影子工程法和碳税法等方法,对各项生态系统服务价值进行估算。[结果]在千湖湿地各项生态功能服务价值中,气体调节服务价值最高,为2.90×108元/a,占总价值的87.5%,其次为科研文化服务价值为1.90×107元/a,占总价值的5.73%,而水质净化价值最低为3.00×105元/a,占总价值的0.09%,单位面积生态服务价值约为7.90×105元/hm2,小于同样位于陕西省的洽川湿地单位面积生态服务价值量。[结论]陕西省千湖国家湿地公园生态系统服务功能总价值约为3.30×108元,间接服务价值约为总价值的90.5%,直接服务价值约为总价值的9.5%。

    Abstract:

    [Objective] The ecological system service value of wetlands in Loess Plateau was evaluated scienti-fically in order to preserve the wetland ecological service, and to formulate a complete ecological conservation and compensation policy in Loess Plateau.[Methods] Based on fundamental data and other relevant data in Qianhu National Wetland Park, Shaanxi Province, direct and indirect usage values, including air regulation, water storage and retention and others 7 items of ecosystem service values were divided into estimated by methods of market-price, shadow-price and carbon tax, and so on.[Results] Among all the ecological system service values, air regulation service had the highest value which accounted for 87.5% of total ecological system service value; followed by cultural use, which accounted for 5.73% of total service value. The water purification service had the lowest value, which only counted for 0.09%. The system service value went up about 7.90×105 yuan per hectare, which was smaller than that of Hechuan Wetland, another wetland located in Shaanxi Province.[Conclusion] The total value of the ecosystem service functions were about 3.30×108 yuan. The indirect use value of ecosystem service accounted for 90.5%, which was markedly higher than that of the direct use value (9.5%).
