摘　　要：生态补偿标准的确定是生态补偿机制建立的难点和重点.根据1987—2007年甘南州气象站和2007年甘南藏族自治州的社会调查资料,采用最小数据方法、社会调查法、降水储水量法对草地生态系统服务的供给曲线进行模拟.结果表明:2007年,甘南藏族自治州年实施生态补偿的机会成本为503.6 yuan.hm-2,草地生态系统提供的单位水源涵养量为1110.7m3.hm-2,补偿标准为788.6 yuan.hm-2,草地生态系统提供的总水源涵养量为2.56×109m3.Quantitatively setting ecological compensation criterion is a focus and a difficulty in establishing ecological compensation mechanism. Based on the 1987-2007 meteorological data and the 2007 social survey data of Gannan Tibetan Autonomous Region, the supply curves of grassland ecosystem services in the Region were simulated by the methods of minimum-data, social survey, and precipitation storage estimation. The opportunity cost of implementing ecological compensation in the Region in 2007 was 503.6 yuan · hm-2, per unit water conservation volume supplied by grassland ecosystem was 1110.7 m3 hm-2, and 788.6 yuan· hm-2. The total water conservation volume ecological compensation criterion was supplied by grassland ecosystem was 2. 56×10^9m3.
