Abstract

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 x hm(-2), per unit water conservation volume supplied by grassland ecosystem was 1110.7 m3 x hm(-2), and ecological compensation criterion was 788.6 yuan x hm(-2). The total water conservation volume supplied by grassland ecosystem was 2.56 x 10(9) m3.

摘要

定量设定生态补偿标准是建立生态补偿机制的重点和难点。基于甘南藏族自治州1987 - 2007年气象数据和2007年社会调查数据，采用最小数据法、社会调查法和降水贮存量估算方法模拟了该地区草地生态系统服务供给曲线。2007年该地区实施生态补偿的机会成本为503.6元·hm-2，草地生态系统单位供水量的机会成本为1110.7 m3·hm-2，生态补偿标准为788.6元·hm-2。草地生态系统的总供水量为2.56×109 m3。
