弄清补偿标准和新增生态系统服务供给量之间的关系是生态补偿研究中的关键问题。舟曲县现有的补偿是静态补偿，补偿标准低。没有很好地达到改善生态环境的目的。本文基于最小数据方法。以耕地和林地提供的水土保持量的差异表征生态系统服务，通过提供单位水土保持服务的机会成本的空间分布，推导出舟曲县森林水土保持的供给曲线，从而将补偿标准和新增水土保持服务的供给联系起来。同时对比了3种补偿标准下的退耕比例、生态补偿总资金需求和新增水土保持量。研究表明生态补偿在理论上可以提供舟曲县的水土保持能力。随着补偿标准的提高，新增水土保持量也在增加。当补偿标准为250元／亩时，退耕比例仅为8．26％，生态补偿总资金需求为1930．03万元，新增水土保持量为469×10^4t；当补偿标准提高到518．63元／宙时。退耕比例增加到49．54％，总资金需求为23184．26万元，新增水土保持量为2．83×10^5t；当补偿标准增加到995．65元／亩时，退耕比例可达到98．79％，总资金需求为87340．95万元，可新增水土保持量达到5．65×10^5t。

Modeling the relation between payments criterion and the supply of additional ecosystem services is critical in ecological compensation. The existing payments in Zhouqu County are static and the payments criterion is relatively low. It is far from achieving the purpose of improving ecological environment. Based on the minimum-data approach, the ecosystem services are measured by the difference of conservation of water and soil between two kinds of land-use farmland and forest. The supply curve of forest service of conservation of water and soil in Zhouqu County can be derived from the spatial distribution of opportunity cost in providing those services. So the compensation criterion can be linked to the supply of additional conservation of water and soil. The proportion of conversion of farmland to forest, the total payments for ecological compensation and the additional conservation of water and soil are compared under three different compensation criteria. The results show that it is theoretically possible to enhance the eapabililij of conservation of water and soll by implementing ecological compensation in Zhouqu County. With the elevation of payments criterion, the additional conservation of water and soil also increases. When the payments criterion equals to 250 yuan/mu, 518.63 yuan/mu and 995.65 yuan/mu respectively, the proportion of conversion of farmland to forest rises from 8.26 percent to 49.54 percent and to 98.79 percent, the total payments for ecological compensation equal to 1 930.03 million yuan, 23 184.26 million yuan and 87 340.95 million yuan respectively, and the additional conservation of water and soil amount to 4.69 ×10^4 ton, 2.83 ×10^5 ton and 5.65 ×10^5ton respectively.
