Abstract: The desertification of land leads to a decrease in the amount of usable land and brings about serious economic and social problems, making it one of the most catastrophic environmental problems confronting human society today. In order to curb desertification effectively, in 2013, the State Forestry Bureau started to implement the subsidy system for the protection and closure of desertified lands in areas where land desertification was serious. During the construction of desertification protection reserves, the ecological compensations is vital, which encourages farmers to voluntarily exchange their semi-desertified or desertified farmlands with lands that produce low yields and need huge irrigation requirements. Based on the practice of enclosed protection area of desertified land in Minqin County of Gansu Province, the paper estimated the ecological compensation standard that can encourage the farmers to voluntarily transform desertified farmland into protected zone with Minimal Data Method. The paper used water resource service to represent the ecosystem services output after the change of land management and deduced the water resources service supply curve based on the opportunity cost of the farmers obtained from survey. The quantitative relationships between the compensation standard, land conversion ratio and water resource supply were calculated. The results show that: 1) The implementation of the compensation can encourage farmers to change the way cultivating land use, reduce irrigation water and increase ecological water supply in Minqin County and Shiyang River Basin. 2) According to the plan of Minqin County, the total area of the forbidden reserve will be 15 500 hm2 and the expected water resources output will be 102 million m3, which could be achieved by a compensation standard of 19 770 yuan/hm2. 3) Based on a compensation standard (3 600 yuan/hm2) for new-round Grain for Green Project, only 3.51% of the desertified land could be transformed into protected zone. Therefore, the compensation standard should be improved.
