Abstract: In this paper,the ecological compensation of a desert water-lifting irrigation project was discussed,the ecological service values of vegetation increased by emigration from the Qilian Mountains to the Jingdian Irrigated Area were calculated by factor equivalence,the ecological service values by reducing sandstorm in the leeward area were estimated using cosine distance formula,and the opportunity cost was also calculated.The results showed that: ① Ecological compensation should be based on the opportunity cost of the external ecosystem service value.The ecological service value of the Jingdian Irrigated Area from the Qilian Mountains ecological migration to vegetation regeneration of the Qilian Mountains is 4.01×109 yuan RMB,and the ecosystem service value by reducing sandstorm in the leeward area is 7.09×107 yuan.Opportunity cost of the ecological migration is 2.05×108 yuan,and the opportunity cost of controlling sandstorm in the leeward area is 3.63×106 yuan; ② The main beneficiaries of vegetation regeneration by ecological migration from the Qilian Mountains to the irrigated areas are the counties in the Shiyang River Basin and Jingtai County in the eastern Qilian Mountains in the Yellow River Basin.The state is also one of the beneficiaries.Subjects of the compensation are Gansu Province and Administration of Jingtaichuan Water-lifting Irrigation Project; ③ The prevention and control of desertification and sandstorm and the protection of national ecological forest are the emphases of ecological environment construction in China.Ecological compensation is conducive to driving and promoting the development of similar public welfare undertakings,and vigorously promoting the national ecological environment construction.
