Abstract: In view of the contradiction between agricultural water demand and the ecological base flow in the northwest arid and semi-arid area, this paper proposed a method of calculating the agricultural ecological compensation standard based on the river's ecological base flow. The crop water requirement coefficient was introduced to establish the relationship between the agricultural water shortage and the yield loss due to the protection of ecological base flow and to calculate the amount of agricultural ecological compensation. Taking Baoji Gorge Irrigation Area as an example, the agricultural ecological compensation quantity based on the ecological base flow was calculated. The upper limit was 525 million yuan and the lower limit was 37 million yuan according to the different situations in Baoji Gorge Irrigation Area. Farmers in Baoji Gorge Irrigation Area who lose the yield because of the ecological basic flow are the objects of ecological compensation, and the administrative departments of the river basin are the subjects of the compensation. In order to improve the sustainable development of agriculture in Baoji Gorge Irrigation Area, the implementation of ecological compensation should not be limited to the payment in cash and can be the investment in construction, etc.

Key words: agricultural ecological compensation, agricultural water demand, Baoji Gorge Irrigation Area, river ecological base flow
