Taking Shiping large irrigation area in Yunnan Province as an example, this paper studied the economic value of irrigation water and analyzed the influencing factors of crops in the irrigation area through the benefit sharing coefficient method and residual value method. It is found that the economic value of irrigation water for cash crops and fruits is higher than that for food crops. At the same time, it is recommended to use the benefit sharing coefficient method to calculate the benefits in irrigation district planning. The results of this study can guide similar irrigation district planning and help the construction of high standard modern irrigation districts.
