The invention relates to a method for determining filling area of spraying and dropping irrigation. The method is that an irrigation area is divided into a plurality of irrigation units; the area of the irrigation units is determined; the filling area and the number of filling areas are determined according to the formula of irrigation unit area=filling area* filling area number, wherein the irrigation unit area is the irrigation area controlled by a pump station or a set of mobile water pump units; the relationship between the filling area and the construction cost of spraying and dropping irrigation is that the construction cost lowers when the filling area is small; the construction cost is high when the filling area is large; the cost is in direct proportion to the filling area in the construction cost of spraying and dropping irrigation; the relationship between the filling area and the irrigation cycle is that the irrigation cycle is increased when the filling area is small, and the irrigation cycle is decreased when the filling area is large; the filling area can be determined according to the construction cost of spraying and dropping irrigation and the irrigation cycle. With the adoption of the method, the problem of insufficient optimization and high cost of the existing spraying and dropping irrigation engineering can be effectively solved.
