Based on the long sequence test results of mutual transformation between precipitation and crop water consumption and soil water from irrigation experimental station, water simulation module of the whole process of field scale Storage-Water Consumption-Irrigation-Drainages was built. Combined with the system simulation method, the simulation rules of water allocation for different types of ponds and backbone reservoirs are formulated. Then the water distribution simulation model of reservoirs and ponds combined irrigation system is established, to simulate irrigation water of diversion and pumping station, precipitation, soil water and their mutual transformation of Daguantang Reservoir irrigated area. To maximize economic efficiency as the goal under precondition of basic water irrigation water supply security. By using the principle of orthogonal test, water resources optimal regulation model of reservoirs and ponds combined irrigation system is constructed. Based on the simulation and orthogonal experiment, the water resources optimization control technology system is formed. The reasonable engineering layout size and scale of the Daguantang Reservoirs irrigation district are determined. The suitable water saving irrigation technology model and irrigation system are determined. Scientific scheduling rules of bonds and reservoirs are developed. Operable rules of crop planting structure adjustment are proposed. Storing runoff utilization of irrigation district is improved. To enhance the annual water supply capacity of bonds and reservoirs and the ability of drought resistance and disaster reduction. To provide theoretical basis for comprehensive treatment of Lake Chaohu Basin and the establishment of water allocation scheme of reservoirs and ponds combined irrigation district, scheduling rules of bonds and reservoirs and crop irrigation system.
