• Agricultural planting structure
• Agricultural water resources
• Optimal allocation

A model for agricultural water resources optimal allocation is established by taking the maximization of the net irrigation benefit as a target in this paper. The first level is partition subsystem, and at this level an optimal allocation model of water supply for different crops is established. The second level is the irrigation area overall system, and at this level an optimal allocation model of water supply for different partitions is established. This model is applied in Tao Cheng-Pu Yellow River Irrigation Area in Shandong Province to optimize the agricultural planting structure and the annual distribution of surface water and ground water in different periods. The results show that compared with present, the optimized net irrigation benefit increased about 23.7% and the optimization scheme is feasible, which provides a scientific basis for the adjustment of agricultural planting structure and the management of water in this area.
