Abstract: Spatial equilibrium allocation for multiple water resources in basin is an important practical issue,and it is also a difficulty in realizing scientific water diversion. A variety of water sources such as surface water,groundwater,and water diversion,unconventional water resources and various water users like domestic water,industry water,agriculture water,ecology water are involved in water resources allocation of the Huangshui River Valley. A spatial equilibrium allocation model for multiple water resources in the Huangshui River Valley including three sub-models for the optimization of total water diversion,each project water diversion and multiple water resources allocation,respectively,based on the hierarchical optimization theory is proposed. The corresponding method and strategy are employed to solve the proposed models. The optimized water diversion scales and water resources allocation plans considering with economic feasibility are obtained under the constraint of strengthening watersaving. The proposed technology and method represents the principles of the water-saving priority,ecological priority and spatial equilibrium in China,which can be used for basin water resources allocation and water diversion project demonstration.
