Study on Balanced Allocation of Water Resources in the Yellow River Basin Based on Water Benefit Sharing

In recent years, the shortage of water resources and the deterioration of water ecological environment have led to the increasing contradiction between supply and demand of water resources in river basins. How to realize the balanced allocation and scientific regulation of water resources in river basins is a serious challenge for China to face water resources problems. In this paper, the dynamic process and allocation scheme of water resources and water benefit allocation under different cooperative scenarios are simulated by constructing the water resources equilibrium allocation model of water benefit sharing. The influencing factors of water benefit sharing mechanism and the process of allocation compensation are studied, and the benefit relationship in regional coordinated utilization of water resources is revealed. The upstream, midstream and downstream water users of the Yellow River Basin are formed into alliances, respectively. Based on the principle of master-slave game theory, a basin system optimization problem with multi-level hierarchical structure is established. The initial allocation of water resources is carried out with the maximum overall benefit of water resources allocation, and the incremental benefits of the system optimization compared with the current individual and overall benefits are analyzed. The fuzzy cooperative alliance is used to allocate incremental benefits, improve the stability of cooperation among alliances, realize the cooperation and interaction of water resources in distribution, and finally achieve a dynamic equilibrium state. This paper focuses on the allocation mechanism of water resources competition and cooperation under water benefit sharing, which can provide a scientific basis for improving water resources security in water shortage basins and adapt to new problems and challenges brought by changing environments.
