流域水资源保护补偿博弈分析及蚁群算法解

协调好流域上下游间的收益问题，使上下游和谐发展，实现全流域收益最优，是目前我国流域水资源保护补偿研究和实践中的重点。论文从博弈论的角度研究流域水资源保护补偿中上下游间的行为和收益问题，建立了行政调节的流域水资源保护补偿博弈模型，利用蚁群算法实现模型最优求解。将该模型应用于晋江流域，结果表明：当上游的安溪县、德化县、永春县以及南安市（上游部分）提供给下游的水量分别为0.87×10⁸、0.75×10⁸、0.85×10⁸和0.76×10⁸ m³时，分别可获得0.925×10⁸、0.673×10⁸、0.949×10⁸和1.019×10⁸元的经济补偿，同时下游地区获得48.765×10⁸元的效益，此时流域总收益最大。上游地区合理供水可大幅提升全流域的收益，下游给上游合理补偿能够协调上下游关系，促进上下游的和谐发展。

Game Model for River Basin Water Resources Protection Compensation Solved by Ant Colony Algorithm

How to coordinate the interests between basin upstream and basin downstream and achieve harmonious development between basin upstream and basin downstream and maximize the interests of the entire river basin is the principal contradiction in river basin water resources compensation in China. In order to study the protection compensation mechanism of river basin water resources, this paper formulates scientific compensation standard of water protection and promotes reasonable protection and utilization of the river basin water resources. It studies the behavior and interests of the basin upstream and downstream from the perspective of the game theory, then puts forward a basin water resources protection compensation game model of administrative regulation, which is solved optimally by the Ant Colony Algorithm. The model is applied to the Jinjiang River Basin, the results show that when the upstream of Anxi, Dehua, Yongchun and Nan'an (the upper part) provides water to the downstream is 0.87×10⁸m³, 0.75×10⁸m³, 0.85×10⁸m³ and 0.76×10⁸ m³, respectively, it can obtain 0.925×10⁸ yuan, 0.673×10⁸ yuan, 0.949×10⁸ yuan and 1.019× 10⁸ yuan economic compensation, at the same time, the downstream area receives 48.765× 10⁸ yuan benefits, the total benefit in the basin reaches the maximum. A reasonable water supply from the upstream region can significantly improve the interests of the whole basin, the downstream provides reasonable compensation funds for the upstream can make the relationship between upstream and downstream coordinated, narrow the economic and social development gap between the upstream and downstream and promote the harmonious development between the upstream and the downstream. Meanwhile, using Ant Colony Algorithm to solve the model is easy to form computer languages, which brings high computing speed, high efficiency, good convergence performance and the easy way to find the global optimal solution. Through the establishment of administrative regulation game model, the scientific computing of the amount of water transferred and the compensation standard, this paper realizes the benign interaction of water protection among the upstream and downstream, water supply area and intake area. It is of great importance and value to the establishment of protection mechanism of river basin water resources and the promotion of the unified management of river basin water resources.
