基于博弈论的水资源保护补偿机制研究

Game theory based protection and compensation mechanism for water resources

【目的】建立基于博弈论的水资源保护补偿机制,为制定科学的补偿政策提供支持。【方法】运用博弈理论,建立基于政府参与协商调节的流域水资源保护补偿博弈模型,利用遗传算法对模型进行求解,并以泉州市晋江流域为例,对模型进行验证。【结果】该模型的建立及应用,晋江上游地区可获得5.418亿元的经济补偿,用于保护水资源;下游地区可解决2.8亿m3的缺水,创造52.674亿元的经济效益。【结论】所建立的流域水资源保护补偿博弈模型有效解决了流域上下游补偿中的利益冲突,调动了上游地区保护水资源的积极性,实现了整个流域利益的最大化,可为合理制定补偿政策提供一定的指导。

【Objective】 This study aimed to establish a reasonable mechanism of protection and compensation for water resources and make scientific policy based on game theory.【Method】 Game model of water resources protection and compensation in river basin was built based on participation of government in consultation and regulation.In this paper,we used the improved genetic algorithm to solve the model.At last the Jinjiang river in Quanzhou was selected to validate the model.【Result】 Based on the model,the upstream region of Jinjiang river could obtain economic compensation of 541.8 million yuan for the protection of water resources.At the same time,the downstream areas could reduce water shortages by 280 m3 and create economic benefits of about 5.2674 billion yuan.【Conclusion】 The results showed that the game model of water resources protection solved the conflict of interests on the upstream and downstream compensation effectively,mobilized the enthusiasm of the upstream basin to protect water resources,and maximized the interests of the entire river basin.
