农业面源污染控制中的博弈分析

当前农业面源污染已成为我国水体污染的主要根源和空气污染的重要来源，而化肥、农药等农资品污染是农业面源污染重中之重．运用博弈论的理论和方法构建农业面源污染控制中政府、农资经销商和农户博弈模型，分析其纯策略纳什均衡并求出混合策略纳什均衡解．研究表明，政府通过设置合适的对农资经销商补贴、对农户补贴以及农资经销商违规销售农资的罚金，可以提高农资经销商和农户参与控制农业面源污染的积极性和可能性，从而有效控制农业面源污染．

Fertilizers, pesticides and other agricultural products pollution in agricul- tural non - point source pollution is the priority among priorities.
