面源污染防治视角下农村土地经营方式选择的博弈分析

随着点源污染逐步得到有效控制和治理,农村面源污染上升为影响环境尤其是水环境的重要污染源。分析农业面源污染现状及成因,建立村集体与农户间土地生产方式博弈模型,博弈分析表明:农村面源污染受多方面因素影响,地方政府的监管对农民的经营方式选择有着重要影响;政府除了要加大对污染物末端的技术治理外,更应该重视源头控制,即由地方政府运用适当的治理政策对农户行为进行调节,从而将农户高消耗、高投入的传统经营方式转为更加注重环保的生态型经营方式。

Game analysis for choice of management modes of rural land in the perspective of non-point pollution prevention

With the gradually effective control and governance of point source pollution, the non-point source pollution in the rural area turns into the major pollution source which affects the environment, especially the water environment. The current status and causes of the non-point source pollution in the rural area are investigated. A game model for the production ways of the collective''s and the farmers''lands is established. The game analysis shows that the rural non-point source pollution is influenced by various factors, and the regulation of the local government has an important influence on the choice of farmers''management mode. Besides the efforts of technical treatment of eternal pollutants, the government should pay more attention to controlling the source pollution, that is, the local government should adopt the appropriate governance policies to adjust farmers''behaviors, and make the traditional management mode of high consumption and investment be switched to the ecological one with environmental protection.
