水源保护区作为发展相对滞后的区域,经济发展与生态保护之间存在着明显的矛盾。从经济发展与环境保护之间的关系分析出发,运用外部性理论对水源区农业生产活动方式与经济效益、环境效益间的关系及区域内农民、区域外社会成员、政府之间的权利义务进行探讨,并通过水权理论提出了解决水源区生态保护外部性的途径。 As a relatively lagging region for water source protection, there are obvious contradictions between economic development and ecological protection. Based on the analysis of the relationship between economic development and environmental protection, the paper uses the theory of externality to analyze the relationship between agricultural production patterns, economic benefits and environmental benefits in the water source area and the rights and obligations between farmers, members of the community outside the region and the government Discusses and approaches the solution to the externality of ecological protection in water source area through the theory of water rights.
