京津冀合作水源保护林生态效益补偿分摊研究

Study on the Allocation of Compensation for Ecological Benefit of Water Source Protection Forest of Beijing Tianjin and Hebei Cooperation

以京津冀合作水源保护林生态效益补偿分摊问题为研究对象,介绍了京津冀合作水源保护林生态效益补偿的背景和存在的问题,分析了水源保护林生态效益补偿分摊的必要性,构建了京津冀合作水源保护林生态效益补偿分摊核算指标体系,并对京津冀合作背景下的京冀合作水源保护林项目一期工程中的潮白河水系进行实证研究,结果表明:京冀合作水源保护林的生态效益具有外溢效益,即受水区存在正外部性,应由受水区和水源区共同分摊。可以计算出受水区向水源区进行生态效益补偿时其补偿标准的上限。受水区和水源区对京冀合作水源保护林项目的生态补偿分摊系数应是动态变化的。

The paper studies on the allocation of compensation for ecological benefit of water source protection forest of Beijing Tianjin and Hebei cooperation,introduces the background and problems of compensation for ecological benefit of water source protection forest of Beijing Tianjin and Hebei cooperation,analyses the necessity of ecological benefit compensation allocation,sets up an accounting index system of ecological benefit compensation allocation in Beijing Tianjin Hebei cooperation of water source protection forest,and makes an empirical research which takes Chao Bai river water system as an example.The conclusion is that the ecological benefit of water source protection forest of Beijing and Hebei cooperation exists the spillover effect evidently which means that compensation for ecological benefit should be allocated by both Water-Receiving Area and Water Source Area,because the ecological benefit of water source protection forest exists the positive externality.The paper calculates the maximum of compensation for ecological benefit which the Water-Receiving Area should undertakes,and also concludes that the allocation coefficient should changes dynamically in the compensation for ecological benefit of water source protection forest.
