生态建设补偿的定量标准——以南水北调东线水源地保护区一期生态建设工程为例

生态补偿标准的确定是生态补偿机制建立的重点和难点.以南水北调东线水源地保护一期生态建设工程的补偿为例,探讨生态建设的补偿标准.从工程投资和机会成本的角度分析生态建设的总成本为1.46亿元/年,通过生态系统服务价值评价并结合专家咨询赋权,计算出生态建设工程成功实施后,建设区域所增加的生态服务效益为0.83亿元/年,外部区域所增加的生态服务效益为2.13亿元/年;综合生态建设成本和生态效益,提出了根据生态服务效益分担生态建设成本的补偿标准分析思路,并由此计算得到外部区域对建设区域的补偿标准为1.11亿元/年.

The ecological compensation standardization for ecological restoration: a case study of ecological restoration in the water resource protection zone for Eastern South-to-North Water Transfer Project

Quantitatively setting ecological compensation standardization was a focus and also a difficulty for the establishment of ecological compensation mechanism. As a case study, the economic compensation calculation of the first stage ecological construction project in the water resource protection zone for Eastern South-to-North Water Transfer Project was discussed basis on restoration cost and ecosystem service value assessment. The ecological restoration cost of the first stage for the water resource protection zone was calculated as 146 million yuan per year, and the ecological befits calculated for the restoration area and the exterior area were 83 million yuan and 213 million yuan per year respectively based on valuation of ecosystem service added. According to the basic principle of ecological compensation, the exterior ecological benefited region should compensate the cost of the restoration project, it was proposed the compensation proportion of the exterior area to the construction cost can be calculated based on the ecological benefit proportion it gained from the restoration project, and the compensation amount of the exterior area was calculated as 111 million yuan per year.
