基于污染损失责任分摊的流域水污染补偿额度测算--以湘江流域长株潭段为例

Estimation of water pollution compensation in watershed based on responsibility-sharing of pollution loss

生态补偿是生态文明建设的重要手段,补偿额度作为生态补偿的关键受到广泛关注。文中通过构建责任分摊比模型和补偿总额测算模型来计算上下游之间补偿额度。结果表明:2015年湘江流域长株潭段,湘潭地区污染上游占67.8%,株洲补偿给湘潭97.83万元。长沙地区污染本地占79.7%,湘潭地区补偿给长沙地区917.6万元。

Ecological compensation is a significant mean to build the ecological civilization,the amount of compensation as the key of ecological compensation has attracted great attention. Taking Chang-Zhu-Tan Section of Xiangjiang river basin as an example,we calculated the compensation amount between the upstream and downstream by constructing the model of the liability apportionment ratio and the total compensation calculation model. The results show that 67. 8% of the pollution in Xiangtan came from upper reaches,so 978,300 Yuan of compensation to Xiangtan should be from Zhuzhou. Local pollution in Changsha accounted for 79. 7%,Xiangtan area should pay 9. 1176 million Yuan of compensation to Changsha.
