摘要
制定科学合理的跨流域调水工程水价是开展水源区生态补偿的重要途径之一.在现有水价的基础上,新增生态补偿作为水价的重要组成部分,运用机会成本法测算南水北调东线工程水源区生态补偿标准,并引入社会发展阶段系数和政府支付能力系数对其进行修正,构建计入生态补偿的南水北调后续工程水价定价模型.以南水北调东线一期工程胶东干线为例,得到 2016、2020 年水源区的理论生态补偿标准分别为 116.121、199.992 亿元,在现行价格基础上水价需分别提高 0.93、4.51 元/m3.结果表明,生态补偿会耗费大量资金,只有当工程调水能力达到规划设计规模时,持续性调水才能逐步降低供水成本,否则水价会超出受水区的承受范围,工程效益也难以发挥.
Abstract
Establishing scientific and reasonable water price for inter-basin water transfer projects is one of the impor-tant ways to carry out ecological compensation in water source areas.On the basis of the existing water price,this paper adds ecological compensation as an indispensable part of the water price,measures the ecological compensation standard for the water source area of the East Route of the South-to-North Water Diversion Project by using opportunity cost method.The social development stage coefficient and the government payment capacity coefficient are introduced to modi-fy it,so as to construct a water resource pricing model for the subsequent projects of the South-to-North Water Diversion Project that includes ecological compensation.Taking the Jiaodong Main Line of the Phase I of East Route of the South-to-North Water Diversion Project as an example,the theoretical ecological compensation standards for the water source area in 2016 and 2020 were 11.612 1 billion yuan and 19.999 2 billion yuan,respectively.Based on the existing water prices,the water price per cubic meter needs to be increased by 0.93 yuan and 4.51 yuan,respectively.The results indi-cate that ecological compensation will consume a large amount of funds.Only when the water transfer capacity of the pro-ject reaches the planned design scale,continuous water transfer can gradually reduce the water supply cost.Otherwise,the wa-ter price will exceed the bearing range of the receiving area,and the benefits of the project will be difficult to achieve.
