南水北调中线工程生态补偿计算研究

跨流域调水生态补偿的计算方法和考虑因素直接影响着受水区在调水工作中的参与热情.本研究以南水北调陕西汉中、安康、商洛水源区及京、津、冀、豫受水区为研究区,在考虑水源区水土保持建设、受水区水市场情况、水源区水资源价值、水源区排污权损失价值基础上,加入未来水资源调度机会成本、市民意愿支付差价占比及意愿支付补偿额占比,重新计算生态补偿总量.得陕西水源区当前可计算的受水区补偿额为62.42亿元/年.为发展中南水北调中线工程生态补偿计算提供新的计算思路和方法.

A Study of Eco-compensation Calculation for the Middle Route Project of South-to-North Water Diversion

The total amount of ecological compensation for any inter-basin water diversion project is directly related to the enthusiasm of the water intake areas. In order to provide new calculation ideas and methods for the computation of ecological compensation for the middle route project of South-to-North Water Diversion, a study was made to re-compute the total amount of ecological compensation of the project based on Hanzhong, Ankang and Shangluo in Shaanxi as the water source areas and Beijing, Tianjin, Hebei and Henan as the water receiving areas and considering both the water market situation in the water receiving areas, the water and soil conservation measures, the water resource value and the cost of waste water discharge in the water source areas, on the one hand, and the future opportunity cost of water resource allocation in the water source and public willingness to pay the difference proportion and to pay the compensation ratio, on the other. The results showed that Shaanxi should get a compensation of 6.24 billion RMB per year from the water receiving areas.
