【 摘 要 】

The Hebei water-recipient area of the middle route project of China's South-to-North Water Diversion Project (SNWD Project) is located in the Haihe River Basin, which was arid and had higher utilization intensity than other regions in China. Surface water shortage and groundwater over-pumping caused the world's largest underground water funnel group in the research area. Water supply from the middle route of the SNWD Project is of great significance to ease acute water shortage, alleviate groundwater over-pumping and improve groundwater quality in Hebei water-recipient area. The purpose of this article was to evaluate the eco-economic benefits of the delivered water from the middle route of SNWD Project to alleviate groundwater over-pumping in Hebei water-recipient area by means of reference model method, cost-benefit method and substitute cost method. The results of reference model method, cost-benefit method, and substitute cost method were 5.526, 10.770 and 9.831 billion Yuan per year. While, the cost of delivered water in Hebei water-recipient area was 6.592 billion Yuan per year. From this point of view, the middle route of SNWD Project is very profitable in alleviating groundwater over-pumping in Hebei Province.
