地下水的合理开发利用在南水北调中的作用

在系统阐述地下水资源概念和地下水含水层特点的基础上，分析了南水北调受水区地下水开采现状，探讨了解决城市和农村地下水超采的措施，利用地下水超采形成的地下库容调蓄当地降雨径流和引江水、合理开发利用地下水提高水资源利用率和利用改造咸水、防止土壤盐碱化等在南水北调中的作用。

The Functions of Rational Exploitation and Utilization of Groundwater Resources in South-to-North Water Transfer Project

In this paper, on the basis of the systematically clarified concepts of groundwater resources and the characteristics of groundwater aquifers, the present situation of groundwater exploitation in the water receiving areas of the South to North Water Transfer Project is analyzed, the measures for the control of groundwater overdraft in urban and rural areas and the effects of storage and regulation of local rainfall runoff and water diverted from Changjiang River, rational development of groundwater and utilization and desalinization of saline groundwater for the promotion of the water use efficiency and salinity control in the South to North Water Transfer Project are investigated.
