人工回灌地下水的有效途径和方法探讨

Study on Effective Way and Technology of Artificial Recharge of Groundwater

目前，华北地区水资源短缺，地下水超采日益严重。因此，开展地下水回灌的研究和应用也日益重要。文章在对大量人工回灌地下水的工程实例和方法进行调查分析的基础上，提出了对北方干旱半干旱地区进行大面积人工回灌地下水的有效途径和方法。并通过河北省雄县利用沟渠入渗回灌地下水的实例，给出在人工回灌条件下地下水的平衡计算公式及实测验证资料，对回灌的一些技术问题作了分析，同时，指出了通过沟渠入渗回灌地下水的必要条件和应采取的措施。

The water resources is short and groundwater is over exploited currently in Northern China. Therefore, it is very important to study and apply the technology of groundwater recharge. The effective way and technology of artificial recharge of groundwater in Northern arid and semi-arid region are presented in this paper based on investigation of artificial recharge examples and methods. The groundwater balance calculation formular and measured data under artificial recharge condition are given by using of a case study in Xiong county of Hebei province. The technical problems of recharge are analysed in this paper. Meanwhile, the necessity and adopting measures of groundwater recharge through canals and drains permeating are also presented.
