华北地区深层地下水修复思路与对策

The ideas and strategies for the restoration of deep groundwater in North China

华北地区长期超采深层地下水,引发地面沉降等一系列严重生态与地质环境问题,给华北地区尤其是京津冀水安全和可持续发展带来重大威胁,开展深层地下水治理修复意义重大。剖析华北地区深层地下水超采现状及问题,梳理国内外深层地下水人工回补实践经验,按照“点、线、面”结合的工作思路和“压采、补给、回补”的系统治理修复模式,提出试点修复措施与对策,为下一步深层地下水超采治理修复提供参考。

The continuous deficit of deep groundwater caused by long-term exploitation in North China has caused a series of serious ecological and geological environmental problems such as land subsidence,which poses a great threat to the water security and sustainable development in North China,especially in Beijing,Tianjin and Hebei.It is of great significance to carry out deep confined groundwater treatment and restoration.Analyzes the present situation and problems of overexploitation in North China,then combs the practical cases of artificial recharge for deep groundwater at home and abroad.Finally,according to the working idea of the combination of“point,line and surface”and the systematic treatment and repair mode of“pressure mining,surface recharge and artificial recharge”,the measures and countermeasures are put forward to provide reference for the next step of deep confined groundwater treatment and restoration.
