河北省深层地下水回补研究OA

In recent years,Hebei Province has taken comprehensive approaches to control groundwater overexploitation in order to deal with serious problems of water shortage and depression funnels that has existed for a long time and alleviate ecological and environmental degradation.Recharge of deep aquifer acts as an important measure to slow down ground subsidence,control depression funnel,and seawater intrusion.Typical cases and methods of groundwater recharge are introduced,with analysis on main challenges faced by artificial recharge of deep aquifers from three aspects of mechanism,technology,and economy,and focuses on the progress of pilot projects and layout of experimental sites for recharge of deep aquifers in Hebei Province.Based on the actual situation in Hebei,suggestions are made for the recharge of deep aquifers,aiming to provide useful experiences for systematic restoration of deep aquifer,increase capacity of strategic reserve,and sustainable utilization of groundwater resources.
