摘要
Based on the analysis of the evolvement of deep confined groundwater depression cone and the assessment results of groundwater resources,considerable amount of recharge was found to be acquired by deep confined water after long time of high-intensity exploitation.But,more than half of the recharged water are not sustainable,deep confined water production must be depressed to cope with the geological problems such as ground subsidence.Shallow brackish water exploitaion can provide about 0.2 billion m3/ a water resources,and can also enhance the infiltration of precipitation,and improve the quality of shallow groundwater.This is an important approach to resolve the water shortage problem of Cangzhou area.
