摘　　要：分析深层地下水资源构成及40年来深层地下水水动力场、水化学场和开发利用状况,认为过量开采是深层地下水位持续下降和降落漏斗形成的主因,地下水降落漏斗的快速扩展是咸水入侵的根本原因。采用解析法计算两个约束条件下深层地下水的允许开采量2001.9 m3/a。提出了限量开采、回灌补源等防止咸水入侵的措施。From the analysis of hydrodynamic field, groundwater chemistry field, and the status of exploitation and utilization of deep confined freshwater for more than 40 years in Binzhou city,it is considered that over excavation of groundwater leads to widely descending of groundwater level and ~one of groundwater depression, and the rapidly expanding of groundwater depression leads to saltwater intrusion. In order to rationally utilize confined water and prevent saltwater intrusion, calculate the allowable yield about 2 001.9 m^3/a of deeply confined water is calculated under the constraint conditions of controlling groundwater lowering speed and preventing saltwater intrusion. This paper suggests adjusting exploitive positions ,reduing exploitation of deep confined water, moderately utilizing upper shallow groundwater, and deep groundwater recharge.
