摘　　要：由于地下水的超采,已在沧县地区引发一系列环境地质问题。通过确定地下水控制性管理水位,来控制地下水的开采量,实现沧县地区浅层地下水资源的可持续利用。根据沧县地区浅层水位观测井的观测资料,分析了沧县地区浅层地下水位动态特征,发现地下水位呈周期性变化。在充分了解沧县地区水文地质条件的基础上,利用GMS软件建立沧县地区地下水水流模型。在现有的开采基础上,预测不同频率降水量情景下沧县地区浅层地下水控制性管理水位,并确定其阈值。四种情景下沧县地区浅层地下水控制性管理水位阈值分别为:-6.40~7.00m、-4.30~7.30m、-4.70~7.10m、-4.50~7.00m。最终确定沧县地区浅层地下水控制性管理水位阈值为-6.40~7.30m。Due to the over-exploitation of groundwater, a series of environmental and geological problems have been triggered in Cangxian area. This paper was intended to determine the controlled management level of groundwater as a way to control the exploitation quantity of groundwater and to realize sustainable utilization of the shallow groundwater resources in Cangxian area. Based on the observation data from the shallow water level observation wells in Cangxian area, we analyzed the dynamic characteristics of shallow groundwater level in Cangxian area, and found a periodical change of the groundwater level. Based on a substantial understanding of the hydrogeological conditions in Cangxian area, we developed a groundwater flow model of Cangxian area with the GMS software On the basis of the current exploitation situation, we predicted the controlled management level of shallow groundwater in Cangxian area under 4 different precipitation frequency scenarios, and determined the threshold value. The threshold values under the 4 scenarios were - 6. 40～7. 00 m,-4. 30～7. 30 m,-4. 70～7. 10 m,-4. 50-7. 00 m respectively. The controlled management water level threshold of the shallow groundwater in Cangxian area was finalized to be --6.40～7.30 m.
