华北平原渤海湾海岸带从晚更新世以来经历了四次海侵。备个海侵期的沉积层结构特点及古气候特征均有差异。作者在再造地质发展史、古地理及古气候环境的基础上，讨论了本区含水介质演化的轨迹，并将演化趋势过程划分为四个古构造—水文地质期（旋回）。作者选择唐秦滨海地区为模式区对地下水动态进行了预测，旨在为利用和开发本区地下水资源提出科学管理依据。
The coastal zone of the Bohai Gulf in the North China Plain has undergone four transgressions since the late Pleistocene. There are differences in sedimentary structure and palaeoclimate characteristics during the transgression. On the basis of reconstructing the history of geology, palaeogeography and paleoclimatic environment, the author discusses the trajectory of the evolution of water-bearing media in this area and divides the process of evolution into four palaeo-hydrogeological periods (cycles). The author chooses Tangqin Binhai area as a model area to predict the groundwater dynamics, aiming at putting forward scientific management basis for utilizing and developing the groundwater resources in this area.
