摘要
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 area of Bobal Bay of the North-China plain had involved four-times marine transgression since Upper Pleistocene epoth. The textrues of the epidermis structure and the paleoclimate feasures differ in different stages of marine transgression. On base of reconstruction of geologic development history and that of paleorgeography & paleoclimate, Authors discuss the locus of evolution of the hydrous medium, and divide the process of evolitionary trend in four paleostructure-hydrogeologic stages (cycles). We select Tang-Chin littoral area as model area for environmental forecasting. The research provides scientific & manage basis for utilizing and exploiting resources of ground water.
