| 摘 要： | 依据野外实地考察及有关资料,分析了大沽夹河滨海平原的构造基础、沉积层序及其时代,对本区全新世以来的海岸变迁进行了探讨。认为距今5500～6000年海侵达到最大范围,形成超出现代平均海平面3m左右的高海面;高海面之后的海退过程中有两次停顿,形成两道滨岸沙堤。

| Abstract: | According to field trip and related informations, having analysed geological structures, sedimentary facies and its era for the strand plain of the Dagujia River, the authors research to the coastline changes of the area in Holocene and consider that about 5500-6000 years BP, the transgressive extent was the largest. The high sea-level about 3m above mordern sea-level was formated at the same time. After the period of high sea-level, there were two periods of stabilization in the regression and two beach ridges were formated. |
