摘要
Over recent years, a number of geological survey data were obtained in coastal zone of Tianjin Binhai New Area. Respectively, using results of subbottom profiling to detect paleotopography, by sedimentary drilling borehole research to understand deposition times, use of land area chenier, buried oyster reefs, ancient tombs and burial sand distribution, study the distribution of the various periods of ancient shoreline position and morphology, and comparing with the depositional environment and topography in shallow sea area, a general introduction of topography and geomorphy evolution process after middle Holocene in Tianjin Binhai New Area was given in this paper.
