    渤海辽东湾海域海底底形特征及控制因素

    FEATURES AND ORIGIN OF SUBMARINE BEDFORMS IN THE LIAODONG BAY, THE BOHAI SEA

    • 摘要: 基于我国海洋区域地质调查项目获取的水深、侧扫声呐、单道地震和浅地层剖面数据,结合前人的研究成果,对渤海辽东湾海区的海底底形的类型及分布特征进行了系统分析。研究发现,辽东湾海底底形类型丰富,有潮流沙脊、潮流沙席、潮流冲刷槽、古河谷、古湖泊洼地等多种类型。海底底形的发育形态是构造和古地貌、沉积物供给、海平面变化及环境变迁、水动力塑造等多种因素综合作用的结果。

       

      Abstract: The types and distribution characteristics of submarine bedforms in the Liaodong Bay of Bohai Sea are described in this paper based on historical data, results of previous studies and the data obtained in the bathymetric, side san sonar,single-channel seismic and subbottom profile surveys carried out during the marine fundamental geological survey programs in China. There are various submarine bedforms,such as the tidal ridge,the tidal sand sheet,the tidal scour trough,the buried river vallies and the buried lakes.The factors that influence and control the seafloor bedforms development in the Liaodong Bay are discussed from the aspects of geological structure, sea-level and environment change, and river and tidal hydrodynamics.
