摘要
基于我国近海地形地貌调查项目获取的水深、侧扫声纳及浅层剖面数据,结合渤海海域历史资料和前人相关工作、研究成果,对渤海地貌类型和分布特征进行了描述。在一些重点区域通过最新调查资料和历史资料的对比,描述了地貌的变化趋势,在此基础上编绘了渤海海底地貌类型图,并从地质构造、海平面变化、河流和海流等水动力作用以及人类活动几个方面对影响渤海海底地貌发育的因素进行了讨论。
The geomorphological types and their distribution characteristics in the Bohai Sea are described based on historical data, results of previous studies and the data obtained in the bathymetric, side scan sonar and subbottom profile surveys carried out during the coastal topography and geomorphology programs in China. The geomorphological evolution tendency in some key areas is discussed by comparing the historical data to the newly-obtained investigation results. Meanwhile, the factors that influence and control the seafloor geomorphological development in the Bohai Sea are analyzed from the aspects of geological structure, sea-level change, river and tidal hydrodynamics and human activities.
