【摘要】 为了探明辽东湾区海底地形,通过测深系统对辽东湾区海底地形进行了高进度、全覆盖测量,进而根据地形起伏特点对辽东湾区海底地形进行了分区,并分析了影响辽东湾地形发育的主要因素。结果表明:辽东湾区海底地形分为5个子区,地形发育受地质构造、水动力来源和沉积物供应的复合影响。更多还原

【Abstract】 The Liaodong Bay of the Bohai,rich in oil,has been investigated by a large number of geologists,but most of research was focus on structural geology.Through the survey by single beam echo-sounder system,the submarine topography of the Liaodong Bay was studied.Topographical features of the seabed topography in the Liaodong Bay were divided into five sub-zones,and factors affecting the development of terrain in the Liaodong Bay were also discussed.The formation of topography in the Liaodong Bay is affected by structural geology condi-tion,hydrodynamic condition,and sediment supply.更多还原
