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。

The characteristics and formation of the submarine topography in the Liaodong Bay, the Bohai Sea
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 condition, hydrodynamic condition, and sediment supply.
Key words:  topography  the Liaodong Bay  zoning
