| 摘 要： | 本文对南黄海海底地势分区进行了研究,结果表明,南黄海是半封闭的内陆浅海,为新生代沉积盆地,深受外力作用的塑造。海底由西部缓倾斜地势区、西南部辐射状地势区、东部朝鲜半岛西岸水下冲刷槽沟地势区和中部浅海平原及黄海海槽地势区组成,形成由东西两侧向中部缓倾斜的基本面貌。

| Abstract: | In this paper, the sea bottom topography of the South Yellow Sea is classified into four types: (1) the western basin that slops down gradually from NW to SE, the platforms, the shallow canyons and the small geomorphic irregular regions. (2) the radiativetype relief of south-weatern basin that combines feature of the old Yellow River delta, the Yangtz River delta, the radiative-form sand dunes formed by the tidal currents, and the modern Yangtz River delta. (3) the erosional trough of the eastern basin off the west coast of Korea that is characterized by the existence of a series of parallel trenches and ridges. (4) the central shallow plain and Yellow Sea Trough area, the deepest area ia South Yellow Sea in north-south directions but turning to souther east and to connect the Jizhou Strait.The sea bottom relief were formed and influenced by both internal and external force. |
