摘　　要：本文通过多年来大量的实际调查资料,将黄海划分成北黄海海湾潮流脊与岛礁、山东半岛沿岸水下堆积岸坡及水下阶地、南黄海西部弱堆积侵蚀平原、旧黄河-古长江三角洲堆积平原、海峡等七个地貌区,它们都各具特有的地貌类型。北黄海和南黄海原为两个大型的山间盆地,尔后由于海侵、被大量沉积物充填,成为今日连成一体的黄海浅海平原。Analyses of continuous sounding records, side scan sonar records, sub-bottom strata records and other data show that the Huanghai Sea can be divided into seven geomorphologic zones, namely: 1) the bay tidal sand ridges and island-reef geomorphologic zone in the northern Huanghai Sea,2) the submarine slope and the submarine terrace geomorphologic zone in the coastal zone of the Shandong Peninsula,3) the weak-accumulation erosional plain geomorphologic zone in the western part of the southern Huanghai Sea,4) the old Huanghe River-old Changjiang River delta accumulation plain geomorphologic zone,5) the eastern erosion-accumulation plain geomorphologic zone,6) the shallow accumulation plain geomorphologic zone in the center of the Huanghai Sea, and 7) the Strait geomorphologic zone. Tidal sand ridges, tidal channels and well-developed scouring trough around the Huanghai Sea are its prominent geomorphic features. The northern Huanghai Sea and the southern Huanghai Sea are actually two large paleo-intermonutainous basins. In the geologic past, as a result of several transgression-regression sequences, vast amount of terrigeneous material filled up the two basins into one, forming the present Huanghai continental shallow sea basin.
