东海海底地貌主要由西部宽阔的大陆架浅水区和东部狭长的海槽深水区组成，根据地貌特征共划分为8个分区。本文结合地球物理勘探等调查成果，阐述了各分区的地貌、沉积物、水动力、矿产资源和潜在的海底地质灾害等基本特性。研究认为：冲绳海槽中的浊流沉积物，是东海大陆架边缘盆状洼地地貌形态演化的产物；东海海底地貌特征，既受控于地质构造，又受水动力和沉积作用的制约；大陆架地貌区主要受不同时期水动力和沉积作用的影响，而东部海槽区则主要由地质构造运动所支配。调查研究成果可为海洋工程规划建设与海洋资源开发利用及海洋地质深化研究提供服务。

The main seafloor landforms of the East China Sea are a wide continental shelf （shallow water） in the west and a narrow trough （deep water） to the east, and the sea is divided into eight sections based on geomorphological features. This paper uses the results of a geophysical exploration survey to define the basic characteristics of the landforms, sediments, hydrodynamic forces, mineral resources, and potential geohazards in each section. The results show that the turbidites of the Okinawa trough formed in the basin-like depression at the edge of the East China Sea continental shelf. Seafloor landforms in the East China Sea are controlled not only by the geological structure, but also by hydrodynamic forces and sedimentation. Continental shelf landforms are mainly controlled （at different periods） by hydrodynamic forces and sedimentation, while the eastern trough area is mainly controlled by tectonic movements. These results will be of use in marine engineering, construction planning, marine resource development and utilization, and for the ongoing development of research in marine geology.
