东海陆架有两大现代泥质沉积区:一是沿着闽浙沿岸分布的沿岸泥质区(以下简称沿岸泥质区);二是东海陆架东北部的济州岛西南外陆架泥质区(以下简称外陆架泥质区).这两个泥质区的现代沉积物直接覆盖在沿岸砂质沉积和陆架残留沉积物之上.陆架其余地区大部分被所谓残留砂所覆盖.关于东海陆架泥质沉积,已有许多人进行过研究,但是多数只限于物质来源和分布特征,而很少探讨过物质沉积过程.然而,查明泥质沉积机制及其控制因素,对沉积学的研究有一定的理论意义,而且还可能有实用意义.因此,作者利用中美海洋沉积作用联合研究的海上调查资料,结合以往各家的研究成果,通过对比分析悬浮体、浮泥及表层沉积物三者的成分和分布特征同水文条件的关系,试图阐明东海陆架泥的沉积作用及其环境意义. There are two major modern muddy sedimentary areas on the East China Sea shelf: one is the coastal muddy area along the coast of Fujian and Zhejiang (hereinafter referred to as the coastal muddy area); the other is the muddy area of ​​the southwest outer shelf of Jeju Island in the northeast of the East China Sea shelf Referred to as the outer continental shelf muddy area.) The two modern sediments in the muddy area directly cover the sandy sediments and shelf sediments on the shelf. Most of the rest of the shelf is covered by so-called residual sand. Sedimentation, many people have been studied, but most are limited to the source and distribution of the material characteristics, and rarely discussed the process of material deposition.However, to ascertain the sedimentary mechanism of sediment and its controlling factors, the study of sediment has a certain Theoretical significance, but also may have practical significance.Therefore, the author makes use of the maritime survey data from the joint study of marine sedimentation between China and the United States, combined with the previous research results, through comparative analysis of the composition of the three components of suspended solids, mud and surface sediment And the distribution characteristics of the relationship with hydrological conditions, trying to clarify the East China Sea shelf sediment sediment and its environmental significance.
