本文论及的范围如图1所示。图1展示了从东海低潮线至约60m等深线之间的现代粉砂一淤泥沉积。该范围内约以30m等深线为界沉积了内侧以泥质粉砂、外侧以粉砂质泥为主的两种不同类型、呈条带状与岸线平行分布的现代沉积物。本文在文献[1]的基础上,又依据近年我所在本区获得的一些资料,从河口区的沉积物性、浅海区的海洋动力因素及近岸现代沉积作用三者的性状、作用过程和它们间的内在联系,作了新的论证和补充。 The scope of this article is shown in Figure 1. Figure 1 shows the modern silt-silt deposition from the low tide of the East China Sea to an isobath of about 60 m. In this area, two types of muddy silts on the inside and two silty muds on the outside were deposited around the isopach depth of 30m. Modern sediments are distributed in parallel with the shoreline. Based on the literature [1] and based on some data obtained in this area in recent years, this paper analyzes the characteristics of the sediments in estuarine areas, the marine dynamical factors in shallow seas and the sediments in nearshore, and their processes Between the internal relations, made a new argument and supplement.
