| 摘 要： | 以1998年以来定点实测含沙量资料为基础,结合1996-2007年不同时刻卫星遥感影像资料对洋山港附近海域悬沙分布特征及运动规律进行分析,结果表明:洋山港海域含沙量存在着明显的季节变化;潮差越大,水体紊动越强,水体含沙量越高;洋山港水域含沙量明显高于其周围的水域,特别是在大小洋山岛链之间,呈现由北向南、由东向西逐渐增大的趋势;"峡岛效应"也是引起高含沙量一个重要原因;长江入海泥沙直接扩散对洋山港水体含沙量的影响较小,研究区域水体含沙量的大小主要取决于波况及潮流对当地浅滩的掀扬及输送.

| Abstract: | Based on the observation data of suspended sediment concentration since 1998, using the remote sensing image from 1996 to 2007, the distribution and movement tendency of suspended sediment and the influence of sediment movement in the Yangtze Estuary are analyzed. The results shows: (1) there is seasonal, temporal and spatial change at the distribution of suspended sediment concentration; (2) the change of suspended sediment concentration are controlled by tidal range; (3) suspended sediment concentration o... |
