| 摘 要： | 本文对2003年7月所采集的灌河口外179个沉积物样品(其中岸滩为61个,近岸浅海为118个),应用激光粒度仪进行了粒度分析,获得了粒径分布数据和矩法参数,据此将该海域沉积物划分为5种类型,其中主要为粉砂质砂和砂质粉砂;沉积物在河口附近的分布大体以灌河口主航道为中心,具有对称性特征;沙嘴附近的沉积物组成较为复杂,来源较多,表明其形成是波浪、潮流、沿岸流以及径流综合作用的结果。

| Abstract: | 179 surface sediment samples(61 from seashore and 118 from shallow sea) collected from Guanhekou sea areas are analyzed by using a Cilas940 L laser Analyzer.On the basis of the obtained grain size data and grain size parameters of these samples,the sediment around the Guanhe sea areas can be divided into five types and most of them belong to silty sandstone and sandy siltstone.The sediment spreads around the Guanhekou Estuary and the center of it was on the central sea-route.The sediment components were very complex and resulted from various processes such as the wave,tidal current,coast flow and the fluvial processes. |
