摘要
珠江口表层沉积物类型复杂,但可归并为11种基本类型。通过其粒度参数分析,追溯本河口区域泥沙来源是以径流和落潮流下泄泥沙为主,海域来沙为辅。泥沙运移的基本形式是以悬移运动为主要,大量落淤在河口湾的泥沙经过淤落、搅动、掀起等形式的区域内部调整搬运,形成了珠江口海区的大面积悬移质细粒泥沙沉积。泥沙运移的基本趋势是在科氏力影响下及海岸流作用下向珠江口西岸运移。
The sediments are basically grouped into 11 types the in Pearl River estuary,even though they are complex. The grain-size parameter analysis showed that the sediments mainly originated from runoff and ebb current discharged sands,and were supplemented by sea sands.The suspended sand loads were transported and deposited in the Pearl River estuary.And further internal adjustment handling of stirring and lifting developed a large amount of fine-grain sediments.Finally,the sediments were basically tranported towards the west bank of the Pearl River estuary under Coriolis force and the coast flow.
