| 摘 要： | 通过系统采集海底表层沉积样品进行粒度测试分析，对现代莱州浅滩地区的沉积类型、粒度特征、泥沙搬运方式、运移趋势及沉积动力、沉积机制进行了研究。结果表明，莱州浅滩是形成于松散碎屑堆积海岸岬角岸外的砂砾质水下沙洲／沙脊，它的形成深刻改变了浅滩地区原有的沉积动力和机制，在浅滩两侧海域各自形成了大致对称的潮余环流，分别与两个主要...

| Abstract: | By testing granularity of surface sediment samples, we studied sedimentary types, granularity characteristics, sediment transporting pathway, sediment migration trends, sedimentary dynamic and morphodynamic model of the Laizhou shoal. The results showed that the Laizhou shoal is sand banks/ridges made of loose clastic sediment, the formation of the shoal has profoundly changed the original sedimentary system through circulations of two symmetrical tidal residual current on both sides of the shoal, which corresponded to two sedimentary depocenters dominated by saltation and suspended load, respecitvely. Morphodynamic model of Laizhou shoals is different from the existing models about headland associated shoals, and this shoal represents a new type of headland associated sand banks/ridges. |
