    摘要
  • 根据莱州湾内小清河口海域的悬沙和底床的粒径、含沙量及潮流的观测资料,探讨了该海域的悬沙运动特征。研究结果表明,含沙量总体趋势为由岸向海逐渐增大,并呈现出北高南低的分布特点,其中河口东北海域为含沙量高值区。近岸悬沙主要受底质沉积物的影响,而离岸较远海域悬沙可能主要是源于相邻浅水区海域悬浮颗粒在流场作用下从外海运移而来。河口北部海域表底层含沙量基本一致;而南部海域底层含沙量远大于表层。大潮含沙量远大于小潮含沙量,含沙量存在随潮流增大而增大的总趋势。小清河口泥沙主要来源于黄河口再悬浮泥沙的输运及近岸浅滩局部搬运。
    Based on observation data of suspended sediment and bed sediment grain sizes, suspended sediment concentration(SSC), and tidal current,we have studied the characteristics of suspended sediment transport near Xiaoqing estuary in Bohai Sea. The research results show that the SSC increases gradually from the seashore to the offshore area in the whole research region. The north part is higher than the south, and the northeast of estuary is the highest. The inshore suspended sediment is mainly influenced by local bed sediment, and the offshore suspended sediments possibly come from the suspended particles of the adjacent region. The surface sediment concentration is similar to the bottom in the north, but the bottom one is much larger than the surface in the south. The SSC of spring tides is much larger than that of neap tides, and the SSC increases with tidal current. Sediment is mainly from inshore sediment transport in Xiaoqing estuary.
