摘要
通过潮流和表层沉积物粒度参数等实测资料,对舟山群岛海域表层沉积物的运移趋势、净输运通量以及起动流速进行了初步分析。结果表明,舟山群岛对研究区表层沉积物分布影响明显;舟山群岛海域表层沉积物整体由湾口向外海输运,平均日单宽输沙通量由杭州湾内向外海迅速减小;从杭州湾向外海,泥沙起动越来越难,单纯潮流对表层沉积物再悬浮作用相对较弱。
Based on the measured data, transport trend, net transport fluxes and incipient velocity of surface sediments in Zhoushan Archipelago sea area are analyzed in this article. Results show that surface sediment distribution is significantly affected by the Zhoushan Archipelago. The surface sediments are mainly transported from Hangzhou Bay to offshore area; meanwhile, the net transport fluxes per day rapidly decrease towards the offshore area. Surface sediments become more and more difficult to he activated from the Hangzhou Bay to the offshore area. Tidal current plays a less important role in resuspension of surface sediments.
