| 摘 要： | 采用HAMSOM三维正压水动力模型结合粒子追踪的悬浮颗粒物输运模型模拟了渤、黄、东海悬浮物质量浓度冬、夏季变化。模拟结果显示,潮流和底质对悬浮物质量浓度的分布有决定性的作用,沉积物再悬浮对悬浮物质量浓度分布影响大,冬季尤为显著。莱州湾中西部和渤海湾南部悬浮物终年维持高质量浓度,古黄河口冬季再悬浮物的质量浓度高于其它季节的。长江口附近悬浮物终年维持高质量浓度,夏季长江口东北悬浮物的质量浓度高于冬季的,浙江沿岸冬季悬浮物的质量浓度高于夏季的。

| Abstract: | In this paper,the three-dimensional barotropic hydrodynamic model(HAMSOM) and the suspended particle transport model(SPM) are used to simulate the variations in winter and summer suspended material concentrations in the Bohai Sea,Yellow Sea and East China Sea.It is shown from the simulated results that the tidal current and bottom sediment play a decisive role in forming the suspended material concentration distributions,the sediment resuspension has considerable influence on the suspended material concentration distributions,and the influence is especially significant in winter.The high suspended material concentrations are maintained in the central and western Laizhou Bay and the southern Bohai Bay all the year round,and the resuspended material concentration near the abandoned Yellow River estuary in winter is higher than that in other seasons.The high suspended material concentration near the Changjiang River estuary is maintained all the year round,the suspended material concentration in the sea area northeast of the Changjiang River estuary in summer is higher than that in winter,and the suspended material concentration along the Zhejiang coast in winter is higher than that in summer. |
