为研究围垦工程对南黄海辐射沙洲海域潮流和泥沙的影响,基于嵌套的江苏省沿海二维水动力泥沙数学模型,模拟了江苏省沿海的潮流分布及南黄海辐射沙脊群海域的悬沙分布,分析并预测了远期围垦工程对潮流、悬沙的影响。结果表明,围垦工程改变了水沙环境,除个别海区,潮流动力大多有所减弱;除东沙东西两侧、条子泥南侧含沙量微增外,整体含沙量有所减小,含沙量明显减小的区域为条子泥北侧,为辐射沙洲海域围垦工程的建设提供了科学依据。
In order to study the influence of reclamation project on the tidal current and sediment in the radial sandbar area of the South Yellow Sea, based on the nested two-dimensional mathematical model of hydrodynamic sediment in the coastal area of Jiangsu Province, the tidal current distribution along the coast of Jiangsu Province and the radiation of sandy ridge in the South Yellow Sea Suspended sediment distribution, analysis and prediction of the long-term reclamation project on the tidal current, suspended sediment impact. The results show that the reclamation project has changed the water and sediment environment. In addition to the individual sea areas, the tidal motive force has mostly weakened; except for the east and west of Dongsha, the sediment concentration slightly increases on the south of the strip mud, The area with obvious decrease is the north side of the strip of mud, which provides a scientific basis for the construction of the reclamation project in the radiation sand barge area.
