围垦工程对江苏省南黄海辐射沙洲海域潮流和悬沙的影响

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。

Influence of Reclamation Project on Tidal Current and Suspended Sediment of Radial Sand Ridge System in South Yellow Sea of Jiangsu Province

To study the influence of reclamation project on tidal current and sediment of radial sand ridge system in the South Yellow Sea, based on nested Jiangsu coastal 2D mathematical model of hydrodynamic and sediment transport, the tidal current distribution of Jiangsu coast has been simulated. Then the distribution of suspended sediment of radial sand ridge system in the South Yellow Sea has been depicted. Finally, the impact of reclamation project on the tidal current and suspended sediment has been analyzed and predicted. The results show that the hydrodynamic and sediment environment has been affected after reclamation project; in addition to individual areas, the tidal current has diminished; the whole suspended sediment concentration has reduced except for east and west sides of Dongsha, south side of Tiaozini. The area of suspended sediment concentration significantly reduced in the north side of Tizozini. Therefore, it provides scientific basis for reclamation project construction.
