应用沉积物粒径趋势分析方法,研究了南黄海中部细粒沉积区的沉积物输运趋势.结果表明,在南黄海中部（123.4°E,35.1°N）左右的位置可能存在沉积中心,周边沉积物具有向这个沉积中心输运的趋势.这种沉积物输运和沉积格局受黄海气旋型环流（包括黄海冷水团）和冷涡的控制.本研究表明,沉积物粒径趋势分析方法在陆架大范围细颗粒沉积区内有着广阔的应用前景. The tendency of sediment transport in the fine-grained sedimentary area in the central part of the southern Yellow Sea was studied by means of sediment particle size trend analysis. The results show that there may be sedimentary centers around the central part of the southern Yellow Sea (123.4 ° E, 35.1 ° N) Sediment has the tendency to transport to this sedimentary center.The sediment transport and deposition pattern is controlled by the cyclone of the Yellow Sea (including the Yellow Sea cold water mass) and the cold vortex.The present study shows that the trend of sediment particle size is analyzed on the shelf A wide range of fine particle deposition area has a broad application prospects.
