This research on the influence of sediment resuspension on the flux of materials in the margin of the East China Sea showed that the sediment resuspension rates, was 47.40%-79.18% in the surface layers, and 72.75%-96.96% in the bottom layers.The research confirmed that the Changjiang River runoff and the eddy area upwelling flow near 125°E were two important factors affecting the sediment resuspension in summer; the transformation of DOC to POC through the flocculation in the transitional region (123°-124°E) was also confirmed by comparison of the resuspension rate. The sediment resuspension was shown to be influenced by the seasonal factor, especially in the surface layer.
