以2006年8月在长江口外海域海试的悬浮泥沙数据资料为基础，采用相关分析和非线性回归分析方法，通过在经典泥沙剖面模型中引入潮流等过程的影响，改进了泥沙剖面模型的预测效果，将仅受水深一个因素控制的泥沙剖面模型拓展为与不同地点水文物理过程相关联的实用模型，并在整个研究区域验证了模型的有效性。%Based on the observation data of suspended sediment concentration (SSC), collected in the areas adjacent to the estuary of the Changjiang River in August, 2006, the correlation analysis and nonlinear regression were adopted. This paper introduced the tidal current to the classical vertical distribution model of SSC, which improved its predictive effect. This model could be practical, adding the hydrological process at different sites instead of only depth factor. At the same time, it had a better fitting effect in the whole areas.
