摘　　要：根据杭州湾、长江口流场和物质输运的特点，引进正交曲线网格版本ＥＣＯＭ模型，并对斜压梯度力和物质对流扩散的计算作了改进，建立了一个以杭州湾和长江口为整体的三维联合模型，用于潮流、余流和物质输运的计算和研究．A 3-D numerical model is set up in a large domain covering the Hangzhou Bay and Changjiang Estuary based on ECOM - si model in orthogonal curvilinear coordinates. The numerical schemes for the baroclinic gradient terms and convective terms are improved according to the characteristics of velocity field and mass transport in the area. The model is validated by simulating residual currents and salinity transport in the Hangzhou Bay and the Changjiang Estuary.
