摘　　要：从控制方程出发，以Ｇａｌｅｒｋｉｎ有限元法为基础，结合有限元法的较新改进，推导、建立了一个适合于浅水湖泊ＴＰ浓度分布计算的二维迎风有限元的数值模型，并将其应用于太湖。A new two dimensional upwinding finite element numerical model,suitable for modeling concentrations of total phosphorus(TP) in shallow lakes was derived,from the starting point of control equation,based on Galerkin finite element method and combined with the new development of the finite element method.The model was applied in Lake Taihu for the study of TP distribution in the lake water body.
