摘　　要：采用二分步法 ,从积分型方程出发 ,在有限控制体上建立守恒型差分格式 ,对二维浅水波方程进行求解 .求解线性代数方程组采用矩阵标识法 ,提高了计算效率 ,特别适合于流域大尺度水流的模拟 .计算网格采用无序编码方法 ,灵活方便 .算例表明 。By use of the time split method, a conservation difference formula is established to find the solution to the shallow water equation based on the finite volume control method from integral equations. The Matrix Mark Method, adopted to solve algebra equations, improves the efficiency of computation. With the disordering coding method, it is convenient to determine computational meshes. The result shows that the present method is suitable for the modelling of large scale flow patterns of broad lakes.
