Aiming at the shortage of 3D visualization technology of ice flow evolution in the visual simulation of frozen rivers，we propose a visualization method based on the numerical simulation results of ice flow evolution by combining with MIKE21 and ArcGIS software.Meanwhile，we conduct numerical simulation and analysis of the ice flow evolution by model building，grid division，and boundary condition determination.Then we propose an extraction method of numerical simulation results for the visualization of the ice flow evolution，which can realize the fusion of the 3D visualization simulation scene and numerical simulation results of the ice flow evolution.The built simulation system of the flow evolution based on the spatial database and the attribute database can comprehensively display the simulation results such as the terrain，water flow，and embankment structure during the ice flow evolution.
