Groundwater simulation model can simulate the dynamic characteristics of groundwater. GIS has powerful spatial data processing and analysis functions. Establishing an integrated system of groundwater simulation model and GIS will be helpful for popularization and application of groundwater simulation model and decision analysis. This paper discusses in detail the establishment of groundwater simulation model supported by GIS. The interactive subdivision method not only improves the modeling efficiency, but also takes full account of the hydrogeological conditions in the computational domain so that the effect of the generated grid cells is more satisfactory. In this paper, This method is applied to simulate groundwater simulations in Beijing, greatly improving work efficiency.
