摘　　要：为研究EFDC模型的GIS可视化,采用EFDC模型对恩县洼蓄滞洪区二维洪水演进过程模拟,根据工程实际需要改进EFDC模型输出项,输出洪水历时等EFDC模型原来未涉及的输出项,并将EFDC模型与GIS耦合。通过与EFDC模型展示效果对比,GIS平台的展示效果明显优于EFDC二维网格展示效果,能更好地模拟二维洪水演进过程,为蓄滞洪区防洪评价、防洪决策、抢险等提供技术支持和研究方法。To do research on the GIS visualization of EFDC model ,EFDC model is used to simulate two-dimensional flood routing in Enxianwa Detention Basin .According to the actual need of improving output items ,it can output items such as flood duration which EFDC model itself is not involved .And then GIS is coupled with EFDC model .Comparing the display of two-dimensional grids in EFDC model ,the display of GIS is obviously better .So it can simulate two-dimensional flood routing process better and provide technical support and methods for flood assessment ,flood control decision-making and dealing with an emergency in the flood detention basin .
