摘　　要：本文主要探讨复杂山地大气环境三维建模与数值仿真方法,介绍了三维数值地形图的概念及其表示方法,建立了相应的数据文件格式。针对某铀矿井尾气扩散实际问题创建了相应仿真模型,进行了仿真计算,并把仿真结果与实验结果进行了对比。从网格划分和仿真计算结果来看,证明这种方法简单且实用。The paper discusses the method of numerical simulation and three-dimensional modeling on complex mountainous atmospheric environment, introduces the conception of three-dimensional digital geographical map and the way to express it, buildings relevant formats of data file. Using the method, a simulated model was created for trail gas diffusion of real uranium mine. The simulation is conducted and the comparison between simulative result and experimental result has been made. The mesh and simulative result shows the method is simple and practical.
