摘　　要：在现有的水体瞬时点源污染扩散元胞自动机模型的基础上,分析了基于元胞自动机进行瞬时点源污染物扩散漂移模拟分析的方法,结合河流速度分布特征,建立了河流污染扩散模型,采用该模型对汉江武汉段突发性水污染事故进行了动态模拟,以不同颜色显示不同污染浓度,预报了污染物质的漂移轨迹。The method of transient analysis of instantaneous point source pollutant dispersion drift based on cellular automata is analyzed according to the existing cellular automata model. Combined with the characteristics of river velocity, the models for river pollution spread is constructed. And the model is used to simulate the sudden water pollution accident in Hanjiang River in Wuhan. The different pollution concentrations are displayed in different colors, and the drift trajectory of pollutants are predicted.
