摘　　要：为提高邕江水污染预警预报能力,采用四边形网格法对邕江河道进行空间离散化,选择二维瞬时排放水质模型与GIS集成,实现邕江突发性水污染事故的模拟,并最终实现模拟结果的动态演示。模拟结果表明,该方法有效反映了污染物的时空分布状况,为邕江水环境保护和突发性污染事故的处理提供有力的决策支持。In order to improve early warning and forecast capacity of Yi-river water pollution, it made the spatial discretization by quadrilateral mesh method, and integrated the model of GIS and the twodimensional instantaneous discharge water quality, achieved to simulate sudden water pollution, and realized dynamic visualization of pollution simulating results ultimately. The results show that it reflected the space-time distribution of pollutants effectively, and provided a powerful support for water environmental protection and treatment of water pollution accidents in Yi-river
