摘要
针对目前松花江流域突发水污染日益严重,水污染可视化模拟不足的情况,基于可视化技术,研究水质模型与3S集成环境的融合方法与途径,构建了松花江突发水污染可视化模拟系统,实现了水质模型计算数据的动态可视化展现。着重介绍了三角网的构建和水质数据的拟合。以2005年松花江水污染为例,模拟了污染物的扩散和迁移过程,证明了该系统的有效性。
Aiming at the pollution of Songhua river basin getting more and more serious, and the shortage of water pollution visualiza- tion simulation, this paper based on the visualization technology, researches the method of the integration of water quality model and 3S environment, constructs the pollution visualization simulation system of Songhua river, realizes the dynamic visual show of the calcula- tion data of water quality model. This paper mainly introduces the construction of the triangle nets and the water quality data fitting. Tak- ing the pollution of the Songhua river in 2005 for example, the process of the diffusion and migration of pollutants is simulated.
