摘要
本文针对目前城市环境中大气污染扩散的可视化研究中存在的主要问题,利用大气点源扩散模型和GIS技术相集成的方法对点源污染扩散的可视化问题进行了探索。在研究中,首先在总体上介绍了点源扩散模型和GIS技术的集成框架,然后描述了大气点源扩散模型可视化实现的方法和过程,并给出了典型条件下的可视化结果图,它能够更加直观地表达大气点源扩散的动态可视化效果。
Visualization is a hot topic in geographic field. This paper aimed to solve the main problems existed in visualization of atmospheric dispersion, it integrated atmospheric point source dispersion model with GIS to study the visualization of the point source dispersion. In the paper, firstly it built the point source dispersion model and the integrated framework based on the GIS. Then, it gave the process of the visual expression of the point source dispersion model, and discussed the key question in the realization of visualiza- tion. Finally, it gave the results of prediction based on the point source dispersion model to express dynamic effect of the dispersion in practice more vividly.
