摘要
以上海宝山区大厂镇突发性污染泄漏预警系统这一基于高斯扩散的大气污染扩散空间信息系统为例,将点源大气扩散模式——高斯模式与ArcGIS的有机结合,初步探讨了突发性大气污染的预警研究。预警系统具有相当的灵活性,可以通过多种插值方法有效地模拟底图上任一点的突发性大气污染扩散状况。与此同时,扩散模式与GIS软件的有机结合,实现了系统的可视化,简化了模式输入,而且使得系统具有了空间分析功能,是一次不错的尝试。
A tentative study is conducted to early warn the emergency pollution in terms of developing an air pollution dispersion system, which combines elevated Gauss dispersion model with the software of ArcGIS, taking the sudden leakage pollution warning system in Dachang town, Shanghai Baoshan district as an case. The system is very flexible because it can be used to simulate air pollution dispersion from any place on the base map. In addition, with the help of GIS software, the system simplifies the data input by realizing visualization and also has the function of spatial analysis
