摘要
在常用的高斯扩散模型基础上,简化了一些参数取值并考虑了在交叉口等处的特殊情况,建立了汽车尾气扩散模型;再将模型和地理信息系统技术相结合,建立起《广州市汽车尾气污染扩散仿真系统》模拟软件。用户在软件界面上确定选取点后,该软件即通过内部模型库和数据库进行分析、计算并在界面上形象、简捷地表示出汽车尾气污染扩散对该点的影响状况。本文简介了系统原理及其实现,并将模拟结果与实测数据进行了比较,显示两者具有良好相关度。
A vehicle emission dispersion model is developed on the basis of modified Gauss dispersion model, and the model especially deals with the dispersion in the intersection by a submodel. By the combination of the model and Geographic Information System, a software with graphical interfaces is built, which could display the status of pollutant concentration arise from the vehicles emission directly by user selecting the point in the interface and then procedure calculating. In addition, the comparison of the calculated data with the observed data is given, and the result shows a favorable correlation.
