| 摘 要： | 中国城市大气污染日趋严重，汽车尾气污染所占比重越来越大。交通、道路、管制及气候条件等是影响城市机动车尾气排放的主要因素。本文根据机动车尾气研究的实际，研究了专题MGIS数据库结构， 并以广州为例，建立了基于GIS的城市机动车尾气扩散迁移预报系统，在此基础上实现了机动车尾气污染状况的可视化。

| Abstract: | Air pollution tends to be severer and severer in the cities of China. The proportion of gas pollution emitted by automobile tends to become greater. The conditions of traffic, road, management, climate are the main factors influencing city automobile emission. From the research prctice of this kind of automobile emission and by taking Guangzhou city as an example, the data structure of a special GIS is established and a prediction system based on GIS is developed for the advection and diffustion of automobile emission. The visualization for the distribution of pollutants emitted by automobile is realized |
