摘　　要：利用GIS技术建立机动车污染仿真模拟系统,能够直观反映机动车污染的时空分布规律,为机动车污染控制研究提供有力的工具。以ArcGIS Engine为开发工具,通过属性数据和空间数据的连接,实现了武汉市机动车污染的数据查询和空间显示等功能,通过GIS和高斯扩散模型的集成,分析了武汉市交通污染分布,为机动车污染的控制提供了技术支持。该系统能对武汉市机动车污染物的排放进行实例分析。The system for vehicle emission based on GIS technology, which is used to illustrate the spatial distribution of emission dynamically and visually, can provide a powerful tool for the study of vehicle emission in emission control strategy. With ArcGIS Engine as the main development tool of the simulation system for Wuhan Vehicle Emission, the spatial and attribute data were joined to achieve the functions of data operation, graphical expression, dynamic query, and basic spatial analysis. This simulation system, which integrated GIS and Gauss dispersion model, helped us make the study of the regularity of vehicular emission distribution and provided technology support for the control of vehicle emission in Wuhan.
