汽车尾气污染地理显示系统的开发研究

A GIS-based Display System for Vehicles Emission Dispersion

利用汽车尾气扩散模型和地理信息系统技术,建立起汽车尾气污染地理显示系统软件(以广州市为例),用户在软件界面上确定选取点或区域后,该软件即通过内部程序进行分析、计算并在界面上形象地表示出汽车尾气污染扩散对该点或区域的影响。本系统能够直观、快速地反映城市交通的大气污染状况,为环境管理和决策部门提供有益参考。

By use of a vehicles emission dispersion model and GIS, software with graphic interfaces is set up. The users can display vehicles emission pollution in terms, of pollutants concentrations status when selecting the point in the interface. Moreover, influences of the emission dispersion on ambient air quality in the selected point or area can be quickly displayed in the interface through analysis and calculation by the software procedure.
