摘　　要：采用组件GIS和Surfer,建立了基于高斯扩散的大气污染扩散预测系统,用以模拟工业点源污染对区域大气质量的影响,实现了工业点源下风向预测点污染物浓度的准确预测,并将生成的大气污染物扩散等值线图在MapObjects中与影响区的电子地图进行叠加,直观地显示了每个区域受此工业点源污染的程度,为城市空气环境问题的管理和决策提供了科学的依据。By the combination of GIS and Surfer,the predictive system of air pollution dispersion（APDS） is established on the basis of Gauss Dispersion Model to simulate the impact of industrial point source pollution on regional air quality.The system has an accurate prediction in the way of contour map on carrying out the appointed point of contaminant at downwind area.Furthermore,the contour map of air pollution dispersion can be overlapped with the effected digital maps in MapObject,directly showing the degree of contaminant of industrial point source in each region. This is of significant value for practical application, in an scientific way, to the management and decision-making of air and environment.
