摘　　要：本文基于Matlab,以某企业高架点源Pb污染扩散为例,采用高斯扩散地面浓度模式计算了下风向区域的地面浓度,并绘制了浓度等值线分布图,识别出了下风向区域内受影响的村庄,为Matlab在高架点源大气污染扩散模式中的应用提供了范例。Matlab is specialized at numeric calculation and processing capacity,being applied in many fields extensively. In the present work, as an example, diffusion of Pb discharged by a high-elevated point source of an enterprise was taken. Basing on Matlab,ground concentrations of Pb in the downwind region were calculated using Gauss ground diffusion model,and contour map of ground concentration was plotted. According to the contour map, the affected villages in the downwind region of the high-elevated point source were recognized. The present work provided an example for the application of Matlab in air pollution diffusion model for high-elevated point source.
