包头市机动车排放污染物扩散的研究

Study on Diffusion of Pollutants Discharged by Motor Vehicle in Baotou

本文以包头市为例,对城市汽车污染扩散的影响因素进行了简要分析,采用街道峡谷汽车污染扩散模型,得出了包头市典型街道小寨街道的机动车污染扩散公式,利用OSPM模式计算了包头市典型街道区域内的机动车排放污染物的浓度,其中小寨街道循环区内平均总浓度为0.952mg/m3。

This article takes Baotou for example to analysis the factors affecting the diffusion of the pollution urban motor vehicles discharged. It＇s obtained that the pollutants diffusion formula of motor vehicles in typical street-Xiaozhai using street canyon pollution diffusion model. OSPM model was used to calculate the concentration of the pollutants that the urban motor vehicles discharged in Baotou, among which the average total concentration of Xiaozhai street cycling area was 0.952mg/m3.
