一个实用的高速公路大气扩散模式

在高斯线源扩散模式的基础上，建立了一个适合高速公路大气污染源扩散特点的模式，并以沈阳环城高速公路环境影响评价中的应用为例，说明该模式的实用性和优越性．在建立该模式的过程中，应用了国外关于公路扩散试验的成果来确定和修正模式中的扩散参数．

A Practical Highway Atmospheric Diffusion Model

In order to predict the automobile pollution of the highway,a highway atmospheric diffusion model-a special Gaussian line source model is set up in the paper.The data of a foreign highway pollutant diffusion experiment are used to modify the diffusion parameter of this model for the deficiency of this kind of data in China.This model has been used in the environmental assessment of the highway around Shenyang city,and the results are satisfactory.
