摘要: 利用CALPUFF模拟了2006年1月5日沈阳地区大气污染物扩散。结果表明,CALPUFF能够直观、真实地模拟大气环境中污染物浓度的分布。污染物扩散的范围与风速相关,风速大时污染物扩散的范围大,风速小时污染物扩散的范围小。当污染物扩散的范围大时污染源附近的污染物浓度值小,污染物扩散范围小时污染源附近的污染物浓度大。其中,日平均浓度的分布受平均风场和地形的双重影响,实时浓度的分布主要受风场的影响。

Abstract: The diffusion of air pollutants on January 5, 2006 in Shenyang was simulated by CALPUFF. The results indicate that the distributions of pollutant concentrations in the atmosphere can be simulated intuitively and really by CALPUFF. The diffusion scope of pollutants is related to wind speed. The larger wind speed is, the wider the diffusion scope of pollutant is, and vice versa. When the diffusion scope of pollutant is larger, pollutant concentrations around pollution source is smaller, and vice versa. The distributions of daily average concentrations are influenced by wind filed and topography. However, the distributions of real-time concentrations are influenced mainly by wind field.
