摘要：针对常用的大气颗粒物(PM₁₀、PM_2.5)浓度计算模式计算结果偏差较大的问题,由太原市城区例行监测的PM10浓度估算出燃煤电厂导致的大气颗粒物(PM₁₀、PM_2.5)浓度推算值,使用AERMOD和CALPUFF模式计算燃煤电厂排放源导致的大气颗粒物浓度,对大气颗粒物浓度的计算值与实测值进行了比较分析与评估。结果表明:在城市区域,性能较佳的大气颗粒物浓度计算模式是AERMOD模式。

Abstract：In view of the larger deflection of the air particles concentration calculated by existing calculation models,estimating the quasi measured concentration of particles(produced by coal-fired power plants in Taiyuan city) from PM₁₀ actual monitoring values of Taiyuan routine monitoring, the air particle concentration were calculated by the AERMOD and CALPUFF model for source of coal-fired power plants, the calculation concentration and measured air concentration of the particles were compared and evaluated. The results showed that in urban areas,the better calculation model of air particle concentration is AERMOD mode.
