摘　　要：AERMOD模型及CMAQ模式均可实现对大气颗粒物浓度的预测,其中AERMOD模型以预测点源和小型面源为主,也可通过设置矩阵实现对片区多个污染源的预测,CMAQ模式则适用于更大尺度空间模拟。对于规模较小的工业园区,两种模式均可达到预测效果。本文以昆明市海口化工园区为例,分别采用这两种模式对颗粒物(PM_(10))浓度分布进行预测,对结果进行对比分析,提出各自优势及特点,为园区规划环评大气模拟提供更多拓展思路。Both AERMOD model and CMAQ model can predict the concentration of atmospheric particulates.The AERMOD model mainly predicts point sources and small area sources as well as multiple pollution sources in the area by setting a matrix.The CMAQ model is suitable for larger scale spatial simulation.For small industrial parks,both models can achieve the prediction goal.Taking Haikou Chemical Industry Park in Kunming City as an example,these two models were adopted to predict the concentration distribution of particulate matter(PM_(10)) to compare and analyze the results,and identify their respective advantages and characteristics to provide more expanded ideas for atmospheric simulation of environmental impact assessment in park planning.
