摘　　要：采用MM5-Models-3/CMAQ区域空气质量模拟系统,以2005年1、4、7和10月为模拟时段,对中国地区的SO2、NO2和颗粒物(PM)等大气污染物的浓度进行了模拟,应用卫星遥感数据,对包括NO2柱浓度和气溶胶光学厚度(AOD)等模拟结果进行了进一步的验证。从模拟结果与监测资料对比分析中可以看出,该模式能较好地模拟出几种污染物的空间分布格局,尤其是我国的京津冀地区,长江三角洲地区和珠江三角洲地区等三大经济圈的模拟结果与监测结果较吻合。中国地区的大气污染呈现出区域性的特征,且在时空分布上东西部地区存在明显的差异,经济发达地区的污染较为严重。CMAQ计算结果与卫星遥感数据有很好的相关性,该模拟系统对中国地区的大气污染物特征具有良好的模拟能力。MM5-Models-3/CMAQ was applied to simulate the distribution of SO2,NO2 and PM in China by taking the January,April,July,October in 2005 for example.The comparison between simulation results and monitoring data show that this model can simulate the spatial distribution patterns of pollutants preferably,simulation results and the monitoring results are identical,especially for the Beijing-Tianjin-Hebei region,Yangtze river delta and pearl river delta etc.In order to make up for the deficiency of monitoring data,the study applied satellite remote sensing data to the further verification of the simulation result,which include NO2 column concentration and aerosols optical thickness（AOD）.The results showed that experimental results of the CMAQ calculation results were highly correlated to those of the satellite remote sensing data;this simulation system is a very good way to simulate the characteristics of the atmospheric pollutants in China.
