| 摘 要： | 结合2006年最新的气溶胶排放源资料,以NCEP/NCAR再分析资料为气象场,驱动大气化学传输模式MATCH（Model of Atmospheric Transport and Chemistry）,模拟了2006年中国地区硫酸盐、黑碳和沙尘气溶胶的质量浓度分布及其季节变化。模拟的气溶胶光学厚度（AOD）结果与CSHNET观测网数据比较分析后发现,基于21个观测站的61组月平均数据与相应模拟结果的相关系数为0.63。模拟结果表明：2006年中国地区硫酸盐气溶胶高值区主要分布在中国的四川盆地、华北及长江流域等工业较发达地区,而且具有明显的季节变化,四川盆地及长江以南地区,硫酸盐气溶胶1月份浓度高于7月份,长江以北的大部分地区,7月份浓度高于1月份;黑碳气溶胶主要分布在黄河、长江中下游地区及华南等地区,1月份浓度高于7月份;沙尘气溶胶主要分布在内蒙古中部沙漠地区,4月份浓度最高,7月份次之,其他月份较少。 |

| Abstract: | The Model of Atmospheric Transport and Chemistry(MATCH)is used to simulate the distri-bution and seasonal variation of aerosols over China in 2006,by taking the latest source emission data and NCEP/NCAR reanalysis data as its initial conditions. The aerosol optical depth (AOD) obtained by MATCH is compared wim the CSHNET(the Chinese Sun Hazemeter Network)observational data.The =0.000 1).The results indicate that the high concentrations of sulfate are mainly located in Sichuan Basin,North China and the middle and lower reaches of the Yangtze River,and that sulfate loading is higher in July than in January in the north part of China and is opposite in the south part of China.The results also show that higher concentrations of black carbon aerosol appear in the middle and lower tea-ches of the Yangtze River and the Yellow River and the maximum values are higher in January than in July. The center with high concentration of dust aerosol is located in Inner Mongolia of China.The highest concentration of dust aerosols appears in April, with the secondary maximum value in July. |
