摘　　要：将INTEX-B排放源应用到空气质量模型Model3-CMAQ中,对中国地区对流层NO2的浓度分布进行了数值模拟,并与OMI卫星对流层NO2资料进行了对比和验证。结果表明:将INTEX-B排放源应用到Model3-CMAQ模式,模拟的NO2浓度在中国地区的分布、季节变化规律与卫星资料所得结果一致。敏感性试验表明,工业及电厂排放对NO2的浓度贡献最大,而交通排放的贡献相对较小,两种排放均主要集中在京津、长江三角洲等经济发达地区。The tropospheric NO2 concentrations in China region were simulated by applying INTEX-B emission source to the third-generation air quality modeling system（Model3-CMAQ）.The simulation results were compared and validated with the tropospheric NO2 column concentration data from ozone monitoring instrument（OMI）.The results indicate that the distributions and seasonal variations of the simulated NO2 concentrations by applying INTEX-B emission source to Model3-CMAQ are consistent with the observational values from the satellite over China region.The sensitivity tests indicate that the effects of industrial emission and power plant emission on NO2 concentrations are the most significant,and the effect of traffic emission is far lower than that of industrial emission and power plant emission.Both emission means are mainly concentrated in developed regions of economy such as Beijing,Tianjin and the Yangtze River delta.
