针对2014年8月南京国际青年奥林匹克运动会期间周边地区污染源的减排控制研究，将2010-2012年8月NCEP/NCAR 的6 h 再分析资料作为驱动场，利用 WRF 模式处理得到时空尺度更为精细的风场资料，结合南京奥体中心观测点的颗粒物及气体污染物浓度资料，通过相关分析以及合成分析，诊断得到了8月影响南京地区主要污染物的周边源区及其关键输送通道。结果表明：尽管8月青奥会时段南京地区主导风为海洋吹向大陆的东南风，但影响南京地区主要污染物（SO2， NO2，PM10）浓度的外源及其主要输送路径各有不同。来自于南京西南部江西、湖南、湖北等地的较远距离输送是对南京地区SO2浓度影响的关键通道；来自于南京正南方向（安徽、浙江一带）的近距离输送是对南京地区 NO2浓度影响的关键通道；来自于南京西南部（湖北一带）的中远距离输送是对南京地区 PM10浓度影响的关键通道。

In order to focus on pollutant emission mitigation during the Nanjing Youth Olympic Games in August of 2014,the fine wind field data were obtained by the WRF model using the 6 hours interval NCEP/NCAR reanal-ysis data in August during 2010 to 2012 as driving field.Combing the observational particles and air pollutants con-centration data,the surrounding source regions of main pollutants and its transport pathway that influences the air quality in August in Nanjing area were diagnosed by methods of a correlation analysis and a composite analysis. The results show that the dominant wind in August is southeast from sea to inland during Nanjing Youth Olympic Games,while the source area and transport pathway influencing the concentrations of main pollutants(SO2 ,NO2 , PM10 )differ.The southwestern air flow with high SO2 concentration from Hu′nan,Jiangxi and other regions has a great influence on the concentration of SO2 in Nanjing;the southern air flow transport from Anhui and Zhejiang largely contributes the high NO2 concentration in the ambient air in Nanjing;the southwestern pathway connecting the emission sources over Hubei is a key route in the PM10 transport to Nanjing urban area.
