Abstract：In the period of June 9 to June 14,2012,a serious regional air pollution event took place over the middle and lower reaches of Yangtze River.During the air pollution,there are significant differences in the pollution process of the four typical cities including Xuzhou,Nanjing,Hefei and Wuhan.The daily fire-point number derived from satellite data was examined firstly.Then urban historical weather data,air pollution index and NCEP reanalysis data were used for contrastive analysis of the pollution process of the four typical cities and furthermore the diffused track of pollutants that influences the cities was retrieved by the Hysplit-4 mode.The results illustrated that the city pollution level is affected by geography and weather conditions and the influence of the climate factors are primary influencing factors.It indicates that the reducing of urban environmental capacity leads to the increasing sensitivity of the city to pollution.Some proposals in prevention and control of urban and regional air pollution are put forward as well.
