摘要： To gain a better understanding of the characteristics of air pollution of Changchun city, P. R. China, in summer, the analytical methods of geographical information system(GIS) and statistical analysis software SPSS were applied to the analysis of the monitored concentrations of SO2, NO2, and O3 in July of 2002 to 2004 in Changchun city. The results obtained show that the average hourly O3 concentrations in July 2002 and 2004 were higher than the first-level hourly standard of China. At the same time, the dynamic distribution of the O3 concentration and the relationship between the concentration of O3 and that of NOx were studied. The air quality evaluation result of Changchun city indicates that the southwest of this city was heavily polluted during the monitored period.
