Abstract: In this paper, based on the monitored data for Shanghai’s environmental quality in 2013, principal component analysis(PCA) was adopted to analyze six pollutants in the areas surrounding the nine state-controlled monitoring stations in Shanghai, aiming at obtaining the relationships between the six pollutants and the spacial-temporal characteristics for the air quality in Shanghai. Two principal components were derived from PCA. The first component was represented by the information of five pollutants: PM10, PM2.5, CO, SO2 and NO2. The second component was represented by the information for the pollutant O3. The PM2.5, PM10 and O3played a leading role affecting air quality. Through computation, it concluded that the areas with the worst air quality in 2013 in Shanghai were Shanghai Normal University’s monitoring station in the Xuhui District, the monitoring station in the Jingan District and the Sipiao monitoring station in the Yangpu District. In contrast, the air quality was the best in the Chuansha and the Zhangjiang monitoring stations in the Pudong New District. The air quality for Shanghai was better in autumn and summer than that in winter and spring.
