摘要

Air pollution is a hot issue of current research. In recent years, air quality of China shows the significantly declining tendency. To explore tempora卜spatial distribution rule of ai「quality status of China not including Hongkong，Macao and Taiwan，air quality indexes (AQI) of 31 provincial capitals of China in 2014 were taken as research objects. By literature retrieval, data excavation, statistic analysis and logical reasoning, temporalspatial distribution rule of air quality status from 31 provincial capitals of China and its macroscopic origin were deeply studied. The results showed that： firstly, more than 80% of provincial capitals in China had the phenomenon of air quality exceeding standard to different degrees in 2014； secondly, air quality status of China showed significant spatial difference characteristics(P<0.05) ； thirdly, rapid development of the three major industries, promotion of urbanization process and growth of urban population were important causes for bad air quality of 31 provincial capitals of China.
