| Abstract: | With air quality daily mean data provided by Hohhot environmental monitoring station, the daily variation of air quality of third-level（slight pollution） or above from 2007 to 2012 were analyzed. The results showed that the days of third-level（slight pollution） or above were decreased and the air quality was improved year by year in recent six years in Hohhot according to Ambient Air Quality Standard（AAQS）（GB3095-1996）, and the interannual and seasonal change of chief contaminant of third-level（slight pollution） or above were prominent.
