ANALYSIS OF AIR QUALITY BASED ON STEPWISE REGRESSION METHOD-TAKE HUHHOT CITY FOR INSTANCE
Air quality index is a kind of evaluation index of atmospheric environment quality condition, and is simple and intuitive, and can be used for atmospheric environment quality assessment and pollution control and management.In this paper, air quality index was used for air quality analysis with the Hohhot PM2.5 monitoring data and meteorological data, and stepwise regression method was used to analyze the influencing factors of the quality of the air, and analyzed the influence of meteorological factor on air quality.The results shows that the main affecting factors of Hohhot urban air quality are the PM10, PM2.5, NO2and SO2, and the weather cooling, air dried and wind speed increasing will generate significant on air quality.
