摘要

Air pollution has become the most concerned regional environmental problem in China at present.According to the data of typical cities in Shandong Province from January,2014 to December,2015,the air quality status,pollution status and spatial variation characteristics of air pollutants were classified and analyzed,thereby providing a scientific basis for air pollution control.The conclusions of this study are as follows:(1)PM 2.5 was the most important atmospheric pollutant in Shandong Province;(2)Qingdao had the best air quality with a good air quality rate of 73.7%,while Jinan had the worst air quality with a good air quality rate only of 31.3%;and(3)the days with heavy pollution were mainly concentrated in winter,mainly due to coal-fired heating in winter.
