【Abstract】Regional changes of urban air quality and meteorological effects were statistically analyzed based on environmental monitoring and meteorological observation data from 2013 to 2016 in the paper. In the recent four years, annual average concentrations of SO2, NO2, O3_8h, PM10, PM2.5 and CO were respectively (20.78 ± 19.71), (28.32 ± 9.59), (107.59 ± 27.54), (67.56 ± 34.32), (42.53 ± 24.52) μg/m3 and (0.74 ± 0.22) mg/m3 in Guiyang. Except for concentrations of SO2 close or exceeding central and eastern China, other air compositions kept in low levels. Ambient O3 concentrations significantly increased, while other air pollutant level declined with the similar patterns of inter-annual, monthly and diurnal variations with central and eastern China. The significant differences of air pollutants existed among industrial, residential and suburban areas with industrial area > residential area > suburb for particulate matter, SO2, NO2 and CO as well as suburb > residential area > Industrial area for surface O3 concentrations, reflecting impact of human activities on air quality. Air compound pollutants O3 and PM2.5 presented positive correlation in summer and but negative correlation in winter. Air temperature, boundary layer height, solar radiation and air pressure had significant impacts on pollutant concentrations, while relative humidity and wind speed had the weak influences, differently from wind speed dominating changes of air quality in central and eastern China.In summer, rainy season in Guiyang, PM2.5 hygroscopic growth was weak in light or moderate precipitation intensity with the obvious aerosol wash-out by large and heavy rainfall; both PM2.5 hygroscopic growth and removal of precipitation were more remarkable in the dry and cold winter.
