【摘要】:Based on daily newspaper of urban air quality and meteorological monitoring data in Shiyan City during 2014-2015,air pollution characteristics of industrialized city were studied,and change characteristics of air quality and impact factors were analyzed by combining weather data. Results showed that air quality of Shiyan City was dominated by grade-Ⅱand grade-Ⅲ weather,in which occurrence days of grade-Ⅱ weather accounted for 64.9% of statistical days,while grade-Ⅲ weather accounted for 17. 9%; air quality had obvious seasonal characteristics,and winter air quality was the worst,with AQI of 114. 1,while summer air quality was the best,with AQI of 70.6; primary pollutant was PM_(2.5),and annual average PM_(2.5),PM_(10) and AQI indexes were 0.059 μg/m~3,0.093 μg/m~3 and 85. 618; PM_(2.5),PM_(10) and AQI indexes were negatively correlated with temperature,water vapor pressure,low cloud amount,sunshine,wind velocity,rainfall,and were positively correlated with air pressure,total cloud amount,fog and haze.
