| 摘 要： | 利用2014年5月~2017年12月的成都市环境空气质量监测资料,分析了成都市空气污染情况及污染物浓度时空变化特征。结果表明:成都市空气质量以优良天气为主,市区的首要污染物以PM2.5为主,郊区以O3为主;灵岩寺监测点的PM2.5,PM10,NO2和CO四种污染物的质量浓度低于成都市区各监测点,O3的质量浓度高于成都市区各监测点,SO2的质量浓度值与成都市区各监测点相差不大;成都市各监测站点六种污染物质量浓度具有明显的年际变化、季节变化、月变化和日变化趋势,且成都市区各监测点的变化趋势比较一致。

| Abstract: | Based on environmental air-quality monitoring data from May 2014 to December 2017,the spatial and temporal variation characteristics of air pollution were analyzed in Chengdu.The results showed that the air quality of Chengdu was dominant by good days,and the primary pollutant was PM2.5 in urban area and O3 in rural area.The rural concentrations of PM2.5,PM10,NO2 and CO at Lingyansi atmospheric background monitoring station were lower than that from urban.The concentration of O3 from rural was higher than that from urban.The concentrations of SO2 were similar in urban and rural areas.The concentrations of six pollutants in each monitoring station in Chengdu had obvious interannual,seasonal,monthly and diurnal variation trends,and the variation trends in each monitoring station in Chengdu urban area was comparatively consistent. |
