本文基于2013年南昌市大气自动监测系统的数据，分析了南昌市PM2.5、PM10污染情况。结果表明，PM10年均浓度为115.1μg/m3，PM2.5年均浓度为69.3μg/m3，均未达到国家空气质量二级标准；SO2及NO2的年均浓度达到或接近国家空气质量二级标准。南昌市城市大气污染呈现明显的季节变化特征，2013年全年达标优良率为60.8%，南昌城市空气质量与《环境空气质量标准（GB3095-2012）》二级标准的要求仍有很大差距。
本文基于2013年南昌市大氣自動鑑測繫統的數據，分析瞭南昌市PM2.5、PM10汙染情況。結果錶明，PM10年均濃度為115.1μg/m3，PM2.5年均濃度為69.3μg/m3，均未達到國傢空氣質量二級標準；SO2及NO2的年均濃度達到或接近國傢空氣質量二級標準。南昌市城市大氣汙染呈現明顯的季節變化特徵，2013年全年達標優良率為60.8%，南昌城市空氣質量與《環境空氣質量標準（GB3095-2012）》二級標準的要求仍有很大差距。

Based on the data from air automatic monitoring system, the paper analyzes the pollution of PM2.5 and PM10 in Nanchang in 2013. The results show that the annual average concentration of PM10 was 115.1μg/m3 and that of PM2.5 was 69.3μg/m3, which are failed to meet national secondary air quality standards. The annual average concentration of SO2 and NO2 met or approached to the national secondary air quality stan-dards. The urban pollution showed a feature of obvious seasonal variation. The pass rate of air quality in 2013 was 60.8%. PM2.5 is the main part of PM10, and there was a good correlation between PM2.5 and PM10. There exists a significant gap between the reality and the requirements of the secondary standard of the ambient air quality stan-dard (GB3095-2012).
