摘　　要：基于2013—2018年镇江市4个站点常规大气污染物数据,研究镇江区域空气质量状况和大气颗粒物时空污染特征。结果表明:2013—2018年,镇江市空气质量总体良好,多年均达标,达标率为64%;大气颗粒物(PM_(2.5)、PM_(10))年平均质量浓度总体波动下降,具有明显的季节变化特征,冬季>春季>秋季>夏季,其中7—9月大气颗粒污染较轻,12月、1月污染较重。首要污染物以大气颗粒物污染为主,其中PM_(2.5)占比高于PM_(10);AQI指数和大气颗粒污染的空间聚类表明,新区办事处站有别于其他3站。Based on the conventional air pollutant data of four stations in Zhenjiang City from 2013 to 2018,this paper studied the air quality status and temporal and spatial pollution characteristics of atmospheric particles in Zhenjiang.The results showed that from 2013 to 2018,the air quality of Zhenjiang City was generally good,and the average rate of reaching the standard for many years was64%;The annual average mass concentration of atmospheric particulates (PM_(2.5)、PM_(10))fluctuates and decreases generally,with obvious seasonal variation characteristics.Winter>spring>autumn>summer.The pollution of atmospheric particulates was light in July September,and heavy in December and January.The primary pollutant is atmospheric particulate matter,with PM_(2.5)accounting for more than PM_(10);The AQI index and the spatial clustering of atmospheric particle pollution show that the New Area Office Station was different from the other three stations.
