摘要
本文以唐山市2014年1月1日-2018年12月31日PM2.5、PM10质量浓度为研究对象,分析了唐山市大气颗粒物在时间上的分布特征。结果显示:唐山市大气颗粒物浓度整体呈下降趋势,但污染仍较为严重,具体表现为冬季>春季>秋季>夏季,以冬季污染最为突出。
Taking the mass concentration of PM2.5 and PM10 from January 1,2014 to December 31,2011 in Tangshan City as the research object,the distribution characteristics of atmospheric particulate matter in Tangshan City were analyzed.It is found that the overall trend of atmospheric particulate matter concentration in Tangshan City is decreasing,but the pollution is still heavy,which is characterized by winter>spring>autumn>summer,which is most prominent in winter.
