摘要
采用统计方法分析了2014-2019年大同市环境空气质量的变化特征,结果表明:大同市第一季度的空气质量与PM 2.5的含量呈现高度正相关;第二季度空气质量整体最好,但是臭氧含量最高;第三季度污染程度上升;第四季度的空气质量最差,与诸多污染物有关;同一年的空气污染物含量变化呈现出明显的规律性。
This paper analyzes the changes characteristic of ambient air quality in Datong city from 2014 to 2019 by using statistical methods.The results show that the air quality in the first quarter of Datong city was highly positively correlated with the PM2.5 content;the second quarter had the best air quality,but the highest ozone content;the pollution level increased in the third quarter;the air quality in the fourth quarter was the worst,related to various pollutants.The air pollutant content changes in the same year showed obviously regular.
