摘要
为了解成都市西北延线大气污染物浓度变化特征,结合成都市环境空气质量监测大数据,选取沿线环境空气连续自动监测站点数据作为西北延线污染物浓度评判依据,分析了2016~2018年大气常规监测的6个参数月平均浓度的变化情况。结果表明:西北延线空气质量整体好转,大气污染物浓度基本呈下降趋势,其中臭氧、氮氧化物、颗粒物均具有明显变化特征。
In order to understand the variation characteristics of atmospheric pollutant concentration along the northwest extension line of Chengdu,combined with the large data of ambient air quality monitoring in Chengdu,the continuous automatic monitoring station data along the northwest extension line were selected as the basis for pollutant concentration evaluation,and the monthly average concentration variation of atmospheric routine monitoring six parameters from 2016 to 2018 was analyzed.The results show that the air quality of the northwest extension line has improved as a whole,and the concentration of air pollutants has basically shown a downward trend,among which ozone,nitrogen oxides and particulate matter have obvious change characteristics.
