J市2016年PM_(2.5)浓度不降反升原因探析
|
摘要
根据2015、2016年J市5个空气质量自动监测点位PM_(2.5)相关浓度数据,对J市2016年PM_(2.5)浓度升高原因进行了探析。结果表明,3、5、6、11、12月作为重点月份对2016年PM_(2.5)浓度升高影响最大,在重点月份中,佳纺、环保局、发电厂、四丰4个点位PM_(2.5)月均值浓度升高较为明显。
Based on the PM_(2.5) concentration data of five air quality automatic monitoring sites in J city from 2015 to 2016,the reasons for PM_(2.5) concentration increase in J city in 2016 were analyzed.The results showed that March,May,June,November and December as the key months contributed the most of the increase of PM_(2.5) concentration in 2016.In the key months,the PM_(2.5) monthly mean concentration of Jiafang,Huanbaoju,Fadianchang and Sifeng sites increased obviously.
