“十三五”期间滨州市城市空气质量状况分析

Analysis of Urban Air Quality in Binzhou During the 13th Five Year Plan

基于“十三五”期间滨州市国控空气自动监测站自动监测数据,分析了滨州市城市空气质量状况。结果表明:“十三五”期间,滨州市空气质量总体好于“十二五”水平,PM_(10)、PM_(2.5)、SO_(2)、CO-95per呈逐年下降趋势,NO_(2)浓度基本稳定,未见明显改善;O_(3)-8h-90per出现上升趋势。滨州市PM_(2.5)、O_(3)、PM_(10)在超标天数中的占比较大,PM_(2.5)和PM_(10)的影响逐年下降,O_(3)对超标天数的影响越来越大。影响滨州市空气质量的主要污染物仍是PM_(2.5)、PM_(10),NO_(2)和O_(3)的占比影响逐年增高,SO_(2)减排效果显著。需进一步分析大气污染成因,进行综合性治理,提升大气环境质量。

Based on the automatic monitoring data of Binzhou state-controlled air automatic monitoring station during the 13th Five Year Plan period,the urban air quality of Binzhou City is analyzed.The results show that during the 13th Five Year Plan period,the air quality of Binzhou is generally better than that of the 12th Five Year Plan,PM_(10),PM_(2.5),SO_(2) and CO-95per showed a downward trend year by year,and the concentration of NO_(2) was basically stable without significant improvement;O_(3)-8h-90per shows an upward trend.Binzhou PM_(2.5),O_(3) and PM_(10) account for a large proportion of the days exceeding the standard,the impact of PM_(2.5) and PM_(10) decreased year by year,and O_(3) had an increasing impact on the days exceeding the standard.The main pollutant affecting the air quality of Binzhou City are still PM_(2.5) and PM_(10),NO_(2) and O_(3) increases year by year,and the SO_(2) emission reduction effect is remarkable.It is necessary to further analyze the causes of air pollution and carry out comprehensive treatment to improve the quality of atmospheric environment.
