摘要
通过2016年12月~2017年5月陕西省10个地级市6项常规大气污染物逐小时监测数据,分析陕西省冬春季大气污染现状和时空分布规律。结果表明:(1)冬季关中地区空气质量最差,陕南、陕北地区较好,进入春季后,关中地区空气质量有显著提高;(2)冬季延安市SO2浓度异常高于其它城市,各市冬春季大气污染以颗粒物污染为主;(3)关中城市全天颗粒物污染较重,温度变化对O3小时浓度变化影响最显著,各市O3污染高频时段集中在午后。建议关中地区应加强冬季大气颗粒型污染物浓度控制,延安市应加强对SO2污染物排放的监管。
In order to analyze the temporal and spatial distribution characteristics of SO2,NO2,PM10,PM2. 5,O3 and CO in Shaanxi,data of the six air pollutants of 10 cities from December 2016 to May 2017 were evaluated. The results showed that：（ 1） In winter,the air quality in Guanzhong area was worse than that in southern Shaanxi and northern Shaanxi area,after entering spring,the air quality has improved significantly in Guanzhong.（ 2） The concentration of SO2 in Yanan was abnormally higher than other cities in winter,and the air pollution was dominant by atmospheric particulates from in spring.（ 3） The particulate pollution throughout the day in Guanzhong City is heavy. Temperature change was the most significant influencing factor on O3 hourly concentration change,and the high pollution of O3 appeared in the afternoon. It is suggested that the concentration control of particulate pollutants should be strengthened in winter in Guanzhong,and the regulation of SO2 pollutant emission should be strengthened in Yanan.
