2018年沙尘天气对随州空气质量的影响分析
|
摘要
该文根据2018年随州市沙尘天气发生的情况以及随州市全年空气质量数据,分析了沙尘天气对随州市空气质量的影响。结果表明,沙尘天气对随州市PM_(10)的污染贡献较大,对PM_(2.5)的污染贡献并不显著,随州市环境空气质量首要污染为PM_(2.5),且PM_(2.5)污染集中分布在每年的1月、2月及11月和12月。因此,建议随州市在春季沙尘多发季节,做好空气质量预警预报和城区扬尘的治理,同时根据城区PM_(2.5)的源清单,在每年1月、2月及11月和12月加强污染控制,以减少城区PM_(2.5)的排放,改善空气质量。
Based on the occurrence of dust weather and the air quality data of Suizhou City in 2018,this paper analyzed the influence of dust weather on the air quality of Suizhou City.The results show that the dust weather make a greater contribution to the pollution of PM_(10)in Suizhou,but not to PM_(2.5)pollution.the chief pollutant of environmental air quality in Suizhou is PM_(2.5),and it is concentrated in January,February,November and December.Therefore,it is suggested that in the dust weather prone in spring,we should do a good job in early warning and prediction of air quality and dust control in urban areas.In addition,according to the source list of PM_(2.5)in urban areas,the pollution control should be strengthened in January,February,November and December of each year,so as to reduce PM_(2.5)emissions and improve air quality in urban areas.
