摘要
本文通过对北京地区的气候环境特点分析,并结合雾霾天气大气颗粒物形貌和成分的分析,结果发现:北京地区冬季雾霾天气出现天数和AQI指标明显高于夏季,北京秋冬季节频发的雾霾天气时会出现反常的高湿度天气,而且PM2.5颗粒物浓度明显高于PM10颗粒物浓度。严重雾霾天气的PM2.5颗粒物来源主要是硫氧化物和氮氧化物催化氧化形成盐所造成的。
In this paper,the characteristics of climate and environment in Beijing are analyzed,and the morphology and composition of atmospheric particulate matter in fog and haze weather are tested.The results showed that the number of days and AQI of fog and haze in Beijing area were significantly higher than that in summer.The abnormal high humidity weather will occur in the frequent fog and haze weather in autumn and winter in Beijing,and the PM2.5 particulate matter concentration is obvious.The concentration of PM2.5 particles is obviously higher than that of PM 10 particles.PM2.5 particulate matter in severe fog and haze weather is mainly caused by the catalytic oxidation of sulfur oxides and nitrogen oxides to form salts.
