摘要
随着社会经济的快速发展,我国大气环境越来越恶劣,雾霾现象严重。本文选取雾霾较为严重的北京、广州、上海、成都和沈阳五个代表性城市,对历年春节期间、特别是除夕夜的空气质量进行因素分析,找出燃放烟花爆竹对雾霾PM2.5和PM10影响较大的气体因素,并构建相关的回归模型,用于节日庆典燃放烟花期间的空气质量预测。通过本文分析可知,燃放烟花炮竹对PM2.5和PM10浓度的定量影响,为此建议大家在节假日期间尽量少燃放烟花爆竹,为保护生存环境做出努力。
With the rapid development of economy, the atmospheric environment in China is becoming worse and worse. Five representative cities with the serious haze pollution, Beijing, Guangzhou, Shanghai, Chengdu and Shenyang, are selected to analysis the effect of fireworks on the air quality. Especially the real-time air data of on New Year＇s Eve are analyzed based on factor analysis in order to find out how the fireworks influence the PM2.5 and PM10 concentrations. Furthermore, the relevant regression models are built to predict the air quality under the festival fireworks conditions. The results show that the effect of setting off fireworks on PM2.5 and PM10 concentration is very big. We recommend to reduce the fireworks and firecrackers during the holiday as far as possible for the sake of environment.
