典型事件对重点城市空气质量的影响

Influence of Typical Events on Air Quality in Key Cities

分析了我国重点污染城市空气质量的时空分布特征,通过研究亚太经济合作组织(APEC)会议前后以及2011年、2012年和2014年除夕、初一两天空气质量情况,探讨了会议和节日期间环保政策对全国整体空气质量的影响。结果表明:春节期间燃放烟花爆竹虽然持续时间短但对空气质量造成了严重的影响;亚太经济合作组织会议前后出台的一些控制空气污染的暂时性政策并不会对空气质量改善起到很好的作用。

This paper analyzes the influence of environmental policies on the overall air quality during some conferences and festivals by analyzing the spatial and temporal distribution characteristics of air quality in key polluted cities.It focuses on the comparison of air quality on New Year's Eve and the day after in2011,2012and2014and before and after the APEC meeting.Results show that setting off fireworks during the Spring Festival has a serious impact on air quality,although the time is very short;temporary policies of controlling air pollution during the APEC meeting do not have very good effect on improving air quality.
