摘要
在空气污染日益受到大众关注与石油价格剧烈波动的时期,通过使用美国驻广州、北京和上海的领事馆PM_(2.5)数据,定量研究了2014—2015年国内历次油价变动与PM_(2.5)浓度变化的关系。结果表明北上广PM_(2.5)浓度变化幅度与油价的变动方向与幅度相关性不大,大气污染与燃油价的关系不明显。PM_(2.5)浓度主要受气候和天气等季节性因素影响,一般夏季浓度最低,冬季浓度相对较高。
In the period of air pollution gaining growing public concern and oil price volatility changing, using the PM2.5 concentration data in the US Consulate General in Guangzhou, Beijing, and Shanghai in the year of 2014 and 2015, the relationship of successive changes between domestic gasoline prices and PM2.5 concentration was quanti-tatively studied. The results showed that changes of PM2.5 concentration had no significant correlation with changes of direction and magnitude of fuel price. There was no obvious relationship between air pollution and fuel prices. PM2.5 concentration is mainly affected by seasonal factors such as climate and weather. Generally, PM2.5 concentra-tion was lowest in summer and relatively high in autumn.
