国庆假日济南城区大气环境质量特征及其影响因素研究

Characteristics and Influencing Factors of Atmospheric Environment Quality in Jinan City during National Holiday

运用相关性分析法、主成分分析法探究国庆假日济南城区大气环境质量特征及其影响因素。结果表明:PM2.5、PM10、CO是国庆期间的主要污染物,小时浓度的峰值出现在9时和23时,谷值出现在14时;PM2.5、PM10是首要污染物,日均浓度(除去10月6日)均超过国家二级标准,10月1日PM2.5浓度上升33.6%,PM10上升34%,10月2日和4日出现浓度"双峰",3日和6日出现浓度"双谷",6日浓度值降至国庆最低,10月7日颗粒物浓度迅速回升;节假日期间,合理安排旅游行程,有利于缓解城市环境压力,促进城市可持续发展。

The atmospheric environment quality of Jinan is analyzed with correlation analysis and principal component analysis method.Peak concentrations of dominant pollutants like PM2.5 and PM10 appeared in 9:00 and 23:00, valley values appeared in 14:00.The daily average concentrations exceeded the national secondary standard, PM2.5 rose by 33.6% and PM10 rose by 34%on October 1st.The maximum concentrations during National Holiday and the minimum concentrations on 6th.The concentrations PM2.5 and PM10 picked up rapidly on 7th.Making reasonable arrangements to avoid the peak tour can alleviate the ambient pres-sure and promote sustainable development of the city.
