摘要: 通过分析武汉市PM2. 5与SO2、NO2、CO、O3浓度间的相关性,得到PM2. 5与SO2、NO2、CO间存在正相关性,与O3间存在负相关性,并对存在这种相关性的原因进行了解释,同时对PM2. 5 与SO2、NO2、CO 间的上尾相关系数进行了估计。估计结果表明:SO2、NO2、CO、O3浓度的急剧上升会加剧PM2. 5的产生,最后对武汉市治理PM2. 5提出了建议。

Abstract: By analyzing the correlation between PM2. 5 and SO2, NO2, CO,O3 concentration in Wuhan,it was obtained that there was a positive correlation between PM2. 5 and SO2, NO2 ,CO ,and negative correlation between PM2. 5 and O3,the writer explained the reason of these correlations. The uppertail correlation coefficients of PM2. 5 and SO2, NO2,CO were estimated. The results showed that the rapid increase of SO2,NO2 ,CO and O3 concentration had a great influence on the concentration of PM2. 5 . Finally,the writer put forward some suggestions on the treatment of PM2. 5 in Wuhan City.

Key words: Wuhan City, PM2. 5, air pollutants, Archimedean Copula function, correlation;uppertail correlation coefficient
