摘要
研究利用中国环境保护部(MEP)公布的在线小时数据,通过AQI及定性定量的相关分析法,研究了2017年至2020年河北省污染物PM_(2.5),PM_(10)、CO、SO_(2),NO_(2)和O_(3)-8h的时空变化规律,得到如下结论:河北省位于中国华北平原地区,污染较严重,其PM_(2.5)、PM_(10)和O_(3)浓度较高;从未达标天数来看,PM_(2.5)和O_(3)对河北省大气污染的贡献最大,其次是PM_(10);就季节变化情况来说,PM_(2.5)、PM_(10)和CO的变化规律较相近,SO_(2),NO_(2)的变化趋势较平缓,夏季。3浓度最高;冬季的主要污染物是PM2S,其污染比较严重的城市有邯郸、邢台、石家庄和保定,而污染较轻的是张家口和承德;夏季的主要污染物是0_(3),其污染较重的是张家口和保定,污染较轻的是唐山。
This study applies the pollutants PM_(2.5),PM_(10),CO,SO_(2),NO_(2) and O_(3)-8h from 2017 to 2020 by using the online hourly data released by the Ministry of environmental protection of China(MEP),through AQI and quantitative qualitative correlation analysis.The results show that Hebei Province is located in the North China Plain,with serious pollution,and its PM_(2.5),PM_(10),and O_(3) concentration are higher,especially prominent.In terms of days without reaching the standard,PM25 and O_(3) are the largest air pollution in Hebei Province,followed by PM_(10);in terms of seasonal changes,the change rules of PM_(2.5),PM_(10) and CO are similar,and the changes of SO_(2) and NO_(2) are similar.The trend is gentle,the concentration of O_(3) is the highest in summer;the main pollutants in winter are PM_(2.5),and the cities with more serious pollution are Handan,Xingtai,Shijiazhuang and Baoding,while the ones with relatively light pollution are Zhangjiakou and Chengde;the main pollutants in summer are O_(3),which are Zhangjiakou and Baoding,and Tangshan is the lighter.
