摘要
本文通过对AQI与大气污染物进行时空分布分析、相关系数分析,研究了京津冀地区近八年来的大气污染物数值变化,空气质量变化趋势等,得出以下结论:(1)从空间分布上看,京津冀地区的中南位置是重污染地区;京津冀地区北部地区浓度较整体低.北部地区的AQI相较京津冀地区最小,中部地区的AQI均值居中,南部地区的AQI均值最大;(2)从季节分布上看,AQI、NO2、CO、SO2 等污染物的最大值均出现在冬季,最小值出现在夏季;相反,O3 的最大值出现在夏季,最小值出现在冬季.相较于 2014 年左右,空气质量已经有了非常明显的提高.
Abstract
Through the temporal and spatial distribution analysis method of AQI,as well as the Pearson and Spearman correlation coefficient methods,this paper studied the numerical changes of air pollutants and air quality trends in the Beijing-Tianjin-Hebei region over the past eight years,the following conclusions were drawn:(1)from the perspective of spatial distribution,the southeast region of the Beijing-Tianjin-Hebei region is a heavily polluted area,while the concentration in the northern region is lower than the overall level.The AQI in the Northern region is the lowest compared to the Beijing-Tianjin-Hebei region,the average AQI in the Central region is intermediate,and the average AQI in the Southern region is the highest;(2)from the perspective of seasonal distribution,the maximum values of pollutants such as AQI,NO2,CO,and SO2 all appear in winter,and the minimum values appear in summer;conversely,the maximum value of O3 appears in summer,and the minimum value appears in winter.Compared to around 2014,there has been a very significant improvement in air quality.
