摘要
对2014—2017年影响京津冀13个地区空气质量的6项指标数据进行分析,并以保定市为例分析了各指标变化的原因及规律。结果显示:PM2.5、PM10、SO2、CO浓度年均值总体呈下降水平,NO2、O3浓度的年均值波动幅度较大,2016年相对于2015年NO2的浓度总量上升,2017年相对于2016年O3的浓度总量上升,其他年份均下降。2014—2017年6项指标的浓度的年均值存在显著性差异,总体来说:京津冀13个地区的空气质量均有明显好转。
The data of six indicators affecting air quality- from 2014 to 2017 are analyzed, in addition, this article analyzes the reasons and laws of each index change in Baeding City. The results showed： the annual mean of PM2.5 , PMl0 , SO2 , CO was decreasing ; the annual mean of NO2, 03 concentration fluctuates greatly. In 2016, the concentration of NO2 was higher than that in 2015, and the total concentration of 03 in 2017 was higher than that in 2016, and all other years declined. There was a significant difference in annual mean concentration of six indicators from 2014 to 2017. In general ： the air quality in the 13 regions of Beijing-Tianjin-Hebei region was significantly improved.
