摘要
以大气污染防治行动计划实施以来京津冀区域环境空气质量数据为研究基础,以京津冀区域各主要城市环境空气质量改善效果为研究对象,综合运用反距离权重插值数学方法,对京津冀区域2014-2017年颗粒物污染演变特征进行模拟分析,系统总结分析4年来颗粒物污染变化情况,并从PM10与PM2.5浓度的比值关系着手,剖析时间、空间角度京津冀区域大气颗粒物污染特征演变,为未来京津冀区域环境空气质量持续改善的协同管理和精细化控制提供参考依据。
Based on the research on ambient air quality data of the Beijing-Tianjin-Hebei region since the implementation of the Air Pollution Prevention and Control Action Plan,taking the improvement effect of ambient air quality in major cities in the Beijing-Tianjin-Hebei region as the research object,the evolution characteristics of particulate matter pollution in Beijing-Tianjin-Hebei region from 2014 to 2017 are simulated and analyzed by the inverse distance weight interpolation.The changes in particulate matter pollution in the past 4 years are summarized and analyzed.Starting from the ratio of the concentration of PM10 to PM2.5,the evolution of atmospheric particulate matter pollution in the Beijing-Tianjin-Hebei region from time to space is analyzed to provide reference for coordinated management and refined control of the continuous improvement of ambient air quality in the Beijing-Tianjin-Hebei region.
