摘要:
由于城市空气污染物具有区域扩散性,基于单个城市的空气质量研究具有较大的局限性,所以要从区域角度分析不同城市之间空气质量的内在联系。本文利用相关性分析的方法重点分析了北京地区与石家庄地区相同大气污染物(PM2.5, PM10, CO, NO2, SO2)月平均浓度之间的相关关系,发现两地的CO月平均浓度之间有较强的相关性,SO2月平均浓度之间的相关关系次之,PM2.5月平均浓度之间相关关系最弱。通过对两地区相同污染物之间月平均浓度的相关性分析,进一步阐述了北京周边地区大气污染物扩散迁移对北京地区空气质量的影响,为北京及其周边城市区域大气污染的控制和环境保护政策的制定提供有利建议。

Abstract: With the regional diffusivity of urban air pollutants, the research of air quality based on single city has great limitation, so it is necessary to analyze the internal relationships of the air quality in different cities from the regional point of view. This paper uses correlation analysis method to mainly analyze the relationships among the same atmospheric pollutants (PM2.5, PM10, CO, NO2, SO2) of their monthly average concentrations between Beijing and Shijiazhuang, which has found that the monthly average concentration of CO has a strong correlation between the two cities; the monthly average concentration of SO2 takes the second place and that of PM2.5 is the weakest. The further elaboration, according to the analysis of the monthly mean concentrations' correlations of the same pollutants between the two regions, tells the effects on the air quality in Beijing caused by the air pollutants diffused from Beijing surrounding areas, which provides favorable proposals for air pollution control and the establishment of environmental protection policy for Beijing and its surrounding areas.
