胡焕庸线以东O3时空格局演变及其影响因素
Evolution of O3 spatial and temporal patterns in the east of the Hu Huanyong Line and its influencing fac-tors
摘要
Abstract
We examined the spatial-temporal evolution of O3 across 237 cities in the east of the Hu Huanyong Line.The socio-economic data,air pollutant(PM2.5,SO2,NO2)and O3 concentration data during the period of 2015-2020 were analyzed using the spatial autocorrelation method.The spillover effects of influencing factors were exa-mined by employing the spatial Durbin model.The results showed that:(1)O3 pollution demonstrated an"M-shaped"fluctuation tendency.The spatial distribution of O3 presented positive associations and characteristics of significant spatial agglomeration.High-value areas of O3 dominated in the Beijing-Tianjin-Hebei,Central Plains,and Shandong Peninsula.(2)The direct effect of the influencing factors was ranked as follows:per capita GDP＞PM2.5 concentration＞proportion of the tertiary industry＞proportion of the secondary industry＞SO2 concentration＞NO2 concentration.There was no significant direct effect of industrial SO2 emissions and highway freight traffic on O3.The intensities of the indirect driving factors'effect were as follows:per capita GDP＞proportion of the tertiary industry＞proportion of the secondary industry＞PM2.5 concentration.The PM2.5 concentration,the proportion of the secondary,and the tertiary industry exerted positive impacts on O3,while per capita GDP was the opposite.The effects of SO2 concentration,NO2 concentration,highway freight traffic,and industrial SO2 emissions on O3 were not significant.This study reveals the complexity of regional O3 pollution,and emphasizes the importance of regional joint prevention and control of atmospheric O3 pollution from the perspective of social and economic linkages,provi-ding a reference for inter-regional collaborative pollution control.关键词
