摘要
臭氧的有效污染防治已成为河源市持续提升环境空气质量的关键。综合运用Dagum基尼系数、OLS回归模型方法,分析了2019-2023年河源市环境空气臭氧评价浓度的时空分布及社会经济影响因素。结果表明:河源市环境空气臭氧评价浓度整体呈现“南高北低”的特点:南部区域(源城区、东源县)浓度水平较高,东部区域(龙川县、紫金县)浓度水平居中,北部区域(和平县、连平县)浓度水平较低;河源市臭氧评价浓度空间分布差异性的主要贡献来源是区域之间,区域内部的贡献来源则较少;对河源市环境空气臭氧评价浓度(Ozone)影响的显著性因素从大到小依次为:单位GDP的综合能源消费量(EC)、客运量(PT)、农林牧渔业总产值(Agri)、人口密度(PD)、工业总产值(Ind);其中EC、PT、Agri、PD对Ozone产生显著正向影响关系,可通过优化能源结构、推广新能源汽车、控制BVOC排放植被类型、规范农业废弃物的处理与资源化利用、控制厨房油烟、治理散煤燃烧等措施来降低臭氧的生成;Ind则对Ozone产生显著负向影响关系,这与河源市近年来持续推进绿美河源生态建设、走绿色崛起之路、推动传统产业转型升级等战略密切相关。
Effective prevention and control of ozone pollution has become crucial for Heyuan in China to achieve continuous improvement in ambient air quality.Using the Dagum Gini coefficient and OLS regression model,this study analyzes the spatiotemporal distribution and socioeconomic influencing factors of ambient ozone concentration in Heyuan from 2019 to 2023.The findings reveal that the ozone concentration in Heyuan exhibits a distinct"high in the south,low in the north"spatial pattern:higher levels are observed in the southern regions including Yuancheng and Dongyuan,moderate levels in the eastern regions including Longchuan and Zijin,and lower levels in the northern regions including Heping and Lianping.The spatial disparity in ozone concentration is primarily attributed to inter-regional differences,with minimal contributions from intra-regional variations.Key socioeconomic factors influencing ozone concentration(Ozone)are ranked in descending order of significance:energy consumption per unit GDP(EC),passenger traffic(PT),gross output value of agriculture,forestry,animal husbandry,and fishery(Agri),population density(PD),and industrial gross output value(Ind).EC,PT,Agri,and PD exhibit significant positive correlations with Ozone,suggesting that measures such as optimizing energy structure,promoting new energy vehicles,controlling BVOC-emitting vegetation types,regulating agricultural waste treatment and resource utilization,managing kitchen fumes,and reducing scattered coal combustion could effectively mitigate the formation of ozone.Conversely,Ind shows a significant negative correlation with Ozone,which is closely linked to Heyuan's recent strategies in the construction of the“green and beautiful ecological project”,pursuing green economic growth,and facilitating the transition and upgrading of traditional industries.
