[目的] 揭示县域碳排放的时空格局演变及其驱动因素,为区域规划战略的实际应用和实现“双碳”目标提供科学依据。[方法] 基于广西壮族自治区东融发展片区2005,2010,2015,2020年碳排放数据,运用空间自相关分析测算各区域之间的碳排放时空异质性特征,并在构建指标体系的基础上,运用地理探测器计算碳排放时空演变的驱动因子。[结果] ①广西东融片区各县区碳排放量在空间上存在异质性。2005—2020年,该区碳排放量在空间上呈现“西南高,东北低”,经济发达的区县碳排放量增速快;②各区县碳排放量在总体上呈现稳步上涨的趋势。不同经济发展水平的区县间碳排放量差距逐渐拉大;③在碳排放时空分异驱动力分析方面,能源消费结构和城市经济密度的影响最强。[结论] 广西东融发展片区碳排放时空特征与人类活动密切相关,达成“双碳”目标必须以规范碳排放行为为前提。
[Objective] The spatiotemporal evolution pattern and driving factors of carbon emissions at the county level were determined in order to provide a scientific basis for the practical application of a regional planning strategy that would meet the "dual carbon" goal.[Methods] Based on carbon emission data from the Dongrong development area in the Guangxi Zhuang Autonomous Region in 2005
2010
2015
and 2020
spatial autocorrelation analysis was used to calculate the spatio-temporal heterogeneity of carbon emissions among different regions. An index system was constructed
and geographic detectors were used to calculate the driving factors of the spatio-temporal evolution of carbon emissions.[Results] ① There was spatial heterogeneity in carbon emissions among the counties and districts in the Dongrong development area of the Eastern Guangxi Zhuang Autonomous Region. From 2005 to 2020
the carbon emissions in the space were characterized as being "high in the southwest and low in the northeast"
and the carbon emissions of the economically developed districts and counties grew rapidly; ② The carbon emissions of the districts and counties showed a steady upward trend in general. The carbon emissions gap between districts and counties with different economic development levels gradually widened; ③ An analysis on the driving forces of spatial and temporal differences of carbon emissions showed that the influence of energy consumption structure and urban economic density was the strongest.[Conclusion] The spatial and temporal characteristics of carbon emissions in the Dongrong development area of the Eastern Guangxi Zhuang Autonomous Region were closely related to human activities. In order to meet the "dual carbon" goal
carbon emissions will need to be regulated.
