摘要
针对现有碳排放相关研究中存在的研究尺度过大、非发达区域研究较少、影响因子交互作用分析不足等问题,以宜荆荆恩城市群为例,对新兴城市群碳排放的时空格局与影响因素开展研究。基于1997—2017年碳排放数据,运用碳排放强度分析、空间自相关分析以及地理探测器等工具,对宜荆荆恩城市群碳排放特征进行了探讨。结果表明:时间上,宜荆荆恩城市群碳排放量总体呈增长趋势;空间上,碳排放量和碳排放强度总体分布格局相对稳定,有一定的空间聚集特征,呈现出“北高南低、东高西低”的格局;碳排放空间分异受多种因素综合影响,其中规模以上企业数量、居民储蓄存款等因素的影响最为显著,各影响因子间的交互作用对碳排放空间分异格局具有重要的空间叠加效应。根据研究结果,提出调整能源结构、提升碳汇能力、加快产业转型、优化空间布局、倡导低碳生活等建议,可为城市群制定碳排放政策提供依据,并为类似地区相关研究提供参考。
In view of the existing problems in carbon emission related research,such as excessive research scale,few studies in non-developed regions,and insufficient interaction analysis of influencing factors.Taking Yichang-Jingzhou-Jingmen-Enshi urban agglomeration as an example,the spatial-temporal pattern and influencing factors of carbon emission in emerging urban agglomeration were studied.Based on the carbon emission data from 1997 to 2017,this study used carbon emission intensity analysis,spatial autocorrelation analysis,and geoprobes to explore the spatiotemporal evolution and influencing factors of carbon emissions.The results showed that:over time,the carbon emissions of the Yichang-Jingzhou-Jingmen-Enshi urban agglomeration had shown an overall increasing trend;spatially,the overall distribution pattern of carbon emissions and carbon emission intensity was relatively stable,with certain spatial aggregation characteristics,showing a″high in the north,low in the south″and″high in the east,low in the west″pattern;the spatial differentiation of carbon emissions was influenced by multiple factors,among which the number of large-scale enterprises and household savings deposits had the most significant impact.The interaction between various influencing factors had an important spatial superposition effect on the spatial differentiation pattern of carbon emissions.Based on the research results,suggestions are made to adjust the energy structure,enhance carbon sink capacity,accelerate industrial transformation,optimize spatial layout,and promote low-carbon living,which can provide basis for formulating carbon emission policies in urban agglomerations and provide reference for related research in similar areas.
