以长江中游城市群为例,引入景观扩张指数来刻画城市形态演变过程,补充其内在机制分析,构建一套基于空间形态与社会经济因素结合的指标体系,以此分析城市空间与碳排放之间的关系.结果表明,2005—2020年间,长江中游城市群碳排放总量不断上升,但上升速度有所减缓;城市形态演变过程对碳排放增速存在异质化影响,外向型的城市形态演变会导致更低的碳排放增长速率,内向型的城市形态演变会导致碳排放增速提升;城市形态在不同功能和经济水平中的城市对碳排放存在差异化的影响;城市中常住人口数和城市总面积与碳排放之间关系最为密切.研究主要从动态的角度入手,分析精细化尺度下城市形态变化对碳排放的影响机制,研究发现组团式的城市形态更有利于助力低碳导向和气候响应的城市发展.
Research on the Impact of Urban Morphological Evolution Processes on Carbon Emissions from a Dynamic Perspective
Taking the city cluster in the middle reaches of the Yangtze River as an example,Thtis study,focusing on the tri-angle of central China,introduces the Landscape Expansion Index (LEI) to depict the process of urban morphological evo-lution,complementing complements the analysis of its inter-nal mechanisms. Furthermore,it constructs a comprehensive index system,based on integrating spatial morphology and so-cio-economic factors,is constructed to analyze the relation-ship between urban spatial characteristics and carbon emis-sions. The findings reveal that between 2005 and 2020,the total carbon emissions in the Triangle of Central China contin-ued to rise,albeit at a decelerated pace. The morphological evolution of cities exhibits heterogeneous impacts on carbon emission growth rates. Outward-oriented urban morphologi-cal evolution is associated with a lower increase in carbon emissions,while inward-oriented evolution leads to elevated carbon emission growth rates. Moreover,diverse impacts on carbon emissions are observed across cities with different func-tions and economic levels. Notably,the resident population and total urban area demonstrate the most pronounced correla-tions with carbon emissions. Taking a dynamic perspective,this research focuses on analysis analyzing the mechanisms un-derlying the influence of fine-scale urban morphological chang-es on carbon emissions from a dynamic perspective. The study underscores that reveals that cluster-oriented urban mor-phologies are more conducive to fostering low-carbon orienta-tion and climate-responsive urban development. These find-ings provide valuable insights for urban planners and policy-makers aiming to establish sustainable urban frameworks aligned with carbon reduction objectives.
