摘　　要：空间碳绩效与站域空间形态特征之间关系密切。然而既有研究大多致力于探究城市整体空间对碳排放的影响机制,较少将其站域空间细分类别进行对比分析。基于三个维度构建高铁新城站域空间碳绩效测算方法,并通过二阶聚类法对其站域空间形态进行分类,对比研究高铁新城站域空间形态对碳绩效的影响。针对京沪线的研究案例表明:不同站域空间形态类型对空间碳绩效的影响因素与作用机制,存在显著差异性和相似性,其中交通通勤环境是影响空间碳绩效的全局变量且具有显著的抑制作用;站域社会环境与站域建成环境对空间碳绩效的作用强度及方向存在空间异质性。不同站域空间形态对碳绩效的差异化说明:针对站域空间碳减排的规划措施,不仅要考虑空间形态对其作用的指标因素差异,还要考虑不同站域类型对其空间效应的差异。Spatial carbon performance is closely related to the spatial morphology characteristics of the catchment area.However,most of the existing research focuses on exploring the impact mechanism of urban overall space on carbon emissions,and less on the comparative analysis of its sub-categories like the station's catchment area.Based on three dimensions,a measurement method of the spatial carbon performance of the high-speed railway new city's catchment area is constructed and the spatial morphology is classified by second-order clustering method to study the impact of the spatial morphology on the carbon performance in the high-speed railway new city's catchment area.The results of the research on the Beijing-Shanghai High-speed Railway Line show that there are significant differences and similarities in the influencing factors and mechanisms of different station spatial forms on spatial carbon performance.Among them,the traffic and commuting environment is a global variable that has a significant inhibitory effect on the spatial carbon performance.There is spatial heterogeneity in the intensity and direction of the influence of the social environment and the built environment of the station's catchment area on the spatial carbon performance.This differentiation indicates that,in terms of planning measures for carbon reduction in the station's catchment area,attention should be paid to not only the different index of the effects of spatial form,but also those of different types of the station's catchment area.
