Differential Analysis of the Impact of Spatial Morphology on Carbon Performance in the High-speed Railway New City's Catchment Area——A case study of Beijing-Shanghai High-Speed Railway Line
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.
