摘　　要：城市公共交通服务空间公平性是评价城市交通高质量发展、可持续性发展潜力的重要指标。该文基于全局与精细格网相结合的视角,运用空间公平(SE)指数和区位熵评估了武汉市主城区公共交通资源配置的空间公平性,进而采用Pearson相关系数和多尺度地理加权回归(MGWR)模型揭示了建成环境因子对空间公平性的影响程度。结果表明:(1)武汉市主城区的三环线内呈现出6个公共交通供给高密度集聚中心和1个集聚带,交通资源供给强度具有显著的空间异质性;(2)江汉区的公共交通空间公平性最高,青山区最差,整体呈现江南优于江北、城乡结合部外优于城乡结合部内的特点,其中53%的分析单元低于研究区平均水平;(3)常规公交邻近度、居住密度、主要道路密度和道路交叉口密度对公共交通空间公平性具有显著影响。研究结果有助于提升城市公共资源配置效率,可为实现城市交通可持续、高质量发展提供辅助决策支持。The spatial equity of urban public transportation services is an important indicator for evaluating the potential of high-quality and sustainable development of urban transportation.Based on a combined global and fine-grained grid perspective and taking the main urban area of Wuhan City as an example,this paper studied the spatial equity of public transportation resource allocation and its influencing mechanism.The spatial equity(SE)index and location entropy were used to evaluate the spatial equity of public transportation resource allocation.The Pearson correlation coefficient and the multiscale geographically weighted regression(MGWR)model were then used to reveal the degree of influence of built environment factors on spatial equity.The findings are as follows.①Within the third ring road of the main urban area in Wuhan,there exist six high-density centers of public transportation supply and one supply agglomeration belt,and the supply intensity of transportation resources has significant spatial heterogeneity.②The spatial equity of public transportation in Jianghan District is the highest,while that in Qingshan District is the lowest.Overall,the southern part of Wuhan is better than the northern part,and the SE in the urban-rural fringe is higher than that outside the urban-rural fringe,with 53% of analysis units below the average level of the study area.③Public transportation adjacency,residential density,major road density,and road intersection density have significant impacts on the spatial equity of public transportation.The results of this study can help improve the efficiency of urban public resource allocation and provide decision-making support for achieving sustainable and high-quality development of urban transportation.
