摘　　要：本文构建GWR(Geographically weighted regression)模型拟合建成环境变量与地铁客流的关系,并分析建成环境显著变量对地铁客流的异质性影响。采用西安市地铁1、2、3号线63个站点共5个工作日的客流数据,利用ArcGIS软件将客流数据与交通小区匹配,在传统最小二乘法的基础上构建GWR模型,考虑人均GDP、土地利用混合度、停车场密度、交叉口密度、地铁出入口密度等对交通小区地铁客流的影响,得到如下结论:GWR模型能有效刻画交通小区地铁通勤客流与建成环境变量互动关系的空间非平稳性及影响尺度,其结果优于传统最小二乘法;同时,分析发现人均GDP、土地利用混合度、交叉口密度、地铁出入口密度4个变量对交通小区地铁客流的影响显著;土地利用混合度对地铁通勤客流的吸引远远大于地铁出入口密度,且在土地利用开发程度和均衡度较低的交通小区表现更明显。This paper using the Geographically Weighted Regression model to fit the relationship between built environment variables and subway passenger flow,and analyzes the influence of significant variables on subway passenger flow.Using the passenger flow data of 63 stations of Xi'an Metro Line 1,2 and 3 for 5 working days,and ArcGIS to match the passenger flow with the traffic analysis zones.On the basis of the traditional least squares regression model,constructed the GWR model.Considering the impact of GDP per capita,land use mixing degree,parking lot density,intersection density,subway entrance and exit density,etc.on the passenger flow of subway entrances and exits.The following conclusions can be obtained:The GWR model can depict the spatial non-stationarity and influence scale of the interaction between subway commuter passenger flow and built environment variables,and its results are better than the traditional least squares method.Meanwhile,we found that four variables-GDP per capita,land use mixing degree,intersection density,and subway entrance and exit density-have significant effects on subway passenger flow.The attraction of land-use mixing degree to subway commuter traffic is much greater than the density of subway entrances and exits,and more obvious in traffic analysis zones with low degree of land use development and balance.
