以轨道生活圈建设为目标，梳理轨道站区可步行性影响因素，分别从站点本身的步行可达性、站区服务设施的步行可达性、服务设施配置水平3个方面构建地铁站区可步行性测度体系。选取北京28个轨道微中心站点为研究对象，运用ArcGIS空间分析法和步行指数法，从定量和定性2个角度，测度了站区1000m范围内的可步行性，评价了地铁站区道路网络的通达性及设施配置的均衡性和可达性，并利用热力图验证了步行指数测度结果与实际活力区域的匹配度。提出了北京轨道微中心地区可步行性现状问题及相应的对策建议

The walkability measurement research of subway station area is carried out with the goal of the construction of rail life circle. The walkability influencing factors of rail station area are sorted out, and the walkability measurement system of subway station area is constructed from three aspects: the walkability of the station itself, the walkability of the service facilities in the station area, and the configuration level of the service facilities. Taking 28 track micro centers in Beijing as research objects, this paper uses ArcGIS Spatial analysis method and pedestrian index method to carry out quantitative and qualitative analysis and measurement of the walkability within 1000m of the station area, comprehensively evaluates the road network accessibility and the facilities configuration balance and accessibility in the subway station area, and verifies the matching degree between the measurement results of pedestrian index and the actual dynamic area by thermal map analysis. The current situation of walkability in Beijing track micro center area is pointed out and corresponding countermeasures and suggestions are proposed.
