南京中心城区轨道交通站域用地强度分布模式研究

Research on the Distribution Pattern of Land Intensity of Rail Transit Station Areas in the Central City of Nanjing

南京作为国内首批公交都市之一,倡导发展公共交通引导城市高效建设,研究其轨道交通站域用地强度空间分布,对我国大中城市轨道交通与用地协调发展具有重要的参考价值。研究选取南京市中心城区发展较为成熟的5条市区线路98个站点,采用圈层分析与扇区分形结合对站域强度分布形态进行标准化处理,归纳出圈层、扇形、点轴、混合和无规律分布等5种强度分布模式,并分析各模式站点空间分布规律。研究发现:不同强度分布模式站点的空间分布与站点区位条件、商业中心体系规划、城市用地强度和站域用地性质密切相关。

Nanjing,as one of the first public transportation cities in China,advocates the development of public transportation to guide the efficient construction of the city.The study of the spatial distribution of land intensity of its rail transit stations has important reference value for the coordinated development of rail transit and land use in large and medium-sized cities in China.The study selected 98 stations of 5 urban lines in the central city of Nanjing,and standardized the intensity distribution pattern of station area by combining circle analysis and sector shape,and summarized 5 intensity distribution patterns,such as circle,sector,point axis,mixed and irregular distribution,and analyzed the spatial distribution pattern of stations in each pattern.It is found that the spatial distribution of stations with different intensity distribution patterns is closely related to the station location conditions,commercial center system planning,urban land intensity and station land nature.
