城市边缘区轨道交通市郊线的建设, 加速了城市人口空间分布格局的变化。本文从市域、边缘区以及市郊线沿线区域多尺度视角, 运用人口密度模型、空间自相关分析、人口重心模型、人口分布结构指数及偏移份额模型, 对人口规模和人口密度的空间分布特征进行分析。主要结论显示: 轨道交通带动了人口在单核心、圈层递减的基础上向边缘区的逐步转移, 边缘区的人口分布聚类性更加明显; 市郊线沿线区域人口分布更加均衡和分散; 对沿线人口的增速与沿线开发的成熟度及用地类型相关, 可大致分为三类: 全线路区段沿线人口增速均高于区域平均值, 核心区区段高于平均值、边缘区区段低于平均值, 以及全部区段人口增速低于平均值。

The construction of suburban lines of rail transit in urban fringe areas has accelerated the change in the spatial distribution pattern of population in megacities. In this paper, the population density model, spatial autocorrelation analysis, population center of gravity model, population distribution structure exponential offset share model are used to analyze the spatial distribution characteristics of population size and population density from a multi-scale perspective of the city, marginal area and suburban area. analysis. The main conclusions show that: Rail transit has led to the gradual transfer of population to the marginal area on the basis of single core and diminishing circle, and the clustering of population distribution in the marginal area is more obvious. The population distribution along the suburban line is more balanced and scattered. The growth rate of the population along the line is related to the maturity of the development along the line and the type of land use. It can be roughly divided into three categories: the growth rate of the population along the line is higher than the regional average, the core zone is high, and the margin zone is below the average Value, and the population growth rate of all sectors is lower than the average.
