带状城市居民通勤及职住平衡研究——以济南市中心城区为例

Research on Ribbon Cities’Commuting Characteristics and Jobs-housing Balance:A Case Study of Jinan

以济南市中心城区为研究对象,基于居民通勤调查分析居民通勤特征,重点剖析带状形态影响下的居民通勤流动、职住密度圈层及职住平衡状况的空间差异。研究表明:东西狭长的带状城市东西向通勤居多,其通勤距离、时间更长,满意度更低;通勤流量密度呈现东西拉长的椭圆状分层结构;带状城市居民职住密度由中心区域向外围降低,依据职住密度划分三大椭圆圈层:核心区、近郊区、远郊区,离核心区越近、就业密度越高职住平衡状况越好。

Taking the downtown area of Jinan as the research object,based on the residents’commuting survey,this paper analyzes the characteristics of residents’commuting,focusing on the spatial differences of residents’commuting flow,occupation and residence density circle and occupation and residence balance under the in fluence of belt shape.The research indicates that the strip cities with long and narrow east strip and west strip are mostly commuters with longer commuting distance and time and lower satisfaction.Commuting traffic density presents an elliptical layered structure with east-west elongation.The density of residential residents in strip cities is reduced from the central area to the periphery.According to the occupational density,the three elliptical circles are divided into:core area,suburban area,and remote suburb.The closer to the core area,the higher the employment density,the better the occupation and living balance.
