Spatial Characteristics of Employment and Residence Distribution and Commuting Flow in Mountain Cluster Cities Based on Mobile Phone Signaling Data
To clear the spatial distribution characteristics of occupational and residential spaces and commuting flow in mountainous cluster cities,Guiyang city was selected as a case study.Based on mobile signaling data,three indicators,namely spatial dislocation index,occupational and residential deviation degree,and occupational and residential separation rate,are used to analyze the spatial relationship of urban occupational and residential spaces.And the spatial distribution characteristics of urban commuting flow are analyzed based on the social network analysis.The results indicate the following:① The spatial distribution of population and job positions in Guiyang city is basically consistent,with some spatial overlaps.②The proportion of vocational and residential areas in each county of Guiyang city is relatively high,indicating a relatively coordinated development of vocational and residential spaces.The degree of deviation from vocational and residential areas is not significant,and the vocational and residential functions are basically balanced.③The commuting space in Guiyang city generally presents a spatial pattern of"strong in the south and weak in the north".The commuting structure presents a spatial pattern with the main commuting circle centered around the old city of Guiyang and the sub-commuting circle centered around Guanshanhu District.
