Research on urban system structure measurement supported by mobile signaling data:from the perspective of flow space
The urban system structure is the spatial presentation of the relationship between urban coordination and restriction.In this study,based on the"three structures"of the urban system,using mobile phone signaling data,a multi-scale urban system structure measurement framework is constructed from the perspective of flow space,and the urban hierarchical scale structure and regional spatial structure are integrated.In the process of measurement,the measurement model of urban hierarchical scale is improved by coupling connection flow and connection flow.At the same time,the urban regional spatial structure is measured from three aspects:urban distribution,connection and combination state.Finally,the measurement is conducted on townships in Ningbo City,the results show that the city presents a spatial pattern of"One main-core,Four sub-core,Five axes and Four districts".Accordingly,the implementation of General Urban Planning of Ningbo(2004-2020)is evaluated,the feasibility and scientificity of the framework are verified,and the suggestions for optimizing the urban spatial pattern are put forward.
