Research on Urban Functional Zone Identification and Spatial Interaction Characteristics in Lhasa Based on Ride-Hailing Trajectory Data

A new method combining ride-hailing trajectory data with Point of Interest (POI) data reveals that Lhasa's urban functional zones exhibit a 'highly composite core, relatively differentiated periphery' pattern. The study identified eight distinct functional zone types, including commercial-residential mixed and science-education-culture areas, with residential regions forming the base and the core area featuring multi-functional agglomeration. The spatial interaction network demonstrates small-world effects and a lognormal degree distribution, highlighting key hubs like Lhasa Station and the Potala Palace. Four functionally coupled communities were detected, forming a 'core leading, two wings supporting' center-subcenter spatial organization pattern. This approach offers a novel perspective for understanding plateau city structures and planning.
