Exploring the Direction of Post-pandemic Urban Development from the Land Development Perspective Using Complex Network Analysis

In order to satisfy the development needs of cities and conform to development trends, urban planners typically take into account factors such as urban function type and functional density. The purpose of this study is to construct a complex network model of urban functions and to determine the future direction of urban development. Before constructing the model, the researchers used tools such as crawlers to collect POI data within the city and classify them to determine the categories of city functions and the associated quantities. Next, urban function data were analysed and calculated to ascertain the dominant functions of each administrative district after the epidemic. In addition, the conditional probability formula was utilised to examine the interdependence between the city's functions. Finally, an urban function network model was created to investigate Wuhan, Hubei Province, as a case. The findings revealed that the current urban function layout of Wuhan city is dominated by living services, with transportation facility services, catering, and retail services as auxiliary functions, and that these functions are interconnected. The study contributed to the harmonious and coordinated development of Wuhan by providing a theoretical foundation for its development direction.
