Study on Evolution Model of Public Space in Villages Using Geographic Information System and Digitization Technology

This study proposes a public space evolution model combined with density-based spatial node algorithm based on geographic information system (GIS) technology, aiming to conduct in-depth analysis and simulation of the spatiotemporal evolution of public space in traditional villages. First, this paper uses the GIS platform to digitize the spatial data of traditional villages and constructs a multi-level spatial database, covering the geographic information, population density, transportation network and other elements of public space in the village. Then, the density-based spatial node algorithm analyzes the density changes of each spatial node to identify the important nodes of the public space and their evolution trends. The algorithm can dynamically evaluate the degree of crowding, functional layout changes and interaction with the surrounding environment of the public space. Finally, this study established an evolution model containing multidimensional data such as population flow, land use, and traffic flow, and combined it with GIS technology for simulation. By analyzing the simulation results under different scenarios, it is found that there are significant differences in the functional distribution and spatial connectivity of village public space in different time periods.
