Simulating spatiotemporal dynamics of urban underground space development using multi-agent system: A case study in Changzhou City, China

摘要

The development of urban underground space (UUS) serves to promote the intensive use of land resources, overcome the shortage of space resources, and achieve sustainable urban development. Since UUS development is a dynamic and complex process involving diverse stakeholders, investigating its operating mechanisms and predicting its trajectory is crucial to achieve sustainable urban development. This study used a multi-agent system modeling method to build a UUS development decision-making model for exploring the interactions between different stakeholders and their adaptive decision-making behaviors. The model allows the dynamic UUS development process to be presented spatially, considering the spatiotemporal changes in environmental, economic, and social factors. The actual status and three future scenarios of UUS development were simulated and analyzed for the Yanling business district of Changzhou City, China. The simulation results show that the model can effectively describe, interpret, and predict the dynamic spatiotemporal process of UUS development, thereby providing theoretical reference and decision-making support for UUS planning and policymaking.
