Abstract: Aiming at the prevalent issues of information silos and the lack of fine-grained management in current urban governance, this research integrates “BIM＋GIS” technologies to construct an intelligent urban design management platform, with the objective of enhancing urban spatial quality and management efficiency. Based on an analysis of the professional, staged, and hierarchical management requirements of urban design, the study proposes a platform construction strategy centered on the establishment of a knowledge system and the formulation of control standards. A four-tier technical framework is designed, consisting of the foundation, data, application, and presentation layers. By establishing a structured knowledge system that covers four critical stages:scheme review, control standards, design conditions, and parcel schemes, the platform achieves precise regulation of five core elements: land layout, building morphology, transportation planning, environmental quality, and open space. Furthermore, it integrates core functional modules such as visual spatial modeling, information sharing and query, and auxiliary review. The findings demonstrate that the “BIM＋GIS” based urban design management platform offers significant advantages, including high data compatibility and robust spatial analysis capabilities. It enables data sharing throughout the full lifecycle of digital cities, providing a systematic support tool for promoting technological innovation in urban design and scientific governmental decision-making.
