Abstract: In the context of the protection and space construction of ancient tomb sites, the research paths of the urban public space and public building landscape were explored, and a reasonable protection model for ancient tomb sites was established. The park landscape was constructed based on smart city concepts and applied by the guidance systems of open space, photovoltaic power generation systems, LED night lighting, and three-dimensional greening. In concept, the protection design of ancient tomb site and landscape reconstruction centered on the unique value of the ancient tomb and combined with the current situation of the site and the technology means a design path was established. including site protection, landscape regeneration and space construction. In practice, the protection of the ancient tomb site should meet the requirements of urban ecologicalization and improve the utilization of space. Based on modem protection methods and the systemization and diversification of "joint intervention", a multi-level design system for site protection based on the unique culture value of the area was constructed.
