At present, many mountain historical towns face challenges such as historical fracture, unbalanced protection and development, and so on. How to systematically understand historical information and effectively transfer historical information from the old city to the new area is the focus of widespread attention in construction planning. Firstly, combined with typical practical cases, this paper expounds on the core theoretical ideas of urban morphology and architectural typology and adjusts its methods to meet the current renewal needs of Wanling Town to determine the morphological elements and scale of the research. Furthermore, starting from the four urban form elements of the overall urban spatial pattern, street system and streets, street outline and plot, and architectural layout, this paper divides the urban form units of Wanling Town. It defines the boundary and scope of its protection and renewal. Finally, the paper puts forward the renewal strategies from four aspects: the reconstruction of natural landscape space, the improvement of the hybrid transportation system, the re-division of street outline and plot, and the texture repair and reconstruction, to make the historical information continue to flow.
