As the most important cultural heritage in Chinese cities, the historical conservation areas with their adjacent historical features have always shown people the unique characteristics of cities. In recent years, with the progress of urbanization, historic conservation areas are generally in a conflict between conservation and development, between traditional and modern types and morphological changes. A morphological analysis method compatible with Chinese reality needs to be urgently developed. The Italian school of typo-morphology is one of the three schools of urban morphology, which is more suitable for the analysis and design of urban morphology. It can not only explain the evolution of urban morphology and building types, but especially link the past, present and future of a city through theoretical analysis and design.
