In Guangzhou city, there are a large number of traditional arcade buildings, which are often constructed side by side and in different styles, resulting in the formation of distinctive arcade streets. There are a number of Guangzhou's excellent modern-day arcade buildings on the Long Bund in Guangzhou, but in recent years, the Long Bund has seen a lack of dialog between new buildings and traditional arcade buildings and a decline in traditional arcade building culture in urban development, which has led to the gradual disappearance of the historical characteristics of the arcade street on the Long Bund. The typomorphology method used in this thesis, however, analyzes the morphological evolution law of urban elements from the perspective of the evolution of urban elements over time, summarizes the morphological characteristics of urban elements, and formulates corresponding morphological design guidelines.
