The article takes Canglang Pavilion in Suzhou gardens as the research object.By consulting ancient books and county annals and applying the space syntax theory,it deeply analyzes its internal structure.The Depth map is used to establish an accurate data model to study in detail the spatial layout sequence of the corridors in the garden.It reveals the subtle connection between the garden sequence and spatial parameters and summarizes the sequence pattern of corridor space in Suzhou gardens.Through quantitative analysis of each corridor space in Canglang Pavilion,it is found that its spatial sequence is rhythmic and changes in an orderly manner.The quantitative results show that this spatial sequence can be summarized as a progressive process of"start-development-consolidation-resurgence-re-consolidation-end".
