Abstract: The living conditions of urban space are in a heterogeneous state with the experience of traditional historical gardens, and this is embodied in the physical boundary between them. In this paper, I have taken the Duxiu Hill of Ningbo Zhongshan Park and the Goushan Woodshed of Hangzhou as the objects of research. On the basis of sorting out the historical data on the evolution of the two gardens from private space to public space, I reflect on the spatial potential and value of the garden boundary, with the aid of notion on the “heterogeneity” in western cultural studies, namely how the relationships between historical memory and presence experience promote the reading of traditional gardens and the release of the expansion of spatial meaning.
