Common Living in Residential Historic Districts and Methods for Unitization Identification
The spatial structure and social dynamics of common living in residential historic districts are highly complex,representing an efficient neighborhood model and a significant challenge in historic district renewal.This paper explores spatial and social perspectives,focusing on the smallest residential unit as the node.It iden-tifies various connection paths for urban,communal,and private spaces using depth and path methods,and establishes a spatial network incorporating spatial gravity.Fur-thermore,it constructs an adjacency matrix,a weighted network representing social characteristics,based on relationship strengths among acquaintances,semi-acquaintances,and strangers.Through matrix operations,the paper integrates spatial and relational networks into a"relational-spatial"network,revealing the comprehen-sive structural characteristics and unitized features of residential historic districts.It further derives a method for identifying unit-based common living and validates its effectiveness across samples with different ownership statuses.Finally,the paper dis-cusses the scientific and practical implications of the"relational-spatial"network and unitization identification method in spatial cognition,urban regeneration planning,and policymaking.
