Traditional settlements are vital carriers of Chinese agricultural civilization yet face mounting challenges in protection and inheritance amid rapid urbanization. Taking ancient Huizhou as a case study, this research analyzes the spatial distribution patterns of cross-provincial traditional settlements and constructs a multi-level heritage corridor network through circuit theory modeling and space syntax analysis. The study reveals a “small aggregation, large dispersion” spatial structure shaped by natural geography and socio-cultural dynamics. Simulation of multi-path cultural flows and network analysis show that high betweenness corridors concentrate along the northeast–southwest axis, promoting efficient cultural circulation, while low betweenness areas highlight gaps in direct connectivity. Closeness analysis identifies She County as the cultural core with a single-center radial structure, though internal fragmentation persists. Based on these findings, the study proposes a “three-core-driven, two-axis linkage, multi-source synergy” protection strategy to strengthens the spatial integrity and resilience of the heritage network. This research not only provides a systematic framework for the holistic conservation of Huizhou settlement heritage but also offers methodological references for the protection of traditional settlements in broader regions.

This study focuses on constructing a heritage corridor for traditional villages in the Taihu Lake region, aiming to promote the cultural heritage preservation and sustainable development of these villages through innovative pathway design. Based on the spatial distribution characteristics of traditional villages across five cities surrounding Taihu Lake (Suzhou, Wuxi, Changzhou, Huzhou, and Jiaxing) and the existing transportation network, this research integrates the Circuit Effective Conductance (CEC) theory with ArcGIS spatial analysis methods to optimize the pathways of the heritage corridor. The results show that the expected nearest neighbor distance of 307 traditional villages in the Taihu Lake region is 5245.61 m, with the actual nearest neighbor distance being 3385.60 m, a z-score of −11.85, and a nearest neighbor index of 0.645786, indicating that traditional villages in this region exhibit clustered distribution. Combined with kernel density results, a “dual-core–four zones–multiple scatter points” spatial structure of traditional villages in the Taihu Lake region is revealed, with Dongshan Island and Wujiang District serving as the primary and secondary cultural cores, respectively. By establishing a “dual-ring heritage corridor” spatial network, a stable pathway for village heritage preservation and cultural transmission has been formed, consisting of 137 heritage corridors. Meanwhile, the CEC model demonstrates high adaptability in generating circular heritage corridors, particularly in creating closed-loop structures around the lake, thereby enhancing the spatial connectivity of the corridors and facilitating the effective flow of cultural resources. Through the strategic design of outer and inner ring corridors, this study successfully links traditional villages in the Taihu Lake region and develops optimal travel routes. The study provides practical solutions for the protection, revitalization, and integration of cultural tourism in the region and offers a new perspective for constructing heritage corridors in lakefront geographies in China.

As the cradle of Jiangnan culture, Suzhou is home to a dense concentration of historical architectural heritage that is currently facing existential threats from rapid urbanization. This study aims to develop a spatial heritage corridor network for conservation and sustainable utilization. Using kernel density estimation, this study identifies 15 kernel density groups, along with the Analytic Hierarchy Process (AHP), to pinpoint clusters of historical architectural heritage and assess the involved resistance factors. Current Effective Conductance (CEC) theory is further applied to model spatial flow relationships among heritage nodes, leading to the delineation of 27 heritage corridors and revealing a spatial structure characterized by one primary core, one secondary core, and multiple peripheral zones. Based on 15 source points, six cultural relics-themed routes are proposed—three land-based and three waterfront routes—connecting historical sites, towns, and ecological areas. The study further recommends a resource management strategy centered on departmental collaboration, digital integration, and community co-governance. By integrating historical architectural types, settlement forms, and ecological patterns, the research builds a multi-scale narrative and experience system that addresses fragmentation while improving coordination and sustainability. This framework delivers practical advice on heritage conservation and cultural tourism development in Suzhou and the broader Jiangnan region.

This study focuses on modern residential buildings located in the central area of Suzhou. Based on a systematic review of their historical evolution and an in-depth assessment of their current preservation and utilization status, the research identifies the common issues and key characteristics of these urban dwellings. It further categorizes both tangible and intangible cultural heritage resources associated with the residential environment. Twelve representative residential buildings, each preservation challenges, are selected for detailed analysis. Guided by principles of integrated urban renewal, the study proposes targeted regeneration strategies emphasizing the synergy between historical legacy and contemporary culture, the coexistence of productive and residential functions, the spatial integration of old and new structures, and the social inclusion of local and migrant populations. These strategies incorporate technical approaches such as structural reinforcement, adaptive reuse, spatial reconfiguration, and community-oriented design, aiming to promote the sustainable development and culturally sensitive revitalization of Suzhou’s modern residential heritage.
