摘要

Set against the dual imperatives of rural revitalization and cultural heritage preservation, research on heritage-based rural tourism has widely examined spatial clustering and influencing factors, yet comparatively less attention has been paid to cross-jurisdictional fragmentation and the identification of cultural heritage corridors based on reproducible spatial rules. This study examines how heritage-based rural tourism destinations are spatially organized and what factors drive their vitality in the Yangtze River Delta, using 1,247 nationally designated traditional villages. Based on a multidimensional dataset integrating geospatial coordinates, elevation and terrain conditions, transportation infrastructure, point-of-interest (POI) information, and cultural heritage resources, we first characterize regional clustering patterns and local hotspots, then evaluate multi-factor drivers, and finally identify potential cross-regional cultural heritage corridors. Kernel density estimation reveals a pronounced “core-and-corridor” configuration, with high-intensity clusters located in the Hangjiahu Plain, the Taihu Basin, and the transition zone spanning southern Anhui and western Zhejiang. Local Indicators of Spatial Association (LISA) further confirm discrete high-activity hotspots and highlight spatial fragmentation, where administrative boundaries form isolated “cultural enclaves” in which heritage resources are insufficiently activated. Multiple linear regression and random forest analyses jointly indicate that road network density is the dominant positive determinant of tourism vitality, whereas elevation and terrain ruggedness exert significant negative influences; the contribution of socio-economic variables is more limited in the linear specification but becomes more evident in the non-linear model. To operationalize the corridor perspective, we apply the density-based spatial clustering algorithm DBSCAN to heritage-rich villages (1 km buffer) to automatically detect corridor clusters, complemented by rule-based/manual delineation for a second potential route. Two principal cultural corridors are thus identified: an empirically delineated Huizhou corridor characterized by traditional craftsmanship, ancestral architecture, and folk theatre, and a prospective water-based route integrating historic settlements and regional performing arts. By advancing a “Pattern–Endowment–Driver–Gradient–Coupling” model, this study provides an empirically grounded basis for integrated spatial governance and cross-jurisdictional corridor planning for traditional villages.
