Cultural geography meets architectural typology: a mixed-methods study of traditional Bayu dwellings in Southwestern China

Traditional Bayu dwellings in China’s mountainous regions embody a rich yet underexplored architectural heritage, characterized by unique cultural and regional attributes. This study addresses the gap by investigating the architectural typologies, spatial distribution, and cultural influences of these dwellings. Employing a mixed-methods approach within the framework of cultural geography, the research integrates qualitative and quantitative methodologies. Data collection was conducted in three phases: (1) field surveys and documentation of 67 heritage-listed dwellings and 164 traditional villages; (2) collection of geographic data using GIS tools, including Digital Elevation Model (DEM) analysis; and (3) comprehensive literature review of historical and cultural records. Data analysis utilized statistical methods, including second-order cluster analysis, and spatial analysis with ArcGIS. The findings identify four primary dwelling types and delineate four architectural cultural zones shaped by geographical segregation, economic exchanges, and ethnic interactions. This study contributes to a broader understanding of the architectural culture and regional characteristics of the Bayu region, offering valuable insights for cultural heritage preservation and informing sustainable development strategies.
