Ethnic differentiation in the internal spatial configuration of vernacular dwellings in the multi-ethnic region in Xiangxi, China from the perspective of cultural diffusion

Understanding the cultural characteristics and evolution of traditional dwellings in the context of ethnic integration is of great significance for protecting the diversity of residential cultural heritage of ethnic minorities. This article compares the ethnic differences in the internal spatial configuration of vernacular dwellings in Xiangxi region, China, a typical multi-ethnic area where “line-shaped” dwellings are prevalent among the Miao, Dong, Yao, Tujia, and Han groups. This study found that the spatial sequence, ritual axis, importance of fireplace, spatial hierarchy, and privacy of bedrooms of each ethnic group's dwellings present a trend towards Han’s dwelling culture in the order of "Western Miao, Southern Dong, Northern Dong, Yao, Eastern Miao, Tujia". Based on the analysis of the lifestyles, ethnic customs, and historical development processes of ethnic minorities, this study identifies that the main reasons for the formation of the aforementioned sequence lie in the differences in the historical diffusion patterns and paths of Han culture in Xiangxi. This article analyses the ethnicity of minority residential culture in Xiangxi and its spatial configuration formation process, revealing the relationship between the spatial effect of Han cultural diffusion pattern and the spatial difference pattern of each ethnic group's vernacular dwelling space configuration, and expanding the connotation of "cultural genotypes" in multi-ethnic areas.
