Multi-scale spatial distribution characteristics and influencing factors of Chinese vernacular culture

Promoting the overall cognition of vernacular culture is an important measure to repair the genes of cultural space and implement rural revitalization in China. In view of this, taking the directory data representing vernacular culture as the research object, the methods such as mathematical statistics, spatial analysis, geographic detector (GD) and geographic weighted regression (GWR) were comprehensively used to quantitatively explore the spatial distribution pattern and influencing factors of vernacular culture. The results show that: ① vernacular culture presents a clustering distribution pattern at the national scale, and the interprovincial distribution is unbalanced; ② The spatial distribution of culture shows a "core-edge" characteristic bounded by Hu Huanyong Line, and the core area clusters in the Yangtze River and Yellow River basins and the eastern coastal area; ③ The economic and social factors explain much more than the natural factors for the spatial differentiation of vernacular culture, and people’s subjective initiatives are the dominant force for the development of vernacular culture; ④ Complex coupling effect of various factors result in the spatial differentiation of vernacular culture, and the interaction between economic and social factors is the strongest; ⑤ The GWR model constructed by the five factors with the best effects could explain 34.9% of the spatial differentiation characteristics of vernacular, and the intensity and direction of different factors are significantly different in terms of spatial effects.
