Spatial distribution and influencing factors of Chinese traditional villages based on geographic grid
This article takes six batches of 8 171 Chinese traditional villages as the research object,and uses spatial analysis method to explore the spatial distribution characteristics and influencing factors of traditional villages based on geographic grid.The main conclusions were as follows.Firstly,the spatial distribution pat-tern of traditional villages is characterized by a significant inter provincial boundary phenomenon of concen-trated traditional villages,with three major agglomeration areas.The border between Hebei,Shandong and Henan province,the border between Anhui,Zhejiang and Jiangxi province,and the border between Guizhou,Guangxi and Hunan province.Secondly,the spatial autocorrelation of traditional village spatial distribution is obvious,with"high and high""low and high",and"low and low"spatial clustering.The mountainous and hilly areas south of the Yangtze River are the dense areas of traditional village distribution in China,while the northeast and northwest border areas are the sparse areas of traditional village distribution.Thirdly,the impact of transportation and economic factors on the spatial distribution of traditional villages is not significant.The factors of terrain,temperature,ecology,and population have a positive impact on the spatial distribution of tra-ditional villages,while precipitation factors have a small negative impact on the spatial distribution of tradition-al villages.The impact of population,town,and ecology factors on the spatial distribution of traditional vil-lages has strong spatial heterogeneity.The research results have deepened two important understandings about the spatial distribution of traditional villages.One important understanding is that the phenomenon of inter pro-vincial boundaries in the dense distribution of traditional villages is significant.These regions have similar geo-graphical environmental characteristics,mainly consisting of mountainous and hilly landforms,with the envir-onmental characteristics of"three lows and one excess"(low annual temperature,low road density,low eco-nomic development level,and high annual precipitation),which fully indicates that the natural geographical en-vironment has a very important impact on the formation and protection of traditional villages.Another import-ant understanding is that the factors that affect the spatial distribution of traditional villages have spatial hetero-geneity.It can be seen that the factors with strong heterogeneity are mostly socio-economic factors.This con-clusion provides useful insights for subsequent research on the spatial distribution and influencing factors of traditional villages.Compared with existing research literature,the contribution of this article lies in achieving the cross fusion of traditional village spatial location with multi-source data such as natural geographical factors and socio-economic factors,further verifying the effectiveness and scientificity of spatial regression models in analyzing the influencing factors of point vector elements,and enriching the technical methods for studying the spatial distribution and influencing factors of point vector elements.
