This paper analyzes 4 153 traditional villages in China, and uses GIS and other spatial analysis methods to deeply analyze the distribution characteristics of traditional villages and their formation mechanisms. The research finds that: (1) The distribution of traditional villages in China is generally condensed, mainly in the eastern coastal and southwestern regions, but the causes of the two are significantly different. (2) With the change of historical periods, the spatial agglomeration form of traditional villages has changed from "single core, multiple cores" to "multiple cores, single core". The number of traditional villages in the eastern agricultural and cultural area is significantly higher than that in the western nomadic cultural area. The distribution of traditional villages in the southwestern minority agricultural and cultural sub-region is the most concentrated. The distribution of ethnic minority traditional villages is in the middle of the southwest region, and the Han traditional villages are distributed in the south of the middle reaches of the Yangtze River. (3) The formation of the distribution pattern of traditional villages is the result of the comprehensive effect of many factors. Topography, climate, precipitation, and river waters are the basic factors that determine the formation and continuation of traditional villages. Agricultural production methods and historical population migration affect the agglomeration and development of traditional villages. The key factors of the sustainable development of traditional villages are the total number of existing traditional villages and the protection of local government policies. [ABSTRACT FROM AUTHOR]
