Research on the spatial characteristics of traditional villages in the Tibetan-Yi corridor of China under geospatial technology approaches

The article takes 267 traditional villages in the Tibetan-Yi Corridor region as the research object, the spatio-temporal differentiation and influencing factors of the traditional villages in the Tibetan-Yi Corridor were analysed with the help of ArcGIS software. And their relationships with the natural environment, humanities and social factors were explored, in an attempt to provide a theoretical foundation and technical support for the development and conservation of the traditional villages in the area in the future.The results show that: (1) The spatial distribution of traditional villages in the Tibetan-Yi Corridor is of agglomerative structural type, with Tibetan Autonomous Prefecture of Ganzi and Lijiang City are the two places with the highest number of traditional villages. (2) The nearest-neighbour index R value of the 267 traditional villages in the Tibetan-Yi Corridor is 0.524, indicating that the traditional villages are in a clustered state. (3) A variety of factors combine to create the spatial agglomeration characteristics of traditional villages in the Tibetan-Yi Corridor, factors such as topographical features, hydrology and socio-economics may combining to affect the distribution characteristics of traditional villages.
