Research On The Watershed Differentiation Of Traditional Villages In Yunnan Province

Yunnan Province is located in the southwest frontier area of China,with vast mountainous area,obvious three-dimensional climate,and numerous ethnic minorities.The river system is an important natural environment for the survival and development of villages,and an important carrier for the cultural exchange and integration of traditional villages.The formation and development of traditional villages are deeply influenced by the geographical environment.Watershed is the basic unit for studying natural and human geographical phenomena,and it is also the basic perspective for studying the spatial relationship of traditional villages.However,the existing village research lacks the research on the settlement system of villages in the complex geographical environment through the river basin,and lacks the comparison of the differences between the river basins.The study takes 708 traditional villages in Yunnan Province as the research object,starts from the perspective of the watershed,uses Arc GIS 10.5 as the research platform,and combines quantitative analysis methods such as SPSS to study the differentiation characteristics of traditional villages in Yunnan Province,and explore the space of traditional villages in each watershed.The influencing factors of differentiation are revealed,and the internal relationship is revealed,so as to propose traditional village protection countermeasures,and provide a research basis for the protection of traditional villages in Yunnan Province.The main results of the research are as follows:（1）The spatial distribution of traditional villages in Yunnan Province presents significant river basin differentiation characteristics: First,the distribution of traditional villages in various river basins in Yunnan Province is extremely uneven,mainly in the Lancang River Basin and the Jinsha River Basin.Secondly,there is also obvious distribution heterogeneity in each basin.The traditional villages in the Dulongjiang-Longchuan River basin are more concentrated,and the traditional villages in the Lancang River basin are more scattered.（2）The river basin differentiation characteristics of traditional villages in Yunnan are the result of the combined forces of natural geographical environment and human geographical environment at different scales.Through the correlation analysis of the influencing factors of traditional village basin differentiation in Yunnan Province,it is found that the spatial distribution of traditional villages in the Dulong River-Longchuan River basin has the most significant correlation with the Han population,the distance from the central city,the distance from the post station,and the river network density.The spatial distribution characteristics of traditional villages have the most significant correlation with road network density and river network density.The spatial distribution of traditional villages in the Lancang River Basin has a significant correlation with river network density,average annual precipitation,road network density,and distance between stations.The spatial distribution of traditional villages in the Jinsha River Basin has a significant correlation.The distribution is significantly correlated with the river network density,distance from the central city,the distance from the station,and the proportion of the Han population.The spatial distribution of traditional villages in the Yuanjiang River Basin has a significant correlation with the density of the river network,elevation,distance from the station,and population density.The spatial distribution of traditional villages in the Pearl River Basin has a significant correlation with Temperature,distance from the central city,distance from the station,and the proportion of Han population are significantly correlated.（3）Based on the perspective of the watershed,and based on the requirements of regional economic development and management,the following suggestions are put forward for the protection and development of traditional villages in each watershed:build a "culture-natural resource-village" protection and development model in the Dulong River-Longchuan River Basin,and in the Nujiang River Basin.Build a protection and development model of "nation-resource-village",and build a protection and development model of "culture-international-village" in the Lancang River Basin.In the Jinsha River Basin,a protection and development model of "style-ecology-village" has been established;in the Yuanjiang River Basin,a "resource-heritage-village" protection and development model has been established;...
