Quantitative Analysis of Spatial Distribution Characteristics of Traditional Villages in Hunan Province

Abstract

This study takes 658 traditional villages in Hunan province as the research object. Relying on ArcGIS geographic information system, the traditional villages in Hunan province were abstracted into point sets with attribute information. By means of average nearest neighbor distance analysis, kernel density analysis and intercity distribution comparison, the basic geographical characteristics of traditional villages in Hunan province were summarized, that is, significant agglomeration distribution, three agglomeration areas and uneven intercity distribution. Multiple types of natural geographical factors were superimposed, such as elevation, slope aspect, slope, river, water systems, annual precipitation and annual average temperature, so as to analyze the impact of elevation topography, river system and climate conditions on village site selection. With the help of geographic detector tool, the correlation between elevation, slope, water system, annual average temperature, annual precipitation and village distribution was quantitatively analyzed. Through the analysis of correlation degree, interaction and single factor characteristics, it is concluded that natural geographical factors are related to village distribution and multiple factors interact with each other. Based on the quantitative analysis of interactions between traditional villages and the natural environment, the distribution characteristics of traditional villages have been summarized, providing reference for the subsequent systematic research and protection of traditional villages.
