Abstract:: Exploring the spatial distribution characteristics of rural settlements in mountainous areas can optimize the layout of rural settlements and coordinate regional development, which plays a significant role in improving the living standards of residents in mountainous areas. Taking Bazhong City as the research object, we analyzed the spatial distribution characteristics and patterns of rural settlements in Bazhong City by using the methods of standard deviation ellipse analysis, nuclear density estimation and average nearest neighbor index, and explored the impact of natural environment and socio-economic factors on rural settlements. The results show that the rural settlements in Bazhong City mainly distribute in the southwest region, the number decreases outward in a ladder shape, showing the characteristics of southwest northeast elliptical distribution, and the center is located in the northeast of Bazhou District; the settlements generally evenly distribute, and each county presents a cluster random uniform chain distribution from top to bottom, with significant regional distribution; rural settlements in Bazhong City have an obvious normal distribution pattern with the change of elevation and slope; settlements mostly distribute in low mountains, hills and gentle basin with an altitude of less than 1 000 m and a slope gradient of less than 15°; 83% of rural settlements are covered within 6 000 m from the river, and the river distance is negatively correlated with the number of settlements; affected by human factors, settlements are mainly located in areas with high road accessibility and convenient transportation; population economy is positively correlated with natural environment, geographical location and social agglomeration.
