| 摘 要： | 对山区乡村聚落空间分布特征进行探索,可实现乡村聚落布局优化、统筹区域发展,对改善山区居民生活水平具有显著作用。以巴中市为研究对象,利用标准差椭圆分析、核密度估算、平均最近邻指数等方法,分析了巴中市乡村聚落空间分布特征与规律,并探究了自然环境与社会经济因素对乡村聚落所造成的影响。结果表明:巴中市乡村聚落主要分布于西南区域,数量依次向外梯状递减,呈西南—东北向椭圆分布特征,中心位于巴州区东北部; 聚落总体为均匀分布类型,各县区自上而下分别呈现集聚—随机—均匀的链状分布形式,区域分布显著。巴中市乡村聚落随高程和坡度变化具有明显正态分布规律,聚落多分布于海拔1 000 m以下、坡度小于15°的低山丘陵与平坝盆地。距河流6 000 m内覆盖83%的乡村聚落,河流距离与聚落数量呈负相关。受人文因素影响,聚落主要位于道路通达性高、交通便捷的区域,人口经济与自然环境、地理位置及社会聚集性呈正相关。

| 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. |
