摘要

乡村聚落分布是特定地域人地关系的重要表现，探究山区乡村聚落空间分布形态是揭示山区乡村人地关系系统地域特征的重要基础工作，对优化乡村聚落分布、推动乡村振兴具有重要意义。本文以秦巴山区秦岭南段的陕西省洋县为典型案例区，综合采用栅格成本加权距离算法、地理空间分析、可达性与地理探测器方法，系统分析了洋县山区乡村聚落空间分布特征及影响因素。结果表明：洋县可达性存在明显空间差异，呈现出沿交通干线延伸的条带状分布特征，山区乡村聚落分布具有显著的低海拔与集聚指向，洋县乡村聚落多分布在南部低缓地带和中部低平地带，呈现集聚分布态势；山区乡村聚落具有显著的交通可达性空间指向性，乡村绝对数量和相对比重均随着可达性水平的提升呈逐渐增加态势。山区地域系统中，海拔、坡度、降水和气温等自然条件以及教育、医疗等社会经济条件是影响研究区乡村聚落空间分布的关键因素。未来县城和乡镇可达性对洋县乡村聚落空间分布的影响作用有望得到进一步提升，完善乡镇—县城、村域—县城的道路交通对于优化脱贫地区乡村聚落布局具有重要意义。

Abstract

The distribution of rural settlements is an important manifestation of man-land relationship in specific regions. Exploring the distribution of rural settlement space in the mountains is an important basic work that reveals the regional characteristics of the rural human-land relationship system in the mountains. This paper is based on Shaanxi Province in the south section of Qinba Mountains as a typical case area. It uses raster cost weighted distance, geographical spatial analysis, accessibility and geographical detectors to systematically analyze the characteristics and influencing factors of rural settlement space in the mountains of Yangxian County. The results show that:the accessibility of Yangxian County has obvious spatial difference, which shows the zonal distribution characteristics extending along the traffic roads. Mountainous rural settlements distribution has significant low elevation and clustering orientation. Yangxian rural settlements are mostly distributed in low-level southern and low-level areas in the south, showing the agglomeration distribution trend. The absolute number and relative proportion of the countryside have gradually increased with the improvement of the level. In the regional system of mountainous areas, natural conditions such as elevation, slope, precipitation, and temperature,as well as education and medical treatment are the key factors affecting the distribution of rural settlement space in the research area.
