摘　　要：乡村振兴战略实施背景下,研究山区乡村聚落的分布特征和影响因素,对乡村聚落布局优化和“和美乡村”乡村建设意义重大。本文中以川西北高原乡村聚落为研究对象,利用核密度、平均最邻近指数及位序-规模法则等方法,分析乡村聚落空间分布特征,并借助基于最优参数的地理探测器模型探索驱动因素。结果表明:①川西北高原乡村聚落集中分布特征显著,东缘密度最高,并呈从东缘向中部逐渐递减的分布规律;②乡村聚落整体符合位序-规模法则,规模差异较大,面积集中于高位序聚落,低位序聚落规模较小,而各个县之间乡村聚落规模差异较小,位序较高城镇的乡村聚落规模并不突出;③社会经济因素是影响川西北高原乡村聚落空间异质性的主导因素,自然环境因素对其影响也较为深刻,各个驱动因子之间存在协同增强效应,尤其是社会经济因素和区位条件因素之间增强效应尤为显著,对研究区乡村聚落异质性影响较为深刻。研究成果为该地区乡村聚落重构优化和高质量发展提供数据支撑。Under the strategy of rural revitalization,efforts to study distribution characteristics and influencers of rural communities in mountainous areas is of great significance to improve rural communities and build harmoniously beautiful villages.Taking the northwest plateau of Sichuan as the research object,we analyzed the spatial distribution characteristics of rural communities by studying nuclear density,average proximity index and position rank-size rule,and revealed its driving factors using the optimal parameters-based geographical detector model.The distribution of rural communities in the northwest plateau of Sichuan was geographically concentrated,with the highest density in the eastern rim and decreasing gradually from the eastern rim to the central one.Rural communities as a whole were in keeping with the rank-size rule,while their size varied greatly.The area of the high-rank communities is larger than that in low-order communities.There is little difference in the scale of rural communities among counties,and the scale of rural communities in high-order counties is not prominent.Socio-economic factors are the leading factors affecting the spatial heterogeneity of rural settlements in the Northwest Sichuan Plateau,and the influence of natural environmental factors is also profound,and there are synergistic enhancement effects between various driving factors,especially the enhancement effect between socioeconomic factors and location conditions,which has a profound impact on the heterogeneity of rural settlements in the study area.The research results provide data support for the reconstruction and optimization of rural settlements and the high-quality development in this area.
