摘　　要：本文基于高山峡谷区—云南省大理白族自治州云龙县2003年、2013年和2023年乡村聚落居民点斑块数据,系统刻画了高山峡谷地区乡村聚落规模时空演变特征,并通过时空地理加权回归模型(GTWR)剖析了其不同因素影响的时空异质性,揭示了不同影响因素对高山峡谷地区乡村聚落规模演变的时空效应。主要研究结论如下:1)乡村聚落规模20年间扩张明显,地域特征显著;主要集中于河谷流域,呈条带状分布;聚落规模结构发展不均衡,差异性显著。2)各影响因素对云龙县乡村聚落规模影响程度不一,时空差异明显。自然环境、区位环境、社会经济环境影响因素对云龙县乡村聚落规模发展的影响效果与云龙县地域特征呈现出一致性。Based on the patch data of rural settlements in Yunlong County,Dali Bai Autonomous Prefecture,Yunnan Province,located in the alpine valley region in 2003,2013 and 2023,this paper systematically describes the spatiotemporal evolution characteristics of rural settlement scale in the alpine valley area,analyzes the spatiotemporal heterogeneity of the influence of different factors through GTWR,and reveals the spatiotemporal effects of different influencing factors on the evolution of rural settlement scale in the alpine valley area.The main conclusions are as follows:1)The scale of rural settlements expanded significantly over the past 20 years,and the regional characteristics were significant;It is mainly concentrated in the river valley basin and is distributed in a strip pattern.The development of settlement scale structure is uneven,and the differences are significant.2)The influencing factors have different effects on the scale of rural settlements in Yunlong County,and there are obvious spatial and temporal differences.The influencing effects of natural environment,location environment and socio-economic environment on the scale development of rural settlements in Yunlong County are consistent with the overall development trends observed in the county.
