摘　　要：地理环境影响线性文化廊道沿线古村镇空间分布。当前研究多在全局尺度下对聚落空间分布特征进行分析,难以准确阐明线性文化廊道在地理环境和文化交往影响下聚落的空间模式变化。本文主要运用MGWR方法,以南方丝绸之路四川段沿线古村镇为研究对象,在历史考据和空间分析的基础上对南方丝绸之路路线演变过程进行分析,并分别从全局尺度、支线尺度和邻域尺度提取地理环境影响下南方丝绸之路四川段沿线的古村镇空间分布特征,进一步解释地理环境对古村镇分布影响的尺度效应。研究结果表明:(1)全局尺度上,古村镇主要集中分布在地形起伏度和坡度较小、海拔较低的岷江、沱江冲积平原,以及青衣江、大渡河冲积平原地区,其次为成都平原向川西高原山地过渡带的河口河谷区;(2)支线尺度上,古村镇在南方丝绸之路西线、中线和东线分别呈现“L”型、“U”型和“」”型的分布特征;(3)邻域尺度上,古村镇在不同地貌环境区呈现出低水平均衡阶段(带状型)、极核发展阶段(放射型)、扩散阶段(组团型)和高水平均衡阶段(网络型)4种图谱构型;(4)地理环境对古村镇的影响在地理空间上存在滞后现象与溢出效应,海拔、坡度、地形起伏度等地貌特征差异对古村镇分布产生基础性作用,河流邻近性对古村镇分布产生限制或促进作用。本研究对揭示廊道文化传播和地域环境作用下的聚落空间分布形成机制具有重要意义。Geographical environment governs the spatial distribution of ancient villages and towns along linear cultural corridors.Although past research mostly stressed the spatial distribution of ancient settlements on a global scale,it was difficult to accurately clarify the changes in spatial pattern of settlements under the influence of linear cultural corridor geographical environment and cultural communication.In this study,it took the ancient villages and towns along the Sichuan section of the Southern Silk Road as research object.Based on historical document research and GIS spatial analysis,as well as multi-scale geographical weighted regression,the evolution process of the southern Silk Road route was analyzed to outline the influence characteristics of geographical environment on the spatial distribution of ancient villages and towns under different scale effects.The following results are found:(1)On a overall scale,ancient villages and towns are mainly distributed in the alluvial plains of the Minjiang River and the Tuojiang River,the Qingyi River and the Dadu River,where there are small topographic relief or slope,with low altitude,followed by the estuary and valley area in the confluence of Chengdu plain to Western Sichuan Plateau.(2)On a branch scale,the distribution of ancient villages and towns are in the shape of“L”,“U”and“」”in the west route,middle route and east route of the Southern Silk Road,respectively.(3)On a neighborhood scale,ancient villages and towns describes four patterns in different geo-environment areas,namely low-level equilibrium stage(band type),polar nuclear development stage(radial type),diffusion stage(cluster type)and high-level equilibrium stage(network type);(4)The influence of geo-environment on ancient villages and towns has lag phenomenon and spillover effect in geographical space.Differences in geomorphological characteristics such as altitude,slope and fluctuation had a basic effect on the distribution of ancient villages and towns,and proximity to river has a f
