摘　　要：探究传统村落的空间可达性与分布特征,对科学保护传统村落和促进乡村振兴具有重要的理论与现实意义。运用数理统计分析和空间分析方法,对甘肃省传统村落的空间可达性、分布特征及其影响因素进行研究。结果表明:1)传统村落的空间可达性总体不佳,全局可达性高的村落在天水、兰州形成了高密集区和次高密集区,局部可达性高的村落主要分布在天水、兰州、酒泉和陇南等市。2)国家级、省级及所有传统村落均呈凝聚型分布,县级尺度上的分形特征较明显,并呈现出沿某一地理线集中分布的态势。3)传统村落整体表现出“东南密、西北疏,强集中、大分散”的空间格局,高密度区位于天水—陇南地区。4)传统村落的空间分布受到自然地理条件和人文社会因素的共同约束。年均降水量、人均GDP、人口密度和路网可达性4个因子的影响力较强,但任意两个因子的交互影响均大于单个因子,尤其是年均降水量与人均GDP、人口密度与非物质文化遗产数量。Exploring the spatial accessibility and distribution characteristics of traditional villages has significant theoretical and practical significance for scientifically protecting traditional villages and promoting rural revitalization.Using mathematical statistical analysis and spatial analysis methods,this paper presented the study of spatial accessibility,distribution characteristics and its influencing factors of traditional villages in Gansu Province.The results show,1)in general,the spatial accessibility of traditional villages is poor.Villages with high global accessibility have formed high-density areas and sub-high-density areas in Tianshui and Lanzhou,but villages with high local accessibility are mainly distributed in Tianshui,Lanzhou,Jiuquan and Longnan.2)The spatial distribution types of traditional villages at different levels are all agglomerative,their fractal characteristics at the county level are more obvious,which suggesting a concentrated distribution along a geographic line.3)The overall distribution of traditional villages shows a spatial pattern,which is“dense in the southeast,sparse in the northwest,strong concentration,and large dispersion”,and their high-density area is in the mixed area of Tianshui and Longnan.4)The spatial distribution of traditional villages is affected by natural geographical conditions and social factors.Among them,the four factors of average annual precipitation,per capita GDP,and the interaction between population density and road network accessibility have strong influences,but the interaction effect of any two factors is greater than that of a single factor,especially the interaction between the average annual precipitation and per capita GDP,and the interaction between population density and the number of intangible cultural heritage.
