黄河流域传统村落空间分布特征及其影响因素研究

Spatial distribution characteristics of traditional villages in the Yellow River basin and influencing factors

以黄河流域673个国家级传统村落为研究对象,借助ArcGIS等工具,运用最邻近指数、不平衡指数、核密度估计值、地理探测器等方法探讨黄河流域传统村落的空间分布特征及其影响因素。结果表明:1)黄河流域传统村落空间分布为凝聚型,省际分布不均衡,总体呈现"大集聚、小分散"的分布格局,主要形成以青海省、山西省为主的两大高密度区;2)自然地理条件是影响黄河流域传统村落空间分布的首位因素,其次是社会经济因素。其中,河网密度、年降水量、公路密度、人均GDP是影响黄河流域传统村落空间分布的主要因素。

Taking 673 national traditional villages in the Yellow River basin as the research object, the spatial distribution characteristics of traditional villages in the Yellow River basin and influencing factors were explored by methods of nearest neighbor index, imbalance index, nuclear density estimation, geographical detector by ArcGIS and other tools. The results show that: 1) The spatial distribution of traditional villages in the Yellow River basin is characterized by agglomeration, but unbalanced. Distribution pattern shows as "large agglomeration and small dispersion";high density areas are mainly in Qinghai province and Shanxi province. 2) Natural geographical condition is the primary factor affecting spatial distribution of traditional villages in the Yellow River basin, followed by social and economic factors. Among them, river network density, annual precipitation, highway density and per capita GDP are the main factors for the spatial distribution of traditional villages in the Yellow River basin.
