传统村落空间分布特征及影响因素研究:以江苏省为例

Study on the spatial distribution characteristics and influencing factors of traditional villages:taking Jiangsu Province as an example

为探究传统村落空间分布与自然和社会要素间的关联性,本文以江苏省502个传统村落为研究样本,利用最近邻指数、核密度估计、标准差椭圆对传统村落空间特征进行了分析,并运用地理探测器等方法对其影响因素进行了探讨。结果表明:1)江苏省传统村落在空间分布上呈现集聚分布状态;2)传统村落密度分布差异显著,总体呈“南密北疏”特征;3)传统村落分布随批次变化呈西南-东北方向收缩态势,在西北-东南方向呈一定的扩张趋势,空间分布由西南转向东北方向;4)人口密度、文物保护单位密度、人均GDP、平均坡度是影响传统村落分布的主导性因素,且任意影响因素交互作用强于单一因素独立作用。

To explore the relationship between the spatial distribution of traditional villages and natural and social factors,this paper takes 502 traditional villages in Jiangsu Province as research samples,analyzes the spatial characteristics of traditional villages by using nearest neighbor index,kernel density estimation and standard deviation ellipse,and discusses the influencing factors by means of geographic detector.The results show that:1)the spatial distribution of traditional villages in Jiangsu Province shows a state of agglomeration;2)there is a significant difference in the density distribution of traditional villages,generally showing the characteristics of"dense in the south and sparse in the north";3)the distribution of traditional villages shrinks in the southwest-northeast direction with the batch change,showing a certain expansion trend in the northwest-southeast direction,and the spatial distribution changes from the southwest to the northeast;4)population density,unit density of cultural relic conservation,per capita GDP and average slope are the dominant factors affecting the distribution of traditional villages,and the interaction of arbitrary factors is stronger than that of a single factor.
