安徽省传统村落地域分布特征及影响因素分析

Geographic Distribution of Traditional Villages in Anhui Province and Its Influencing Factors

选取安徽省国家级传统村落共400处和省级传统村落736处,应用最邻近指数法、不平衡指数法、核密度估计法等方法,研究对比了省级和国家级传统村落在省域层面上空间分布特征及影响因素。结果表明:安徽省传统村落的空间分布呈现核心边缘型,省域的分布呈现由南向北的明显阶梯状的差异,分布重心主要集中在皖南;市县层面,数量上黄山市拥有全省一半以上的传统村落,歙县则是全省的主要峰值聚集点;安徽传统村落集中分布在低海拔、南向缓坡,临近道路、河流、中心城市的地区。

The spatial distribution and its influencing factors of national-level and provincial-level traditional villages were studied and compared at the provincial level by selecting 400 national-level traditional villages and 736 provincial-level traditional villages in Anhui Province,using the nearest neighbor index method,unbalanced index method and kernel density estimation method.The results show that the spatial distribution of traditional villages in Anhui Province presents a core-periphery type.At the provincial level,the distribution shows obvious ladder-shaped difference from south to north,and is mainly concentrated in southern Anhui.At the municipal and county level,Huangshan City accounts for more than half of the traditional villages of the province and the number of traditional villages in Shexian County is the main peak point of the province.The traditional villages in Anhui Province are concentrated in areas with low altitude and gentle slope in the south,close to roads,rivers and central cities.
