安徽省美丽乡村空间分布特征及其影响因素研究

Study on spatial distribution characteristics and influencing factors of beautiful countryside in Anhui Province

采用基于ArcGIS10.8的最邻近指数、基尼指数等方法对安徽省526个美丽乡村重点示范村的空间分布特征进行探究,并运用地理联系率、重叠分析法等分析了其影响因素。结果表明:安徽省美丽乡村重点示范村分布呈现出聚集性和不均衡性的特征,且其在地理区域分布上存在较大差异,形成了皖南1个高密度中心,皖北1一个次密度中心,皖西以及皖中地区分布较少的格局;美丽乡村重点示范村在不同市域之间的分布差异较大,且其分布主要受到自然因素中的地形地貌和河流水系以及人文因素中的社会经济、交通区位和历史文化的影响。

Based on ArcGIS10.8,the nearest neighbor index and Gini index are used to explore the spatial distribution characteristics of 526 key demonstration villages in beautiful countryside,Anhui Province,and the influencing factors are analyzed by using geographical connection rate and overlapping analysis method.The results show that:the distribution of key demonstration villages in beautiful countryside in Anhui Province presents the characteristics of aggregation and imbalance,and there are great differences in geographical distribution,forming a high-density center in southern Anhui,a sub-density center in northern Anhui,and less distribution in western and central Anhui;the distribution of key demonstration villages in beautiful countryside varies greatly among different cities,and its distributionis mainly influenced by topography and river system in natural factors and social economy,traffic location and history and culture in human factors.
