广西壮族自治区民族特色村寨空间分布特征及影响因素研究

Study on the Spatial Distribution Characteristics and Influencing Factors of Villages with Characteristics in Guangxi Zhuang Autonomous Region

为促进民族村寨的快速发展与保护,落实乡村振兴战略及宣传民俗文化,需分析现存特色村寨的空间分布特点及影响因素。基于广西壮族自治区97个民族特色村寨,借助ArcGIS 10.2、Geoda等相关技术软件,通过最邻近指数、核密度估计、全局空间自相关及地理探测器等方法探究广西民族特色村寨在空间上的分布特点,并分析其影响因素。结果表明:广西民族特色村寨在空间上呈凝聚分布态势,且空间集聚区数量较少,呈现出以柳州为核心的“一核多点”空间结构特征。自然地理因素中,地形起伏度、海拔高程对特色村寨空间分布有显著影响,特色村寨主要分布在海拔较高的山区中的地形较平整地区;人文经济因素中,距中心城市距离、交通条件、社会经济发展水平等是影响其空间分布的重要因素。

To promote the rapid development and protection of ethnic villages,implement the rural revitalization strategy and promote folk culture,it is necessary to analyze the spatial distribution characteristics and influencing factors of the existing characteristic villages.Based on 97 villages with ethnic characteristics in Guangxi Zhuang Autonomous Region,with the help of ArcGIS 10.2,Geoda and other related technical software,this study explores the spatial distribution characteristics of villages with ethnic characteristics in Guangxi,their influencing factors are analyzed using the nearest neighbour index,kernel density estimation,global spatial autocorrelationand geo-detector.The results show that the villages with ethnic characteristics in Guangxi are spatially cohesively distributed,and the number of spatial clusters is relatively small,showing the spatial structure of"one core and many points"with Liuzhou as the core.Among the natural geographical factors,the topographic relief and elevation have a significant impact on the spatial distribution of the characteristic villages,which are mainly distributed in the flatter areas in the mountainous areas with higher elevation;among the human and economic factors,the distance from the central city,transportation conditions and the level of social and economic development are important factors that affect their spatial distribution.
