摘　　要：为了解延安市宝塔区农村居民点空间分布情况,对土地进行集约高效利用,避免农村居民点布局分散,提升居民点的发展潜力,以宝塔区三调数据库和DEM数据为基础,结合Voronoi图、核密度估计和缓冲区分析方法,并借助地理探测器,分析研究宝塔区农村居民点空间分布特征及其影响因素。结果显示:宝塔区农村居民点在乡镇级尺度上,CV值均在64%以上,呈集群分布;在村级尺度上,除5个无法计算CV值的村,90.14%的农村居民点的CV值>64%,呈集群分布;通过核密度估计发现宝塔区农村居民点的分布趋势总体上表现为“东北部密集,西北部、南部稀疏”;宝塔区农村居民点空间分布受到高程、坡度、道路、河流的共同影响。In order to understand the spatial distribution of rural settlements in Baota District,Yan'an City,make intensive and efficient use of land,avoid scattered distribution of rural settlements,and improve the development potential of settlements,the spatial distribution characteristics and influencing factors of rural settlements in Baota District were analyzed and studied based on Baota District's three-adjustment database and DEM data,combined with Voronoi diagram,kernel density estimation and buffer analysis methods,and with the help of geographic detectors.The results show that:at the township-level scale,the CV values of the rural settlements in Baota District are all above 64%,showing a cluster distribution;at the village-level scale,except for 5 villages where the CV value cannot be calculated,90.14%of the rural settlements have a CV value of>64%,showing a cluster distribution;The distribution trend of rural settlements in Baota District is generally“dense in the northeast,sparse in the northwest and south”through kernel density estimation;the spatial distribution of rural settlements in Baota District is jointly affected by elevation,slope,roads and rivers.
