晋城市农村居民点空间分布特征及其影响因素

以山西省晋城市农村居民点为研究对象，运用GIS空间分析、核密度估计、Voronoi图法、地理探测器等方法，对居民点空间分布特征及其影响因素进行分析。结果表明：（1）居民点集聚在阳城县北部、市区中心和高平市中部，陵川县居民点分布比较分散，高平市、沁水县、阳城县和泽州县呈现为高度聚集分布；（2）高程、坡度、河流等自然因子和距离道路、中心城镇距离等人文因子影响居民点的空间分布，单因子影响最大的为高程，交互影响最大的为高程与距离中心城镇距离的交互作用。研究结果可为农村居民点合理规划和布局提供依据。

Characteristics and Influencing Factors of Spatial Distribution of Rural Settlements in Jincheng City

Taking rural settlements in Jincheng city, Shanxi province as the research object, the spatial distribution characteristics and influencing factors of settlements were analyzed by using GIS spatial analysis, kernel density estimation, Voronoi diagram method and geographical detector. The results show that : (1) settlements are concentrated in the northern part of Yangcheng county, the center of urban area and the central part of Gaoping city, and the distribution of settlements in Lingchuan county is relatively scattered, Gaoping city, Qinshui county, Yangcheng county and Zezhou county show a highly clustered distribution; (2) natural factors such as elevation, slope, river and human factors such as distance from road and distance from central town affect the spatial distribution of residential areas, the highest degree of influence of single factor is elevation, and the interaction effect distance between elevation and central town is the highest . The results can provide a basis for the layout and rational planning of rural settlements.
