晋中市山丘区与盆地区农村居民点空间分异特征及影响因素

Rural residential space differentiation characteristics and influencing factors of hilly regions and basin area in Jinzhong city

探索晋中市东部山丘区与西部盆地区农村居民点的空间分异特征及影响因素。提取研究区2018年变更调查库农村居民点数据,集成格网统计,借助GIS空间分析探索研究区农村居民点空间格局,通过地理探测器模型定量分析影响其规模和分布的因素。结果表明,通过分区域对比分析得出,不同地貌特征农村居民点的规模特征、景观形态特征、密度特征以及分布特征均存在明显差异;西部盆地区农村居民点规模越大形态越简单,越小越复杂,聚集性与连通性较好,全局围绕中心城区呈中间聚集、边缘稀疏的分布模式;东部山丘区则相反,农村居民点规模越小,形态越简单,空间分布相对零散,表现为小规模集聚,全局呈北密南疏的分布模式。影响因素方面,西部盆地区与东部山丘区农村居民点受各因子影响的范围与程度具有相似性与差异性并存的特征,差异性则表现在自然条件与区位特征对西部盆地区的农村居民点的空间布局具有决定性作用,对东部山丘区影响较小;经济发展水平的不同则是引起两地区差异的主要原因。不同发展阶段、经济状况和社会生活水平对农村居民点用地的空间格局产生的影响差异明显。

The spatial differentiation characteristics and influencing factors of rural settlements in eastern hilly region and western ba⁃sin region are explored in Jinzhong city.The data of rural settlements in the change survey database in 2018 are extracted and integrat⁃ed with grid statistics.The spatial pattern of rural settlements in the study area is explored by using GIS spatial analysis,and the fac⁃tors affecting its size and distribution are quantitatively analyzed by geographic detector model.The results show that through the region⁃al comparative analysis,different geomorphic features of rural settlement landscape morphology,density,distribution and coordina⁃tion of all exist obvious difference;The larger the scale of rural settlements in western basin area is,the simpler and more complex it is,with better aggregation and connectivity.The overall distribution pattern around the central urban area is centralized in the middle and sparse at the edge;On the contrary,in the eastern hilly region,the smaller the scale of rural settlements is,the simpler the shape is,and the spatial distribution is relatively scattered,showing a small-scale agglomeration,and the overall distribution pattern is dense in the north and sparse in the south.Factors influencing the basin of the west and east of the rural residential areas affected by various factors and the range of hilly region degree has the characteristics of similarity and difference coexist,the difference is in the natural conditions and geographical characteristics of the rural residential areas of the western basin spatial layout has a decisive role,in the eastern hilly region affected;Different level of economic development is the main cause of two regional differences.Different stages of development,the economy and social life level of rural residential land use spatial pattern of the impact of the difference is obvious.
