摘要
[目的]为了解山西省农村居民点空间分布,提高农村居民点的利用率。[方法]运用Voronoi、GIS核密度方法和空间分析技术,对山西省农村居民点的空间分布特点及其影响因素进行分析,并研究山西省农村居民点的适宜性评价。[结果]山西省农村居民点分布呈现出“南密北疏”的分布特征,且主要受到自然因素的影响,尤其是受海拔、坡度、河流等因素的影响较大,其密度分布高的地区主要集中在低坡度、低海拔的区域。在区位因素上随县城、公路缓冲区距离的增加,农村居民点分布密集程度呈反比下降趋势。此外山西省农村点适宜性分布以较适宜居住为主,其中适宜性居住所占比例达到32.08%。[结论]山西省居民点分别同时受地形和区位的影响,其中地形影响较大,且整体适宜居住,文章可为优化山西省农村居民点的布局提高积极参考价值。
In order to understand the spatial distribution of rural settlements and improve the utilization rate of rural settlements. Taking Shanxi province as the research area, this paper analyzed the spatial distribution characteristics and influencing factors of rural settlements in Shanxi province, and studied the suitability evaluation of rural settlements in Shanxi province by using ArcGIS kernel density estimation and spatial analysis technology.The research were listed as follows. The distribution of rural settlements in Shanxi province was mainly in the south and greatly affected by slope, altitude and other factors. And the areas with high density distribution were mainly concentrated in the areas with low slope and low altitude. Meanwhile, with the increase of buffer distance of rivers,counties and highways, the distribution density of rural settlements showd an inverse downward trend. In addition,the suitable distribution of rural points in Shanxi province was suitable for living with the proportion of 32.08%,indicating that Shanxi province as a whole was livable. In summary, this study can provide reference for optimizing the layout of rural settlements and improving the utilization rate of rural settlements in Shanxi province in the future.
