摘要
为了更好地实施土地节约集约利用、促进新型城镇化建设,以平坝县2017年土地利用现状数据和DEM数据为基础,运用农村居民点用地比重、核密度估计和缓冲区分析相结合的方法对平坝县农村居民点空间分布特征及其影响因素进行研究。结果显示:平坝县农村居民点规模较小;农村居民点用地比重为2.71%,为较密集分布;基于核密度估计发现平坝县农村居民点有多个核心热点区,呈现"中部、中部偏西北部密集,东南部和西北部稀疏,其余区域散布"的空间格局;平坝县农村居民点的空间分布受海拔、坡度、河流以及县乡道因素的影响。
In order to better implement land conservation and intensive use,and to promote new urbanization construction,we adopted the methods of rural settlement land use proportion,core density estimation and buffer zone analysis,and studied the spatial distribution characteristics and influencing factors of rural settlements in Pingba County based on the land use status data and DEM data of Pingba County in 2017. The results showed that: the scale of rural settlements in Pingba was relatively small;the proportion of rural settlement land use was 2. 71%;there were several core hotspots of rural settlements,distributed densely in the central and central-northwest areas,sparsely in the southeast and northwest areas,and scattered in other areas;the spatial distribution of rural settlements in Pingba County was influenced by the altitude,slopes,rivers,and county roads.
