基础教育资源空间分布特征研究——以兰州市城关区小学为例

Research on the Spatial Character of Primary Educational Facilities——Taking Chengguan District Primary School of Lanzhou as an Example

运用数据可视化、OD成本分析和两步移动搜索算法等方法,以可获取的兰州市城关区各小学为研究对象,区内各街道行政区划为基本研究单元,分析小学空间分布特征、服务能力及各街道的小学可达性。研究结果表明,区内小学教育资源供给及可达性呈现由中心向边缘地区逐渐递减的整体趋势;小学学位供给量与所在街道适龄儿童需求对应不平衡;城关区内各小学在阈值范围内的服务能力强弱差距较大;可达性整体呈现由中心区域向边缘递增的空间分布特征,西部地区可达性相对东部地区较高。

This paper uses data visualization,OD cost analysis and two-step mobile search method.Taking available the primary schools in Chengguan district of Lanzhou as the research objects,the subdistrict offices in Chengguan district were taken as the basic research unit.This paper is devoted to analyzing the spatial character and service ability of primary schools and accessibility of primary schools by districts.The results showed that the primary education resources and accessibility show a decreasing trend from the district center to the surrounding areas.There is an imbalance between the supply of primary school degrees and the demand of school-age children in the neighborhood.The service ability of each primary school has larger difference within the threshold range.The accessibility shows a increasing trend from the district center to the surrounding areas and western region is higher than that of eastern region.
