摘要
基于“学籍信息中的家庭地址承载了学生空间位置”这一假设,通过学籍信息收集了湖南省株洲县小学生的家庭地址,借助高德开放平台提供的地理编码和POI搜索服务,获得到了株洲县小学生的空间位置和分布,并基于最短路径分析和高斯型两步移动搜索法分析了株洲县小学教育资源的空间可达性及其特征,尝试为区域教育资源的空间均衡性分析与规划配置提供新的数据源和方法借鉴。结果表明:(1)基于学籍地址和地理编码技术能够较准确地获取株洲县小学生的空间分布。(2)株洲县小学生就近入学距离的最大值、平均值和中位数分别为11.83 km、2.10 km和1.81 km,就近入学距离小于2.0 km的学生仅占55.46%,为株洲县兼顾公平和效率的教育资源配置工作带来了挑战。(3)株洲县北部城镇地区因学校数量较多,平均就近入学距离较小,教育资源的空间可达性普遍较高,且空间差异小,均衡性好;而东南部的乡村地区,平均就近入学距离较大,教育资源的空间可达性普遍较低,且空间差异大。(4)基于情景分析,在不造成局地生源稳定性问题的前提下,新增3所学校后,东南部地区的平均就近入学距离和教育资源的空间可达性有很大的改善,龙潭镇和龙门镇的平均入学距离由3784 m和3520 m降低到3116 m和2636 m,教育资源的空间可达性分别由0.0492和0.0982提高到0.0762和0.1496。
Based on the assumption that a student home address implies a geographic location,this study retrieved the geographic coordinates and spatial distribution of primary school students by using the geocoding APIs provided by AutoNavi Information Technology Co.Ltd after collecting the registered student home addresses in Zhuzhou,Hunan province.Shortest distances through the road network from student home to all schools in the area were calculated based on the Dijkstra algorithm and the spatial accessibility of primary educational resources was assessed by using a two-step floating catchment area method.This study is aiming at providing a new method to obtain the spatial distribution of primary school students and a new viewing angle to assess the spatial equilibrium of educational resources in rural areas.Results show that:1) the geographic coordinates can be adequately obtained by using registered home addresses and geocoding APIs.2) The maximum,mean,and medium of shortest distances from student home to their nearest school are 11.83 km,2.10 km,and 1.81 km in the study area,respectively.Only 55.46% of the shortest distances from student home to their nearest school is less than 2.0 km in the study area,which rises a challenge for achieving a fair and efficient educational resources distribution.3) In the northern region of the study area,the averaged shortest distance from student home to their nearest school is generally small and the spatial accessibility of primary educational resources is uniformly high because there exist many schools.However,the shortest distances are relatively large and the spatial accessibility is low in the south-eastern region because the number of schools in this region is small.4) At last,the averaged shortest distance from student home to their nearest school was largely reduced and the spatial educational resources accessibility was highly improved in the south-eastern region of the study area in a scenario of installing three new schools.For example,the averaged shortest distance was reduced from 3 784 m and 3 520 m to 3 116 m and 2 636 m,and the spatial accessibility was improved from0.049 2 and 0.098 2 to 0.076 2 and 0.149 6 in Longtan and Longmen,respectively.
