基于GPS技术的小学生放学路径调查与学区服务半径研究

摘要

Recently, many social problems have emerged in the school district and service radius of primary schools. Based on the distribution of schools in Heifei, the research uses the Thiessen Polygons method to generate new school districts and to follow the path to home after school of pupils with GPS. Then data is mapped into action diagram, with a comparison between trajectories and action circles. The study points that the service radius of primary schools, which mostly limit between 500 to 800 meters, overlapping in the central part of urban area while this indicator is over large in the periphery and new urban area. This research suggests the distribution for the future planning of primary schools.%目前国内许多城市小学的学区范围与服务半径存在诸多问题，研究基于合肥市小学学区调研，应用泰森多边形法生成新的学区范围，并使用GPS技术对合肥市三所小学小学生放学路径进行追踪调查，将行为轨迹图与行动圈示意图对比，发现城区中心部分小学服务半径过小有重叠，而城区外围及新城区部分小学服务半径过大，小学生放学路径大都集中于500m行动圈内，很少会超过800m行动圈。研究指出当前城市小学学区空间存在的问题，并对今后城市小学规划布点、学区划分与服务半径设置提出改进建议。
