摘　　要：学前教育是反映教育和社会经济发展的重要指标之一。基于学前教育结构POI(Points of Interest)数据,通过核密度估计法、标准差椭圆、Getis-Ord Gi*指数法实证探讨了兰州市主城区学前教育的空间分布和集聚特征。结果表明:①兰州市学前教育机构区域分布呈"东密西疏"的结构,且多集中在城关区-七里河片区。②不同尺度下,集聚特征差异明显。街道尺度下,热点区域呈多核心团状分布,冷点成零散分布;1×1km网格尺度下,热点区域多呈零散分区分布;500×500m格网尺度下,热点区域则多为集中连片状分布。研究结果可为未来兰州城市学前教育的空间合理规划和调控提供科学基础。Preschool education is one of the important carriers of education and social and economic development.Based on POI(Points of Interest) data of preschool education structure,this paper empirically analyzed the spatial distribution and clustering characteristics of preschool education in Lanzhou by means of kernel density estimation,standard deviation ellipse and Getis-OrdGi*index.The results showed that the regional distribution of preschool education institutions in Lanzhou city was in the structure of "East,close,west and sparse",and the preschool education institutions were mostly concentrated in Chengguan-Qilihe area.Under different scales,the agglomeration characteristics of the park were obviously different.At the street scale,the hot spots were distributed as multi-core clusters and the cold spots were scattered.Hot spots at1 km×1 km grid scale were mostly distributed in scattered partitions,while hot spots at 500 m×500 m grid scale were mostly distributed in centralized continuous sheets.The research results could provide a scientific foundation for the spatial planning and control of urban preschool education in the future.
