摘要
本文基于百度地图API调用开放的网络数据,从供需角度测算西安市三环内主城区的学校可达性及学校与住宅的供需匹配情况,并通过最短时间距离法测算学校的空间可达性,用因子空间叠置法测算学校可达性与小区兴趣点(POI)数据的供需匹配程度。研究结果表明,西安市三环内主城区内的学校总体可达性较高,小学的整体可达性优于中学。从街道尺度看,小区与学校的空间可达性由一环向二、三环逐渐下降,一环内学校可达性最优,三环内学校可达性水平较高;从环线尺度看,二环内小区的整体可达性较佳,步行用时也较短,到达距离最近的学校可达性大于97%,二、三环内到达距离最近学校的小区大于58%,绝大多数高需求地区均具备相对较高的学校可达性。
The accessibility of the main schools and the matching and housing supply and demand in the main city within the third ring roads in Xi'an City is estimated in this paper from the perspective of supply and demand and based on the open network data from Baidu Map API.The spatial accessibility of schools is measured by using the shortest time distance method,the supply and demand matching degree between schools accessibility and point of interest(POI) data of the residential areas are estimated by using the factor superposition method.The results showed that the accessibility of schools in the study area was generally higher,with overall accessibility in primary schools better than secondary schools.From the perspective of street,the spatial accessibility of residential areas and schools is gradually declining from the first ring roads to the second and the third ring roads,the accessibility within the third ring roads is better;while,from the perspective of the ring roads,the accessibility within the second ring roads is much better,the walking time is shorter,and the accessibility to the nearest schools is greater than 97%,and the second and third ring roads are greater than 58%,and the vast majority of high demand areas have relatively high accessibility of schools.
