成都旧城小学所在街道空间更新范围研究

Study on the Spatial Renewal Range of the Streets Located by the Primary Schools in the Old Town of Chengdu

当前我国儿童友好型城市建设的街道更新研究中,对于旧城小学所在街道的研究范围参照《城市居住区规划设计标准》(GB 50180—2018)的500 m的小学的服务半径,而旧城居住人口和小学密度较大,此范围不够精确,易造成资源浪费和研究结论不够准确。文章以成都市为例,将旧城范围内的小学所在街道进行分类,选取代表小学,基于GPS技术跟踪选取小学生的放学路径,分析总结出旧城小学生在点状、线状、面状空间的活动范围特征,对今后的旧城儿童友好型街道更新研究范围提供新的思路。

In the current street renewal research of child-friendly urban construction in China,the research scope of the streets where the primary schools in old town of the city are located refers to the service radius of 500m from primary school in the Urban Residential Area Planning and Design Standards(GB 50180—2018),while the density of the population and primary school in the old city is large,this range is not accurate enough,which is easy to lead to the waste of resources and inaccurate research conclusion.Taking Chengdu as an example,the streets where primary schools in the old city are located are classified,representative primary schools are selected,and the leaving paths of the students from primary schools are selected based on GPS technology.Then the characteristics of the activity range of primary school students in point,line and surface space in the old city are analyzed and summarized,which provides new ideas for the future research scope of child-friendly street renewal in the old city.
