基于宜居目标的旧城区微空间适老性调查与分析--以南京市新街口街道为例

The Investigation and Analysis of the Fitness to the Aged of Micro-space in Old Town Based on the Livable Target-——With the Example of Nanjing Xinjiekou Subdistrict

中国城市旧城区人口密度高、建设强度大、绿化用地少。微空间(小型外部公共空间)因其分布密度较高、与城市生活结合紧密、使用便利的优点,深受老年人的欢迎。微空间适老性的提升是实现城市宜居目标的重要途径。通过南京市新街口街道微空间老年人的行为活动调查与空间形态的数据分析,认为步行可达性、功能性要求、小气候环境、适度的围合是提升微空间适老性的4个关键因素,而商业和交通设施则会对适老性产生抑制作用。旧城区微空间适老性的提升需要在政策管理、规划策略、设计方法3个层面进行探讨。

The old town of city in China has the characteristics of high population density, crowded construction and limited green pace. Micro-space（small public outdoor space） is popular among the aged owing to its high density of distribution, close connection to urban life and convenient use. One of the vital access to realize livable city is enhancing the fitness to the aged of micro-space. Based on the activity investigation of the aged and the analysis of spatial data in micro-space of Nanjing Xinjiekou subdistrict, the four key factors to enhance the fitness to the aged of micro-space are put forward. They are pedestrian accessibility, functional requirements, microclimate environment and moderate enclosure. Meanwhile commercial and transportation facilities will produce inhibition to the fitness to the aged.
