面向老龄化诉求的15分钟社区生活圈环境品质提升研究——以南京市锁金村街道为例

Research on the Improvement of Environmental Quality of 15-Minute Community Life Circle in Response to Aging Demands—A Case Study of Suojincun Subdistrict, Nanjing City

摘要: 积极老龄化背景下，建设适老化的15分钟生活圈是提升长者晚年生活质量的关键，本文旨在探究高密度老旧街区面向老龄化诉求的空间环境品质提升路径。研究以南京市锁金村街道为例，综合运用问卷实证与实地踏勘方法，从公共设施、交往空间、慢行交通与环境感知四大维度，精准量化并剖析了老年群体的真实空间需求与现存环境痛点。研究发现，该街区现状空间在适老设施复合配置水平、绿地交往有效性及无障碍慢行连续性上存在显著的供需错位。针对上述问题，本文系统性地提出了公共服务设施复合重组、绿地交往空间微更新、安全慢行网络织补及适老细节感知优化等设计策略。研究表明，基于真实诉求的精细化微更新能有效消除物理空间障碍，实现全龄友好环境重塑，可为国内其他老旧城区的适老化品质提升提供有益的实践与经验参考。

Abstract: Against the background of active aging, the construction of an age-friendly 15-minute community life circle is crucial to improving the quality of life of the elderly in their later years. This paper aims to explore the pathways for improving the spatial and environmental quality of high-density old urban neighborhoods in response to aging demands. Taking Suojincun Subdistrict in Nanjing as a case study, this research adopts a combination of questionnaire surveys and on-site investigations to accurately quantify and analyze the actual spatial needs and existing environmental problems of the elderly from four dimensions: public facilities, social interaction spaces, slow traffic systems, and environmental perception. The study reveals that there is a significant mismatch between supply and demand in the current spatial environment of the neighborhood, particularly in terms of the multi-functionality of age-friendly public facilities, the effectiveness of green space for social interaction, and the continuity of barrier-free slow traffic. In response to these issues, this paper systematically proposes a series of design strategies, including the integrated restructuring of public service facilities, micro-renewal of green social interaction spaces, the restoration of a safe slow traffic network, and the optimization of age-friendly environmental details. The results demonstrate that refined micro-renewal based on actual demands can effectively eliminate physical spatial barriers and realize the reshaping of an age-integrated friendly environment, which can provide useful practical experience and reference for the age-friendly quality improvement of other old urban areas in China.
