當都市面對高齡化所帶來的挑戰時，以往建成環境的設計是否已具備面臨衝擊所需的彈性、已存在的社會基盤設施是否能降低其風險性，以因應高齡化的浪潮；創造高齡友善的社會，又須改善或具備哪些因子，以符合在地化樂齡永續生活空間的期待。因此本研究選擇臺北市的兩個里別，透過田野調查及問卷之方式，深入探究鄰里空間單元現今的實質環境，是否已具備成為高齡友善城市的要素，並以65歲以上高齡者之視角，評估現今鄰里空間存在哪些易致災的脆弱性位置，以做為未來優先改善的策略點。研究發現，雖然都市因為自然災害而產生重大衝擊的頻率，相較非都市地區來得低，但進一步來說，都市所面臨的風險性，其實並不僅止於自然災害，都市中日常環境的交通概況、基盤設施的分布、土地使用狀態，都存在一定程度的危險性，尤其當年長者的體力、健康狀態、反應速度逐漸下滑，其活動範圍的尺度將縮小至鄰里空間單元，因此鄰里環境設計的友善性與否，影響了高齡者面臨風險程度的高低。建物型態、大眾運輸概況、街道環境、醫療資源充足與否、社會救助的落實情形，對於打造高齡友善城市來說，將是至關重要的前瞻性評估因子。而本研究亦發現，以65歲以上之鄰里在地居民作為研究對象，更能看出鄰里空間單元，其在環境設計層面對於年長者的重要性程度。
Ageing population is an imperative problem that Taiwan and many developed countries need to face. According to the research of Ministry of the Interior, this problem not only happens in the countryside but also in many main urban areas of the world. When the urban areas expand and grow, the number of the elderly living in the urban areas increases. “Global Age-friendly Cities: A Guide” was proposed by WHO in 2007. The elderly people have many medicine support in Taiwan. However, whether our city provides the elderly a friendly living environment remains a question to be answered. Taipei is the highly urbanized capital of Taiwan. As time goes on, buildings and infrastructures could become insufficient to provide service anymore. The concept of social vulnerability index (SVI) assessment is mainly used to discuss with natural disasters, but work on social aspects of SVI is under explored. Therefore the purpose of my research is to use methods including spatial analysis, case study and interview to explore a range of social vulnerabilities which focus on the elderly people, and understand the spatial distribution of the elderly and social vulnerabilities in Taipei. This study establishs a framework which helps different cities to become safer, friendly and suitable environments for the elderly people to enjoy their lives.
