随着我国老龄化加快发展，老年人空间问题日益凸显。为了适应老龄化社会需求，本课题以老年人服务设施可达性为切入点，以老年人口和服务设施空间互动发展为核心目标，探索老年人服务设施规划布局策略。基于人口-空间互动"自上而下"的宏中观层面，运用GIS技术探索城市老年人的空间分布特征、演变趋势；运用相对可达性指标定量化测度老年人服务设施的可达性；运用社会生态学方法摸清老年人服务设施在生态区位竞争中的现象、表征，探索老年人服务设施错位发展、边缘化、不均衡分布等现象的内在机制。基于人口-空间互动"自下而上"的微观层面，运用质性研究方法、认知行为方法研究城市老年人的日常行为活动特征和需求，分析其对老年人服务设施空间布局的影响，并探索基于老年人口与服务设施空间互动发展的城市老年人服务设施规划布局策略，为科学的开展老年人服务设施规划提供重要依据，为推动城市规划向着理性决策规划和多元社会空间协调规划发展奠定基础。

With the accelerated development of China's aging population, the spatial problem of elderly people has been highlighted day by day. In order to meet the social demand of aging population, this study starts with the accessibility of public service facilities for the elderly, and tries to search for some reasonable strategies about the planning layout of these facilities, with the main target of interacting development of elderly population and service facility space. Based on the top-down macro&meso-perspective of population-space interaction, the study searches for elderly space distribution characteristics and the evolution trend with the use of GIS technology; quantitatively estimates the accessibility of elderly service facilities with the use of relative indexes; finds out the appearances and characteristics of elderly service facilities competing in ecological location with the use of social ecology, and searches for the internal mechanism of vicarious development, marginalization and inhomogeneous distribution of elderly service facilities.Based on the bottom-up micro-perspective of population-space interaction, the study uses the methods of qualitative research and cognitive behavior to obtain the daily behavior characteristics and demands of the elderly. With the analysis of the spatial layout influence of elderly service facilities, the study searches for the planning layout strategies of the facilities based on the interacting development of elderly population and service facility space, which tries to provide important principles to carry out scientific planning of the facilities and to lay a solid foundation that promotes to transform urban planning into public policy-making planning and diversely coordinative society and space planning.
