Taking Jinshan District in Shanghai as a case study, this paper evaluates the status quo of community health services from the "demand-supply" perspective, and finds a remarkable difference in the needs among different age groups, a big gap between urban and rural areas in the coverage degree of facilities, and different challenges for public service at the "prevention – treatment – health care" stages. It further puts forward several planning strategies involving(1) specific service supply based on different age groups,(2) "15-minute health service cycles" in both urban and rural communities,(3) adjustment of facilities to local conditions, and(4) promoting the quality of health services. Furthermore, it discusses in-depth issues underlying planning policies, such as the innovation of service content, the integration of different plans, and the cultivation of health service needs.展开更多

Current research on basic public service facilities focuses on equal spatial distribution, leading to the overlook of their match with the surrounding built environment. Based on a case study on education, healthcare, and elderly care facilities in Chengdu central urban area, this paper analyzes the spatial distribution of these facilities and the built environment, and examines their spatial matching degree using a bivariate spatial autocorrelation model. The findings reveal the following insights: firstly, education and healthcare facilities present a “one core and multi-center” spatial distribution pattern, with the city center serving as the core and suburban subdistricts acting as the multiple centers, while elderly care facilities present a core-edge distribution pattern in contrast;secondly, the built environment presents a core-edge radial distribution pattern, with the city center acting as the nucleus that connects suburban subdistricts;thirdly, the spatial matching degree between the facilities and the urban built environment from the city center outwards is characterized by high, low, medium, and high levels. Notably, a significant spatial mismatch is observed in urban-rural transitional zones. In light of these findings, the paper comes to a conclusion that during urbanization, the efforts to equalize basic public service facilities in the urban-rural transitional zones may lead to spatial mismatches, to which urban planners and managers should pay close attention.展开更多
