Exploring the restructuring mechanism and planning approaches of community living circle under the guidance of healthy cities: A case study of Xi'an High-tech Zone

Under the Healthy China strategy, the community living circle has become a new approach to the rational allocation of medical and health resources and reconfiguring health service delivery. By systematically analyzing the collaborative mechanism between the healthy community living circle and the healthy city, using POI data and remote sensing imagery to identify urban health resources, and employing the two-step moving search method and the Shannon-Weiner diversity index, this study investigated the spatio-temporal distribution characteristics of health resources in the High-Tech Zone of Xi'an, thereby rationally allocating health resources and optimizing the supply of service facilities. The research findings are as follows: ①The mutual cooperation between humans and the environment is the core of the healthy community living circle. Reconstructing the healthy community living circle requires an integrated approach that includes the material environment as the foundation of health, the facility carriers that ensure the continuity of health, and the shared and co-governed spatial management. This creates a coupled framework for the concept of a healthy city collaborative living circle, promoting a shift in the construction approach from a non-damaging health perspective to an active intervention. ② The evaluation indicators for health resources are complex. By analyzing the pathways through which supporting facilities affect health, they are integrated into accessibility of health resources, efficiency of safety and disaster prevention, friendliness of daily activities, and guidance of healthy humanities. Through further refinement of these indicators, the evaluation system for the healthy community living circle is reconstructed. ③ The distribution of facilities is closely related to their geographical locations, with significant differences between different types of facilities. The impact of facility accessibility on the reconstruction of healthy communities decreases with the centrality. ④ The related planning of a healthy city and the reorganization of living circle planning require a clear planning process, the construction of a resilient transmission system, and the optimization of the spatial composition of each level of living circle, with differentiated needs being met through graded and categorized supply.
