At present, the continuous improvement of urban residents' quality of life puts forward higher requirements for exploring the supply and demand of leisure walking. Against this background, this study focuses on leisure walking, taking the 15-minute community life circle as the space-time scope to re-examine the cumulative health effect of leisure walking as physical activity. Additionally, this study constructs a research framework to highlight the comprehensive benefits of leisure walking, including space-time opportunity and health promotion. Based on the research framework, this study uses comprehensive survey data from relevant communities in Nanjing to conduct an empirical study on the characteristics and influencing factors of leisure walking. The results show that the leisure walking of most residents makes it difficult to obtain comprehensive benefits, including space-time opportunity and health promotion. The built environment of the 15-minute community life circle significantly affects leisure walking based on the comprehensive benefits of space-time opportunity and health promotion. Specifically, the dense distribution of walkable paths has a promoting effect on overall residents and residents based on age and income stratification. In contrast, high-density population distribution and living locations far from the city center have an inhibitory effect. In addition, dense parks, high green coverage, and good public space accessibility positively affect stratified residents. The influence of individual attributes involves three aspects: socioeconomic attributes, health status, and family socioeconomic attributes. Specifically, overall or stratified residents with flexible and abundant leisure time and family members' accompanying behavior are more likely to participate in leisure walking and obtain more health benefits in a shorter space-time range. However, affected by the limited leisure time and poor physical condition, overall or stratified residents with a higher level of personal monthly income, families with children ( |
