Abstract：As an activity that satisfies people's physical and mental health and pleasure,recreational behavior is essential for urban residents to obtain happiness.All-age-friendly development is a crucial goal of urban community construction.Particularly,the needs of the vulnerable must always be fully considered.In the context of the current structural changes in urban population,on the one hand,the refined allocation of community recreation space under the all-age-friendly goal is an important issue to improve the quality of urban space.In contrast,it is a concrete embodiment of the people-centered urban construction concept. Firstly,the relationships between age groups,vulnerable group types,recreational behaviors,and recreational space were established.The applied data was introduced,including actual population data,recreational space vector data and transportation network data.Specifically,actual population data was the new urban data type with spatial and attribute granularity refined to individuals of independent populations in the city.It is fundamental to realize all-age-friendly refined allocation of recreational space,which can consider vulnerable people. On this basis,a quantitative recreational space allocation and optimization model based on characteristics of the crowd activity under the all-age-friendly goal was developed.It comprised estimating recreational space demand scale,layout evaluation,and optimization allocation.During the recreational space demand scale estimation,all age and vulnerable groups were divided based on the actual population data and connected with recreational behaviors.The demand scale of recreational space was estimated by combining the simultaneous rate and priority coefficients.During layout evaluation and optimization allocation,a network analysis was carried out based on road network data and recreational space data,getting the single-group coverage rates and comprehensive population coverage rates for 5-minute,10-minute and 15-minute recreational space service areas.The service status of community-level recreational spaces was revealed by combining single-group coverage rates and demand scales.The recreational space supply level could be gained by combining comprehensive population coverage rates and demand scale.Finally,the supply level was evaluated comprehensively,combined with the supply scale,and optimization strategies for allocating recreational space were proposed. The scales and spatial distributions of all age groups and vulnerable groups were extracted from the age and gender attributes of the actual population.On this basis,an empirical study regarding refined quantitative allocation of recreational space based on actual population data was carried out in the surrounding areas of the central axis of Guangzhou City.It demonstrated that the existing recreational space scale in the central axis area of Guangzhou City met the demand scale,and the comprehensive population coverage rate reached 90％of the target value.The old and the pregnant-infant groups were completely addressed within the 10-minute walking space,but incompletely within the 5-minute space.Such differentiation was attributed to insufficient recreational spaces and insufficient road network construction.Hence,recreational spaces must be added to the study area's southern part of Shipai Street,Xinqing Village,Xian Village,and surrounding areas of the Dongxing Community. Finally,evaluating community-level recreational space for all ages and vulnerable groups could be refined based on actual population data.Research conclusions could support the reasonable and scientific planning of community-level recreational spaces.
