Abstract

As the most important place for residents' daily leisure, the planning, layout and service level of urban recreational facilities are closely related to the quality of urban life. Taking national leisure as the benchmark and big data as the background, through the integration of POI data, vector building contour data and OSM road system data, combined with field survey, Tyson polygon is introduced to partition the urban recreational facilities in Guandu section of Baoxiang River Basin, build the urban recreational facilities system, and carry out the evaluation dimension from three aspects: quality, accessibility and coverage of urban recreational facilities, According to the main problems existing in this area, optimization suggestions are put forward, including improving the type of recreational facilities, adding the number of recreational facilities, paying attention to the fairness of recreational facilities and so on. This study has some limitations in the research scope, service scope and service population, but in view of the complex construction of the research scope, rich cultural types and certain representativeness, it can provide some reference for the evaluation and optimization of recreational facilities in similar regions.
