Abstract:Under the humid and warm climate of Guangzhou, water play activities attract a broad audience, have a prolonged impact, and receive significant attention from both children and parents. Assessing user satisfaction in children's water playgrounds and proposing corresponding optimization measures based on these findings can provide a solid foundation for improving the precise construction and management of children's recreational spaces. This study selected eight water playgrounds across three children's parks in Guangzhou as the research subjects, establishing an evaluation system comprising three criteria and ten factors. Fuzzy evaluation was used to assess visitor satisfaction at each site. The research indicates a strong correlation between overall satisfaction and both the activity interest and the presence of shading facilities. Shading facilities were consistently identified as a 'low satisfaction-high importance' factor across all three types of water playgrounds. Space safety and activity interest in dry spraying type, and activity interest and environmental comfort in scenario integration type also require attention and improvement. For shallow pool immersion sites, users expressed deeper concern regarding sanitary facilities and monitoring systems, with a specific emphasis on the need for improvements to monitoring. It is recommended that targeted optimization strategies be developed based on the key characteristics and varying play needs of the three types of water playgrounds to support and enhance the creation of child-friendly outdoor environments.
