In the context of intensive land use in mountainous cities, community sports parks have emerged as a new type of open public space. These parks are created by flexibly repurposing underutilized urban spaces, such as corner lots, primarily for physical exercise and leisure fitness activities while also serving general community park functions. This study aims to quantitatively evaluate the landscape Vitality of community sports parks in mountainous cities from the users' perspective, providing a reference basis for their planning, design, and optimization. Three newly constructed community sports parks of similar scale in Chongqing were selected as research samples. The Semantic Differential (SD) method was employed to establish 14 evaluation factors, and correlation analysis was used to analyze the data. The study reveals that the average scores for all evaluation factors of the sample parks were 2.00, 1.76, and 2.33 respectively, indicating overall satisfaction among evaluators. Accessibility, attraction, facility, and greenery were identified as key factors determining landscape Vitality and satisfaction. Shade and creativity generally received lower scores. Future planning and design should focus on improving ideal transportation accessibility, reasonable terrain management, affordance of environmental elements, and atmosphere of local historical and cultural. This landscape Vitality evaluation of community sports parks provides reference and optimization suggestions for landscape construction. It contributes to improving the quality and utilization efficiency of public spaces in mountainous cities, thereby promoting urban sustainable development and enhancing residents' health levels.
