Different from traditional trails, urban aerial trails are limited by the carrying capacity of visitors. Therefore, it is necessary to research the recreational carrying capacity of aerial trails, in order to provide satisfactory recreational experiences to the visitors. This study took Xiamen Mountains-to-Sea Trail as the research target, and obtained the number of visitors and acceptability data based on visual assessment and questionnaire survey. Based on the data, a social carrying capacity model of the aerial trail in combination with Cifuentes' carrying capacity calculation method was proposed. The research results show that the trail's social carrying capacity is much lower than the physical carrying capacity without affecting tourists' recreational experience. The findings of this study explain the reasonable impact parameter range of the social carrying capacity, and further optimize the trail's recreational carrying capacity.

与传统步道不同，城市空中步道受到游客承载能力的限制。因此，有必要研究空中步道的游乐承载能力，为游客提供满意的游乐体验。本研究以厦门山海步道为研究对象，通过目视评估和问卷调查的方式获得游客数量和可接受度数据。在此基础上，结合Cifuentes承载力计算方法，提出了空中步道的社会承载力模型。研究结果表明，该步道的社会承载力远低于物理承载力，但不影响游客的游乐体验。
