Abstract:As leisure gains prominence in modern life, 'serious leisure' has emerged as a key conceptfor understanding high-quality leisure. Grounded in serious leisure theory, this studysystematically reviews its potential application in landscape architecture. It examines theconcept's connotations, measurement methods, and mechanisms of influence, analyzingantecedents, benefits (e.g., flow, well-being, place attachment), and constraints acrossindividual, activity, and environmental dimensions. Findings indicate a notable gap inresearch on objective environmental barriers. The review reveals that serious leisureexhibits a quantifiable psychological structure and continuum characteristics, and itsformation and outcomes arise from interactions among individual traits, activity attributes,and the spatial environment. Serious leisure can serve as a mediating variable linkingspatial features to psychological effects, thereby providing a foundation for constructing aspace-activity-psychology' experimental research framework.
