Abstract: Public parks, critical components of public space, have become increasingly important with accelerating urbanization and rising living standards． Driven in recent years by advanced urban open space theory and new technologies, design and evaluation of parks have moved beyond constraints of meeting singular functional indicators． Park vitality has become a critical issue in urban planning and landscape design, but a unified consensus on theoretical framework and assessment methodologies has not been established． Progress in park vitality research, including definition, measurement methods and influencing factors are systematically reviewed in this study． A triadic interaction framework of “residents-parks-built environment” is proposed to elucidate mechanisms underlying formation of park vitality． Preliminary methodologies for assessing park vitality are explored. In the future, interdisciplinary integration should be emphasized, multi-source data analysis methods should be optimized． Precision and equity of park planning should be enhanced, future parks should be more effective to enhance the well-beings of residents．
