Given the rapidly aging population in China, urban green spaces —fundamental environments that facilitate healthy aging—have gained increasing research signifi cance. Consequently, this study conducted a literature review by sourcing relevant research articles from the CNKI, Wanfang Data, and VIP databases. It systematically analyzed the practices and research development trends of urban green spaces in China with respect to the aging population, while also scrutinizing the content and methodologies employed in related academic studies. The results show that research on urban green spaces among China’s aging population has evolved through three distinct phases: the nascent phase (2000—2007), the growth phase (2008—2016), and the peak phase (2017—present). The national development area of urban green spaces has experienced consistent expansion, closely aligning with the upward trend observed in scholarly research on urban green spaces among an aging demographic. Under the advocacy of the World Health Organization and driven by relevant Chinese policies, the research content has expanded from the single aspects of “analysis of behavioral characteristics and needs of the elderly” and “aging-friendly design” to multi-dimensional health correlation analyses such as “evaluation of space usage and service capabilities”, “health eff ects and mechanisms of green spaces”, and “construction of aging-friendly green space systems”. Future eff orts should prioritize “active aging” as a core objective, fostering synergistic interactions between theoretical and practical innovations to advance age-inclusive, equitable, and health-promoting urban ecological environments.
