Exploring Features of Pocket Parks That Related to Restorative Effects: A Systematic Review

To explore the relationship between features of pocket parks and restorative effects, this paper conducted a systematic review and synthesized existing empirical literature. Following the PRISMA guidelines, six databases were searched using keywords related to pocket parks and restorative outcomes. A total of 19 articles were identified. Results indicate that: (1) Research shows distinct regional phases, shifting from Northern European dominance to Asian leadership (particularly China) post-2019, with notable gaps in South America and Africa. (2) Current studies predominantly rely on cross-sectional designs and subjective assessments. (3) While existing research has evolved from initial investigations into visual landscapes and infrastructure in relation to restorative effects, expanding to encompass soundscapes and topographical dimensions, critical dimensions including nocturnal environments and intelligent technologies remain underexplored within pocket park studies. (4) Evidence confirms plant diversity, natural aesthetics, open views, enclosed boundaries, and moderate soundscapes enhance restoration, whereas excessive hardscapes and dense recreational facilities reduce effectiveness.
