A Meta-analysis of Restorative Nature Landscapes and Mental Health Benefits on Urban Residents and Its Planning Implication

为了系统性验证这种修复作用的效果,本文根据相关关键词和两篇 标志性论文引用筛选出 63 篇相关论文,并在此基础上对其中描述统 计数据汇报完整的 21 篇文献结论进行了量化荟萃分析。文献证据表 明,人们主观上认为短时自然体验具有恢复性(标准化均值差 SMD, Standardized Mean Differences=1.28),自然的这种恢复性在具体健康影 响上主要体现在对情绪的有效调节(SMD=1.37)和对压力的有效减低 (SMD=-1.00),但对以注意力为主认知能力改善的文献证据,目前尚 不明显(SMD=0.10)且仍存在一定矛盾,需要近一步研究。 Abstract: Evidences suggest that a negative impact of urban built environment on residents’mental health, while nature environment reveals a restorative effect on this negative impact. This study extracts 63 related papers based on keywords and citation tracking of two key references, and examines 21 literatures with complete descriptive statistics through quantitative metaanalysis. Results reveal that nature restorative effect is perceived after shortterm exposure (Standardized Mean Differences, SMD=1.28).The health benefits of nature are primarily found in emotion regulation (SMD=1.37) and arousal/stress reduction (SMD=-1.00). The impact on attention and related cognitive performance is insignificant (SMD=0.10) with conflicting results which require further investigation.
