城市森林环境对正负情绪状态影响的Meta分析

明确城市森林环境对正负情绪状态的影响程度及影响因素,为城市森林建设提供科学依据。对Web of Science和CNKI数据库进行检索,对最终纳入的文献采用Meta分析的方法,研究城市森林环境对正负情绪状态的影响。结果表明,纳入的17篇文献中有13项随机对照试验,21项自身前后对照试验,文献质量一般;进入森林对积极情绪影响的总效应量SMD=0.33,I²=33%,95%置信区间Cl[0.23,0.44];进入森林环境对消极情绪影响总效应量SMD=-0.35,I²=0,95%置信区间Cl[-0H46,-0.25];与城市环境相比,处于城市森林对积极情绪状态总效应量SMD=0.59,I²=42%,95%置信区间Cl[0.44,0.75];对消极情绪的影响总效应量SMD=-0.45,I²=0,95%置信区间Cl[-0.61,-0.30],城市森林对积极情绪影响效果的异质性来源主要为心理健康程度和城市森林自然环境。综上所述,城市森林环境对人的心理健康有积极促进效果,进入森林环境后可降低人的消极情绪,心理健康状态和城市森林自然环境影响城市森林对积极情绪的提升效果。

Meta analysis of effects of urban forest enviroment on positive and negative emotional states

In order to clarify the influence degree and influencing factors of urban forest environment on positive and negative emotional states, the study put forward reasonable suggestions for forest health care construction. The effects of urban forest environment on positive and negative emotional states were studied by searching Web of Science and CNKI databases and Meta analysis of the included literatures.The result showed that, among the 17 included literatures, 13 randomized controlled trials and 21 self-controlled before and after trials were conducted, and the quality of the literature was mediocre; The total effect size of the impact of entering the forest on positive emotions was SMD=0.33, I²=33%, 95% confidence interval Cl [0.23, 0.44]; The total effect size of entering the forest environment on negative emotions was SMD=-0.35, I²=0, 95% confidence interval Cl [-0.46,-0.25]; Compared with the urban environment, the total effect of being in an urban forest on positive emotional state Quantity was SMD=0.59, I²=42%, 95% confidence interval Cl [0.44, 0.75]; Total effect size on negative emotions was SMD=-0.45, I²=0, 95% confidence interval Cl [-0.61,-0.30], the source of heterogeneity in the effect of urban forest on positive emotions was the degree of mental health and the natural environment of urban forest. In conclusion, urban forest environment had a positive effect on people's mental health. Entering the forest environment could reduce people's negative emotions. The mental health status and urban forest natural environment affected the urban forest′s effect on improving positive emotions.
