大自然的体验提供了许多心理健康的好处，特别是对生活在城市地区的人。城市居民社区的自然特征可能是他们接受的每日自然剂量的关键决定因素;然而，哪些特征是重要的仍然不清楚。一种可能性是，最大的好处是由白天最明显的特征提供的，因此最有可能被人们体验到。我们证明，五个邻里的自然特征测试，植被覆盖和下午的鸟类丰度与抑郁症，焦虑症和压力的患病率较低呈正相关。此外，剂量反应模型显示了一个阈值反应，在该阈值反应下，心理健康问题的人群患病率显着低于社区植被覆盖的最低限度（抑郁症超过20%覆盖，焦虑超过30%覆盖，压力超过20%覆盖）。我们的研究结果表明，心理健康与人们实际体验的附近自然特征之间存在可量化的关联。
Experiences of nature provide many mental-health benefits, particularly for people living in urban areas. The natural characteristics of city residents' neighborhoods are likely to be crucial determinants of the daily nature dose that they receive; however, which characteristics are important remains unclear. One possibility is that the greatest benefits are provided by characteristics that are most visible during the day and so most likely to be experienced by people. We demonstrate that of five neighborhood nature characteristics tested, vegetation cover and afternoon bird abundances were positively associated with a lower prevalence of depression, anxiety, and stress. Furthermore, dose-response modeling shows a threshold response at which the population prevalence of mental-health issues is significantly lower beyond minimum limits of neighborhood vegetation cover (depression more than 20% cover, anxiety more than 30% cover, stress more than 20% cover). Our findings demonstrate quantifiable associations of mental health with the characteristics of nearby nature that people actually experience.
