城市发展项目可能耗资巨大，并对健康产生影响。因此，对城市规划采取循证方法至关重要。然而，城市绿色空间的物理和非物理健康效益的证据是不清楚的。方法文献检索的学术和灰色文献进行研究和评论的健康影响的绿色空间。对发现的文章进行相关性评估、批判性审查并相应评级。他们的研究结果，然后按主题categorized.Results有微弱的证据之间的联系，身体，心理健康和福祉，和城市绿色空间。环境因素，如绿色空间的质量和可达性，影响其用于体育活动。用户决定因素，如年龄、性别、种族和安全感，也很重要。然而，许多研究受到研究设计不佳，未能排除混杂，偏见或反向因果关系和统计associations.Conclusion大多数研究报告的结果，普遍支持的观点，绿色空间有一个有益的健康效果。建立因果关系是困难的，因为关系是复杂的。因此，简单的城市干预措施可能无法解决景观重新设计无法补救的城市健康的根本决定因素。
Background Urban development projects can be costly and have health impacts. An evidence-based approach to urban planning is therefore essential. However, the evidence for physical and non-physical health benefits of urban green space is unclear.Methods A literature search of academic and grey literature was conducted for studies and reviews of the health effects of green space. Articles found were appraised for their relevance, critically reviewed and graded accordingly. Their findings were then thematically categorized.Results There is weak evidence for the links between physical, mental health and well-being, and urban green space. Environmental factors such as the quality and accessibility of green space affects its use for physical activity. User determinants, such as age, gender, ethnicity and the perception of safety, are also important. However, many studies were limited by poor study design, failure to exclude confounding, bias or reverse causality and weak statistical associations.Conclusion Most studies reported findings that generally supported the view that green space have a beneficial health effect. Establishing a causal relationship is difficult, as the relationship is complex. Simplistic urban interventions may therefore fail to address the underlying determinants of urban health that are not remediable by landscape redesign.
