The global spread of COVID-19 has disrupted the normality of people’s daily lives, leading the population to social distancing and isolation. The closure of green areas also affected the well-being of the individual during the COVID-19 pandemic. Viewing flowers is expected to have similar positive effects to viewing natural scenery. Therefore, this study investigates how white, red, and yellow flower colors affect individuals’ psychological and physiological well-being. The experiment was conducted in an office-like setting with 50 participants. Participants looked at each flower color for 3 min. Electroencephalograms (EEGs), heart rate variability, and skin conductivity were measured to evaluate physiological responses along with both the semantic differential questionnaire (SD) and the Profile of Mood States (POMS) to assess psychological responses. EEGs showed that the mean values of alpha relative power in the prefrontal lobe were significantly higher when viewing yellow and red flowers vs. white flowers. Furthermore, heart rate variability revealed that viewing yellow and red flowers increased parasympathetic nerve activity significantly. After viewing the yellow and red flowers, the average results for each subscale of the POMS questionnaire improved. The vigor (V) subscale and overall mood status values were significantly improved. The results of the SD method revealed that viewing yellow and red flowers resulted in a significantly higher sense of relaxation, cheerfulness, and comfort than viewing white flowers.
An important role of roadside trees in alleviation impacts of heat and microclimate at highly stressed urban areas. Nonetheless, it has not been completely explored the psychological responses to urban streets surrounded by trees. Fifty-five subjects visited two types of roads: a control road was selected by surrounded buildings and another road surrounded by with Londonplane trees. The results show that the short-walk in roads surrounded by trees with vegetation may be effective in reducing negative symptoms of stress, and their recovery results and vitality were significantly increased. The evidence suggests that urban street trees could be an important public health resource for reduced human stress and had a significant cooling and humidifying mitigating effect on microclimate.
The development of urban green space is closely related to the health of human settlements. As an important part of urban green space system, urban roadside trees play an important role in improving urban ecological environment, residents' physical and mental health and quality of life. How to design the green space of urban streets with the orientation of health, to reduce the negative impact on the modern urban environment and keep the urban residents in physical and mental health is the urgent demand for healthy living environment in the city. 55 participants visited three types of urban roads: a road where buildings are concentrated was selected as a control road, and two roads surrounded by Sakura and Metasequoia trees respectively. The results showed that after walking along the Metasequoia (full shade) and Sakura (semi-shade) roads after 15mins, the participants' negative mental states such as tension, fatigue, confusion and anxiety were significantly reduced compared with the control roads, and their recovery results and vitality were increased. Therefore, in order to resource for the pressure and promote the health of urban residents, the planning and design should take into account the age factor, and give priority to the trees with rich vegetation.
城市行道树冠层对不同年龄人群心理健康的影响研究谢军芳 1 , 刘滨谊 1,* 1 建筑与城市规划学院景观系, 同济大学, 上海, 中国 *通讯作者 关键词:城市化,行道树,冠层遮荫,人居环境,心理健康 摘要:城市绿地空间的发展与人居健康密切相关,城市行道树作为城市绿地系统的重要组成部 分,在改善城市生态环境、增进居民身心健康和提高居民生活质量等方面具有重要作用。如何 以健康为导向进行城市街道的绿地空间设计,从而减轻现代城市环境承受的负面影响,使城市 居民保持良好的身心健康状况,是城市化社会中人类对健康人居环境的迫切需求。为了探索人 类对不同植被覆盖城市行道树的心理反应机制,研究了 55 名青年及中老年被试者沿着 3 种典 型城市道路(建筑物集中的道路作为对照路,另外两条道路分别环绕樱花树和水杉)步行 15 分钟后的心理状态。结果显示,被试者沿水杉路(全遮荫)、樱花路(半遮荫)短时行走后, 其紧张感、疲劳、困惑和焦虑等负面心理状态比对照路行走后显著降低,其恢复结果和活力升 高。因此,为了缓解压力和促进城市居民健康, 在进行规划设计时应考虑年龄因素,并优先考 虑植被丰富的树木。 1. 引言 随着经济和社会的不断发展,世界城市居民人口数量急剧增加。快速的城市化进程不仅引
The present review aims at understanding urban policy frameworks and context on China’s urban green space system at national level. In order to allow critical reflection on the strengths and weaknesses of urban planning policy and green space system. The rationale of this review is to enhance the overall quality of urban environments and to promote urban sustainability, health and improved living. There is a general convergence of policy trajectories indicating that policymakers, planners and professionals have recognized the mutual interdependence of the relationship between green space and the quality and quantity of housing provision. Overall, improvements have been made to better integrate with urban green space and long-term urban management as a whole to create quality living environments. However, both national policy and regulations lack specification on the quality and quantity of green space and are yet standardized, there is not yet useful guidance or criteria on best practice for design for green spaces, and little reference to green space governance or leadership, management norms and abilities.
In this paper, I discuss historic and contemporary relationships between landscape design, housing and everyday uses of green space in urban China. By drawing together writing focused on theorizing nature and everyday life, I offer critical insights into urban political, economic, social and cultural change in Chinese cities. The paper begins with a review of religious philosophies and cultural traditions relating to the development of Chinese gardens and then discusses the impact of the introduction of 'western' style public parks alongside the emergence of modern urban planning and design. The second half of the paper traces how changing notions of nature and everyday life can be mapped onto housing development and associated urban social and spatial inequalities. In conclusion, I highlight how critical insights at the intersection of thinking on nature and everyday life can inform socially progressive urban development, planning and policy.
