With increasing attention on the health benefits of a forest environment, evidence-based research is required. This study aims to provide scientific evidence concerning the physiological and psychological effects of exposure to the forest environment on middle-aged hypertensive men. Twenty participants (58.0 ± 10.6 years) were instructed to sit on chairs and view the landscapes of forest and urban (as control) environments for 10 min. Heart rate variability (HRV) and heart rate were used to quantify physiological responses. The modified semantic differential method was used to determine psychological responses. Consequently, the high-frequency component of HRV, a marker of parasympathetic nervous activity that is enhanced in relaxing situations, was significantly higher and heart rate was significantly lower in participants viewing the forest area than in those viewing the urban area. The questionnaire results indicated that viewing the forest environment increased “comfortable,” “relaxed,” and “natural” feelings than viewing the urban environment. In conclusion, viewing forest landscape produces physiological and psychological relaxation effects on middle-aged hypertensive men. 相似文献

This study aims to verify the effects of nature sounds on attention, and physiological and psychological relaxation. Twenty-six university students (mean age: 21.5 ± 1.9 years) participated in this study, and the experiment was conducted with one person at a time. A mixed sound of valley water and birds in a forest environment was used as the nature sound, and a road traffic sound was used as the urban sound (control). The participants performed the following steps: (1) closed their eyes and rested for 1 min; (2) opened their eyes and completed attention tasks while hearing nature or urban sounds for 1 min; (3) closed their eyes again and rested while hearing the same sound for 1 min. We used Harris and Harris grid for the attention task. We measured the participants’ oxy-hemoglobin concentration, heart rate variability, and heart rate for physiological evaluation, and used semantic differential method, and profile of mood states for psychological evaluation. As a result, ① There was no significant difference in the results of the attention task; however, the scores were slightly higher when hearing nature sound. ② The oxy-hemoglobin concentration and heart rate was lower, and parasympathetic nerve activity was enhanced when hearing nature sound than when hearing urban sound. ③ Once participants heard nature sound, they felt more comfortable, relaxed, and natural, and the negative mood state was lower, while the positive mood state was higher than urban sound. This suggests that hearing nature sounds may be an effective way to relieve stress in everyday life. 相似文献

The impact of winter forest bathing on human psychological states was investigated in this study. Sixty-two participants were divided into two groups, each group was exposed to city forest or urban (control) environment for 15 minutes. The participants filled up four psychological questionnaires before and after exposure: the profile of mood states (POMS), the positive and negative affect schedule (PANAS), the subjective vitality scale (SVS), and restorative outcomes scale (ROS). The forest environment influenced the surveyed participants, causing a decrease in the negative subscales of POMS and an increase in the positive (vigor) subscale. Moreover, after exposure to the forest environment the participants had the highest scores of SVS, ROS, and a positive subscale of PANAS. This means that in conditions of Central Europe short winter interaction with forest had a substantial emotional, restorative, and vitalizing effect on the surveyed participants. 相似文献

In urban environments, green spaces have proven to act as ameliorating factors of some climatic features related to heat stress, reducing their effects and providing comfortable outdoor settings for people. In addition, green spaces have demonstrated greater capacity, compared with built-up areas, for promoting human health and well-being. In this paper, we present results of a study conducted in Italy and the UK with the general goal to contribute to the theoretical and empirical rationale for linking green spaces with well-being in urban environments. Specifically, the study focused on the physical and psychological benefits and the general well-being associated with the use of green spaces on people when heat stress episodes are more likely to occur. A questionnaire was set up and administered to users of selected green spaces in Italy and the UK (n=800). Results indicate that longer and frequent visits of green spaces generate significant improvements of the perceived benefits and well-being among users. These results are consistent with the idea that the use of green spaces could alleviate the perception of thermal discomfort during periods of heat stress. 相似文献

In a rehabilitation programme for people with stress disorder, a garden room can be an important ingredient. Stress disorder has been the most common cause of sick leave in Sweden since the 1990s. The study is about the therapeutic role of nature in the form of a garden, as participants experienced it during the recovery process. The research subjects were on sick leave due to stress related symptoms and took part in rehabilitation at the Alnarp Rehabilitation Garden in southern Sweden. The article is based on interviews with five participants who describe their experiences of garden therapy and what they perceive as essential for their recovery. The garden was associated with many positive experiences of interacting with people and greenery and perceived as a safe and useful arena in their recovery. The participants described how nature affords positive sensory experiences, physical and psychological well-being, but also how nature and the garden facilitate beneficial social interactions with other participants and caregivers. Importance was also allocated to the symbolism of nature as associated to one's own growth and the passing of time. They conceptualised the recovery process as initiated by more traditional forms of therapies but reinforced and consolidated by the access to nature and the garden rooms. In a dynamic psychological perspective on place, the study illustrates the potential role of using nature as a venue to facilitate self-regulation of physiological, psychological and social needs. 相似文献

Urban community parks, as widely distributed and frequently used small public urban green spaces, play an essential role in meeting the growing needs of residents for recovery. However, previous studies focus on the restorative benefits of nature and have rarely measured the restoration of winter scenes and artificial scenes. This paper selects a typical small community park in the winter city of China and studies how landscape elements affect restorative benefits through the setting of seasonal virtual scenes. Respondents were asked to rate natural, dynamic and seasonal virtual scenes in terms of sense of being away, extent, fascination, compatibility, and restorative potential. The results show plants with rich layers and large coverage areas have a significant positive impact on human perception of recovery, vitality facilities have no significant impact on perceived recovery, and the number of active people has a significant negative impact on perceived recovery. The plant landscape in winter and summer has the same effect on attention recovery, and seasonally induced changes in plant vision can enhance restorative benefits. 相似文献

Urban forests provide multiple ecosystem services for a range of user groups. However, teenagers are commonly underrepresented in studies about forest recreation and cultural ecosystem services. This paper examines teenagers' forest use and perception of ecosystem services compared to adult populations. We used an online panel survey to elicit motives for forest visits, frequency of visits, forest activities and constraints for visitation, and what ecosystem services participants expect from forests more generally. We then elicited perceived cultural ecosystem services of different forests by showing participants photographs of forest inventory plots for which we had detailed measures of physical forest characteristics to statistically assess the influence of forest characteristics and other parameters on perceived cultural ecosystem services. Results show that teenagers visit forests less often and also differ from adults in their preferences and activities, their motives for forest visits and reasons for not visiting forests. Teenagers exhibit more social and active forms of forest use, whereas adults use forests in more contemplative ways. Perception of cultural ecosystem services on forest photos was influenced by individual factors such as motives for forest visits, preferences, importance of forest during childhood and socio-demographic factors. Environment- and forest-related factors such as forest type, stand structure and single elements such as root plates and stumps had an influence on ecosystem service perception. We conclude that teenagers have different needs than adults concerning the provision of cultural ecosystem services from forests and therefore should be considered as a user group of its own in the management of recreational forests. 相似文献

The purpose of the study was to investigate whether deliberate psychological tasks, intended to focus people’s attention on the interaction between themselves and natural surroundings, are linked with mood enhancement and self-reported restoration. In four European countries (Finland, France, Luxembourg, Sweden), we surveyed the experiences of volunteers (N = 299) who walked forest trails and carried out psychological tasks printed on the signposts along them. We investigated the similarities and differences of the trail experiences between the countries. Via multigroup modeling, we further examined the moderating role of nature-connectedness in relationships between satisfaction with the contents of the psychological tasks, mood enhancement, and restorative benefits. The results showed that, independent of age and gender, participants were more satisfied with the trails in Sweden and Luxembourg than in Finland. We detected no reliable differences in the restorative experiences or willingness to recommend the trail for others. In the moderation model, satisfaction with the signposts’ contents was connected to positive restorative change and mood enhancement. The moderator effects of nature-connectedness were not significant for either outcome. Thus, it is likely that satisfactory tasks will work equally well for people varying in nature-connectedness. This is a promising prospect for public health promotion. The fairly high level of nature-connectedness among the participants limits the generalizability of our results.Conclusions concerning the role of nature-connectedness should be made with caution due to the limited coverage of the concept in our measure. Future studies that separate the effect of psychological tasks from the restorative effects of nature itself are needed. 相似文献

Landscape planning and stress 总被引：3，自引：0，他引：3
Stress and stress-related illnesses, as reflected in medical records, have increased dramatically among adults and children in Western societies. A growing part of the budget for medical service in Sweden is used for individuals suffering from different stress-related illnesses such as burnout syndrome, insomnia and fatigue, depression, feelings of panic, etc. In this paper, we present results from a study in which 953 randomly selected individuals in nine Swedish cities answered a questionnaire about their health and their use of different urban open green spaces in and close to the city.The results indicate that city landscape planning may affect the health of town-dwellers. Statistically significant relationships were found between the use of urban open green spaces and self-reported experiences of stress – regardless of the informant's age, sex and socio-economic status. The results suggest that the more often a person visits urban open green spaces, the less often he or she will report stress-related illnesses. The same pattern is shown when time spent per week in urban open green spaces is measured.The distance to public urban open green spaces seems to be of decisive importance, as is access to a garden, in the form of a private garden or a green yard immediately adjacent to, for instance, an apartment building. People do not usually compensate for lack of green environments in their own residential area with more visits to public parks or urban forests.According to our results, laying out more green areas close to apartment houses, and making these areas more accessible, could make for more restorative environments. Outdoor areas that provide environments free from demands and stress, and that are available as part of everyday life, could have significant positive effects on the health of town-dwellers in Sweden. This may also apply to other Western societies. 相似文献

The replacement of natural environments with urban centers has increased the distance between people and nature, which generates an indifference and apathy towards natural areas. Such a phenomenon is particularly concerning when children are involved because they represent future generations. In the present study, we investigated the effect of ‘contact with a forest’ versus ‘no contact with a forest’ on the knowledge of biodiversity in children under the same socioeconomic and educational conditions. We recruited 267 children for our study; 110 children maintained contact with a forest, while 157 had no contact with an urban forest. We encouraged the children to express their knowledge of the natural environment through drawings. Our results showed that contact with a forest granted children greater knowledge of the native animals, but it did not seem to affect their knowledge of the vegetation. However, the lack of contact with a forest caused the children to give greater importance to human components as part of the forest. Proximity to a natural area, even in an urban environment, seems to help draw attention to its components and sets the groundwork for knowledge construction. Hence, it is highly important to encourage contact between urban children and natural environments, as it enables future generations to have a better connection with nature, which is essential for biodiversity conservation. 相似文献

Socioeconomic changes in many areas in the tropics have led to increasing urbanization, abandonment of agriculture, and forest
re-growth. Although these patterns are well documented, few studies have examined the drivers leading to landscape-level forest
recovery and the resulting spatial structure of secondary forests. Land cover transitions from agricultural lands to secondary
forest in the island of Puerto Rico have been ongoing since the 1940s. This study is a glimpse into this landscape level trend
from 1991 to 2000. First, we relied on Landsat images to characterize changes in the landscape structure for forest, urban,
and agricultural land classes. We found that although forest cover has increased in this period, forest has become increasingly
fragmented while the area of urban cover has spread faster and become more clustered. Second, we used logistic regression
to assess the relationship between the transition to forest and 21 biophysical, socioeconomic, and landscape variables. We
found that the percentage of forest cover within a 100 m radius of a point, distance to primary roads and nature reserves,
slope, and aspect are the most important predictors of forest recovery. The resulting model predicts the spatial pattern of
forest recovery with accuracy (AUC-ROC = 0.798). Together, our results suggest that forest recovery in Puerto Rico has slowed
down and that increasing pressure from urbanization may be critical in determining future landscape level forest recovery.
These results are relevant to other areas in the tropics that are undergoing rapid economic development. 相似文献

BackgroundRegular physical activity can help prevent noncommunicable diseases, and improve mental health, quality of life, and well-being. ‘Green exercise’ is physical activity performed in natural settings such as parks and open green spaces. It is important to understand whether green exercise can provide additional physiological benefits over and above those of physical activity in urban environments. This pilot study compared the acute effects of a 30-min walk in a green environment to a 30-min walk in urban streets on adults’ heart rate and salivary cortisol.MethodsUsing a 2 × 2 randomised cross-over design, groups of 2–5 adults completed two experimental sessions involving a randomly assigned walk in an urban or a green environment. Heart rate and salivary cortisol were collected at regular intervals before, during, and in the 1.5 h following the walks and were compared within and between participants. Peak height, reactivity, area under the curve with respect to ground (AUCg) and area under the curve with respect to increase (AUCi), were also calculated for heart rate and cortisol and compared between walking conditions.ResultsThe sample included 20 participants (50 % female, mean =24.4 ± 4.0 years). Changes in heart rate (Condition × Time: F[5.8, 103.8]=1.67, p = 0.140) or cortisol (Condition × Time: F[2.6, 49.5]=0.81, p = 0.482) in response to walking were not statistically significantly different between the urban and green walking conditions. There were also no statistically significant differences in heart rate or salivary cortisol for the peak height of the response, reactivity, or AUCi or AUCg between the urban and green walking conditions.ConclusionOur findings suggest that physical exertion is the main driver of the acute physiological response to walking. Notwithstanding psychological benefits reported elsewhere, the acute physiological response to walking was not influenced by the green compared with the urban environment in the current study. Further research is warranted to understand the longer-term effects of regular green exercise. 相似文献

In modern society stress is a major problem, causing lack of mental and social well-being as well as potential vulnerability to problems at work. Previous studies have found natural environments to be relaxing. In this intervention study, performed in Northern Sweden, the hypothesis was that an outdoor forest environment would be more relaxing than an indoor handicraft environment. Forty-six participants with high stress levels (PSQ ≥ 0.4) (33 women, 13 men, average age 48 years) were randomly assigned to visit either the forest environment (n = 27) or the handicraft environment (n = 19). The participants visited their assigned environment twice a week during three months, either in autumn or spring. During each visit they spent two hours performing, simple and undemanding activities. Psychological health outcomes were measured by the questionnaires CIS, PSQ, SCQ, SMBQ, SF-36 before and after the three months interventions. Sleeping patterns were monitored by an Actiwatch and sleep diary. The participants’ mood before and after each visit were estimated by a questionnaire. The results show that the participants’ health had improved after the interventions in both the forest and handicraft environments. The sleep latency increased slightly among participants in the handicraft environment. For participants in both environments the levels of fatigue, stress and burnout were all lower. They felt less limitation due to physical problems and did not feel so tired. Also their mental health had improved. From start to end of a visit to either environments the participants’ mood was improved, and they felt more relaxed, alert, happy, harmonious, peaceful and clearheaded. Over time during the intervention, they also felt significantly more clearheaded. We conclude that the health of all participants improved, irrespective of the environment visited. 相似文献

Urban forests provide multiple ecosystem services for city dwellers, amongst which improving public health via mitigating mental stresses and providing attractive spaces for diverse physical activities has attracted increasing attention from scholars and policy makers within the context of the ongoing COVID-19 pandemic as well as urgently-needed post-pandemic urban transformation towards healthy cities. This short communication summarizes existing empirical evidence pertinent to the linkage between urban forests and public health maintenance and improvement, highlights three underlying mechanisms, i.e., physiological, psychological, and immunological pathways, and outlines practical implications for the establishment and management of urban forests as a strategy for planning healthy cities. 相似文献

Although many studies have explored the correlations between mobility intervention policies and park use during COVID-19, only a few have used causal inference approaches to assessing the policy’s treatment effects and how such effects vary across park features and surrounding built environments. In this study, we develop an interrupted time-series quasi-experimental design based on three-month mobile phone big data to infer the causal effects of mobility intervention policies on park visits in Shenzhen, including the first-level response (FLR) and return-to-work (RTW) order. The results show that the FLR caused an abrupt decline of 2.21 daily visits per park, with a gradual reduction rate of 0.54 per day, whereas the RTW order helped recover park visits with an immediate increase of 2.20 daily visits and a gradual growth rate of 0.94 visits per day. The results also show that the impact of COVID-19 on park visits exhibited social and spatial heterogeneities: the mobility-reduction effect was smaller in low-level parks (e.g., community-level parks) with small sizes but without sports facilities and water scenes, whereas parks surrounded by compact neighborhoods and land use were more impacted by the pandemic. These findings provide planners with important insights into resilient green space and sustainable neighborhood planning for the post-COVID era. 相似文献

An exploratory study of perceived safety in a neighborhood park using immersive virtual environments
Spatial configuration and physical characteristics of landscape features can strongly influence perceptions of fear and danger. This study examined how situational characteristics, particularly spatial enclosure shaped by surrounding vegetation, are related to perception of safety in a park setting. Study stimuli involved eight 360° immersive virtual environments (IVE) representing low, medium, and high spatial enclosure situations based on the degree of visual and locomotive permeability shaped by the physical arrangement of vegetation. Forty-eight students experienced the IVEs wearing a head mounted display device and then indicated on a 5-point scale how safe they would feel walking alone in that location during the day. Immediately after rating each IVE, participants indicated the main reasons they would feel either safe or unsafe in that particular location. Analysis results indicated that subjects perceived high enclosure environments as significantly less safe than medium and low enclosure environments. In addition to enclosure formed by vegetation, attributes that contributed to perception of safety were presence of non-threatening people and paths. Results indicated that gender differences in perceived safety were significant for the high and medium enclosed environments only. Study findings would allow urban planners and park managers to better understand how the spatial characteristics of existing or planned urban greenspace are likely to influence perceived safety and consequently use patterns and the attainment of social and psychological benefits provided by urban parks. Such an understanding can help generate evidence-based guidelines for improving safety while preserving desired aesthetic and ecological properties of the landscape. 相似文献

We investigated the effects of urban environments on the chemical properties of forest soils in the metropolitan areas of
Baltimore, New York, and Budapest. We hypothesized that soils in forest patches in each city will exhibit changes in chemistry
corresponding to urbanization gradients, but more strongly with various urban metrics than distance to the urban core. Moreover,
differences in parent material and development patterns would differentially affect the soil chemical response in each metropolitan
area. Results showed that soil chemical properties varied with measures of urban land use in all three cities, including distance
to the urban core, which was an unexpected result. Moreover, the results showed that the spatial extent and amount of change
was greater in New York than in Baltimore and Budapest for those elements that showed a relationship to the urbanization gradient
(Pb, Cu, and to a lesser extent Ca). The spatial relationship of the soil chemical properties to distance varied from city
to city. In New York, concentrations of Pb, Cu, and Ca decreased to approximately background concentrations at 75 km from
the urban core. By contrast, concentrations of these elements decreased closer to the urban core in Baltimore and Budapest.
Moreover, a threshold was reached at about 75% urban land use above which concentrations of Pb and Cu increased by more than
twofold relative to concentrations below this threshold. Results of this study suggest that forest soils are responding to
urbanization gradients in all three cities, though characteristics of each city (spatial pattern of development, parent material,
and pollution sources) influenced the soil chemical response. 相似文献

The recovery of understory plants in recent forests is critical for evaluating the overall capacity of landscapes to maintain
plant biodiversity. Here we used a large data set of vegetation plots from the Flemish Forest Inventory in combination with
maps of forest history and soil-based Potential Natural Vegetation to evaluate regional differences in the rate of recovery
of understory plant diversity in three regions of Flanders, Belgium. We expressed the degree of recovery in recent forests
using the species richness of ancient forests as a reference point, and found strong differences among regions in the average
level of recovery. These differences appeared to be due to regional variation in average patch connectivity and age (ultimately
stemming from differences in land use history) and – to a lesser extent – environmental conditions. We also found an increase
in the proportional representation of vertebrate dispersed species and species with short-distance dispersal with increasing
levels of recovery. Our results highlight the potential drivers of inter-regional variation in the process of recovery of
plant diversity during restoration, and they emphasize the importance of historical and spatial context in the recovery process. 相似文献
