Many cross-sectional studies have supported the health benefits of urban greenways. However, the causal relationship between urban greenway intervention and residents’ physical and mental health remains unclear. Furthermore, the potential dose-response effect by distance to a greenway intervention remains unknown. This study explored the impact of a large-scale urban greenway intervention (construction of a 102-km-long East Lake Greenway in Wuhan, China) on the health outcomes of residents by using a natural experimental research design. We collected data before and after the intervention (in 2016 and 2019, respectively) from 1,020 participants living within a 5-km street-network distance from the entrances of this greenway. The average age of the participants was approximately 50, and most of them were married. More than half of the participants were female, currently employed, and had received a college education or above. Mixed-effects difference-in-difference (DID) models were used while controlling for individual and neighbourhood covariates. The results showed that the East Lake Greenway had a positive effect on the self-reported mental health of residents who lived within 2 km, and these benefits decreased with distance. The physical health benefit was insignificant. To increase the health benefits of urban greenways, more effort should be made to improve the accessibility of greenways and the surrounding environment. We also advocate that future natural experiments should explore the distance-varying dose-response effect of green space interventions on health outcomes. 相似文献

As an important factor of scenic quality and biodiversity along a greenway, landscape diversity has yet to receive as much attention as it deserves. In the practice of greenway alignment planning, it usually gives way to the primary consideration of land suitability. In this article, we aim to make up this missing link. Upon the new concepts and measurement of linear landscape diversity and cellular landscape diversity, we proposed greenway potential index incorporating land suitability and landscape diversity. The greenway potential index was combined with connectivity analysis to connect path between a future greenway’s origin and destination that meets both land suitability and landscape diversity requirements. Specially, with Wuchang (Wuhan City, China) as a case study area, we proposed three greenway alignment planning scenarios respectively according to the criteria of suitability, diversity and the synthesis of them. Markedly differences were revealed between the results of suitability greenways and diversity greenways. The results indicate that the tripartite model we proposed is capable of planning a connecting path between a future greenway’s origin and destination that not only meets land suitability requirements for greenway construction, but also incorporates as many landscape types of significant difference as possible. 相似文献

In the context of recent studies that have begun to establish a more quantifiable understanding of the use of urban greenways, this paper presents a preliminary investigation into the patterns in which a greenway is used and the mechanism behind the pattern of use of the greenway. Factors of the location, economic situation, environment and social background have been measured and analyzed in the use intensity model to interpret their impact on the use intensity of different sections of a greenway. The results suggest that use of the Waterfront Greenway in Guangzhou is highly impacted by population density, employment density, nearby service provision and the connectivity of the greenway to other parts of the city. In this case, the use intensity model with indicators such as location, economic, environmental and social factors has been shown to be applicable to the evaluation of the use of the greenways. Results from the case study suggest that providing greenways close to the residential zones, employment centers and key public services such as hospitals and schools will increase greenway use. The surrounding network system of a greenway must be carefully considered and designed to improve the linking of the greenway to other parts of the city, to increase the number of potential visitors to the greenway. 相似文献

With increased demand for outdoor recreational spaces, it is imperative to understand the experience of recreational hikers. This study explored users’ recreation choices and behavior-based setting preferences for certain trails in one forest park. Using on-site intercept surveys, a total of 1019 samples were collected from users of hiking trails and greenways in Purple Mountain Forest Park, Nanjing, China. The results from multiple regressions revealed that visitors’ recreation choices for trail settings, companions, and activities were associated with personal attributes, usage patterns, visitor motivations, and their preferences for the trail’s landscape attributes. The findings provide insights for the design and maintenance of trail settings in forest parks to satisfy the needs of various recreational hikers. 相似文献

Constructing and renovating urban parks is an effective strategy for high-density cities to satisfy residents’ needs for recreation in nature. Using Hong Kong as an example of a high-density city, the purpose of this study was to examine the associations of park and neighbourhood environments with park-based physical activity (PA) among children and examine the moderating effect of neighbourhood income in their relationships. A cross-sectional study was conducted in 32 urban parks in Hong Kong. Park-based PA and the park and neighbourhood environments were measured using systematic observation tools and the geographic information system. Neighbourhood income was extracted from the 2011 Hong Kong Population Census data on median household income. A total of 7,753 children were observed using urban parks for PA during the study. Children’s park-based PA was positively associated with the quality of supporting amenities, park safety, neighbourhood walkability, and neighbourhood quality, while the associations of park-based PA with the diversity of active facilities and park size were not significant. In addition, neighbourhood income moderated the associations of park-based PA with the diversity of active facilities, the quality of supporting amenities, neighbourhood walkability, and neighbourhood quality. These findings provide empirical evidence on the moderating role of neighbourhood socioeconomic status on the associations between park and neighbourhood environments and children’s park-based PA in a high-density city. With children’s needs for using parks for PA, our findings are beneficial for urban planners to renovate existing urban parks to enhance their utility for children living in high-density cities. 相似文献

Landscape perception and recreation needs in urban green space in Fuyang,Hangzhou, China 总被引：1，自引：0，他引：1
This study analyzes the landscape characteristics and the residents’ recreational activities in the urban green spaces in Fuyang, Hangzhou, China. It explores the correlation of the desire to be in close proximity to urban green space to engage in recreational activities (the need for recreation) related to residents’ demographic and socio-economic factors: gender, education, monthly income and dwelling location. Residents’ preferences for landscape elements and attributes of urban green space are examined using principal components analysis. In addition, regression analysis identifies that coherence and vegetation are the most relevant factors correlated with perceived overall recreational appropriateness of the three most frequently visited urban parks. The purpose of the study is to attempt to quantify people's recreation needs in urban green space; identify the landscape components in urban green space which can encourage more outdoor visits and/or greater recreational activities; and provide proposals and strategies on planning, management and conservation for recreation-oriented urban green space which will enhance people's enjoyment and wellbeing by improving landscape esthetic quality, recreational and ecological function. 相似文献

In Taiwan, urban parks have mainly cared for demands associated with recreational use and landscape aesthetics, while ecological functions have often been neglected. The purpose of this study was to examine park users’ awareness of the functions of urban parks, their attitudes toward Amsterdam Bos Park as well as their preferences and support for a sustainable forest park in Taipei metropolitan area. Moreover, the study intended to inform the decision makers in Taiwan about people's perception of urban parks. The findings suggested that participants were moderately aware of the economic benefit of urban parks, and highly aware of urban parks’ benefits regarding landscape beauty, social values, health and safety, and ecological conservation. Participants moderately agreed with the financial demand, and highly agreed with the development strategy, managerial operation, and design approach of the Bos Park. In addition, participants liked the concept of the Bos Park very much, and strongly supported the establishment of a sustainable forest park in Taipei metropolitan area. Based on the findings, recommendations were made to the Taipei City government for the decision-making in the development of a metropolitan park, as well as to landscape architects in the planning and design of urban parks. 相似文献

A person’s health and wellbeing are contingent on the amount of social support that they receive. Similarly, experiencing nature has been shown to improve people’s health and wellbeing. However, we do not know how relationships between social cohesion, nature experiences and nature connection could interrelate and vary across different types of urban green spaces, and in non-Westernised cultures. We conducted a study on 1249 residents in Singapore, a tropical city-state, and measured three dimensions of social cohesion (i.e. general social cohesion; trust and sense of community; and social interactions), various types of nature experiences (i.e. amount of green space around one’s residence; frequency and duration of urban green space visits; frequency and duration of visits to gardens), and three dimensions of one’s connection to nature: self-identity with nature, desire to experience nature, and environmental concern (using the nature relatedness scale). We found that people who strongly identify with nature, who enjoy being in nature, and who had more frequent gardens visits were more likely to have a stronger sense of social cohesion across two dimensions. However, those with stronger environmental concern reported an overall weaker sense of social cohesion, possibly due to the perception that society’s contributions to conserve environmental problems was insufficient. Further, people who gardened more frequently were also more likely to visit green spaces, self-identify with nature and exhibit a stronger desire to experience nature. We propose that strategies targeted at encouraging people to engage in nature-related, collaborative activities at the local community level, such as spending time in local gardens, will increase urban residents’ daily nature experiences and its associated benefits such as improving social cohesion. 相似文献

Small-size green spaces contain convenient service capabilities for urban residents and satisfy the daily needs of citizens for high-quality ecological products. A greenway is a kind of linear green space, which can create a beautiful and livable environment in a high-density urban area. This study explored whether the services provided by the greenway can meet the daily needs of urban residents for green space in Guangzhou, a mega city in south China. Based on the Analytic Hierarchy Process (AHP) method and the entropy weight (EW) method, both the coupling coordination degree model and spatial autocorrelation analysis were adopted to quantify and determine the coordination degree of greenway service supply and public demand in Guangzhou. The results showed that the comprehensive score of the greenway service supply (GSS) subsystem and the public demand (PD) subsystem in Guangzhou was 0.3865 ± 0.08 and 0.3778 ± 0.03 (mean±s.e., n = 11), respectively. The GSS subsystem score was slightly higher than that of PD subsystem (P > 0.05), indicating that the two subsystems had no significant differences. The supply and demand subsystem of ten districts (excluding Conghua) in Guangzhou achieved different levels of coordination, and the average coupling coordination degree was 0.5885, suggesting that the districts were barely balanced at the city level. The Moran's I value was 0.580, indicating that the coupling coordination degree had significant positive global spatial autocorrelation and showed a spatial agglomeration effect. Furthermore, the local Moran’s I spatial autocorrelation showed that three districts (i.e., Yuexiu, Haizhu and Liwan) formed a high supply-high demand cluster and a spatial difference was detected when coupling the GSS and PD in Guangzhou. Therefore, we proposed the differentiated optimization strategies based on the results of the coupling coordination degree and the development status of each district and the entire city. This knowledge can better guide the subsequent construction and development of greenway in Guangzhou and may be useful for adjacent cities in Asia-Pacific region. 相似文献

Urban green infrastructure provides city dwellers numerous benefits. Among them, cultural ecosystem services (CES) are distinguished by being easily perceived and essential for people and their well-being. However, not all CES are equally easy to perceive, resulting with some of the CES categories being weakly explored. Research on CES also rarely considers elements of urban green infrastructure other than parks and forests. Therefore, there is a lack of research on different components of urban green infrastructure, especially tree-based, perceived in relation to CES. This paper presents the results of focus group participatory mapping implemented with citizens in the city districts of Zagreb on the perception of five selected CES categories in various types of urban green infrastructure. Our results show that participants perceived 13 different types of tree-based urban green infrastructure as providers of CES. We also distinguish patterns in the perception of CES categories and their connection with types of tree-based urban green infrastructure. Tree lines are perceived as providers of aesthetical experiences. Furthermore, forests and park forests are perceived in relation to place attachment and recreational activities, while parks are versatile and provide all explored CES. Other types that emerged as important were greenways, greenery around residential buildings and educational institutions, which provokes rethinking of a careful planning of the entire repertoire of urban green infrastructure. 相似文献

Following the increasing public health concerns related to physical inactivity in the population, the relationship between outdoor recreation and public health has been increasingly acknowledged over the last decades. To improve public health, planners and policy-makers aim to provide good accessibility to recreational landscapes to facilitate outdoor recreational activity. At the same time, they are facing development pressure due to urban growth. In order for planners and policy-makers to secure people access to urban and near urban recreational areas, there is a need to map and measure access in a way that is adequate as a basis for decision-making in planning and design processes. Access is often defined as distance, or proximity, from residents’ homes to recreational areas. This paper explores different ways to map and measure distance to recreational areas, and aims to provide better decision support for planners and decision-makers. Moss municipality in Norway serves as a case study. We begin by addressing the meaning of the term ‘recreational landscape’ and how the choice of definition affects the results when mapping recreational areas. We also discuss who we are measuring distance for, and how different user groups will have different thresholds or critical distances affecting their frequency of visits to a recreational area. Last, we explore different methods for measuring distance within a GIS environment. The paper shows how the purpose of the analysis must be decisive when defining recreational landscapes and choosing methods for measuring access to recreational landscape, in order to provide valuable input to planners and policy-makers aiming at enhancing the possibility for outdoor recreation for people. 相似文献

The limited access to urban green spaces during the COVID-19 pandemic had a negative impact on the human-nature interaction in cities and human well-being. Number of visitors to green areas, initially declined due to imposed restrictions, was restored after they were lifted as established by several studies across the globe However, little is still known about changes in behavior and preferences of park visitors in the post-COVID time. In this study, we investigated spatial-temporal patterns of recreational activities in the three urban parks in Moscow (Russia) prior, during and after the COVID-19 lockdown (in 2019 and 2020). The selected parks represent two different types: a centrally located park with much infrastructure and open landscapes (Gorky Park) and parks located at the outskirts of the city center with a more forested landscape and little infrastructure (Timiryazevski and Sokolniki parks). Recreational activities were identified based on the analysis of social media photos using machine-learning algorithms. As expected, park closures during lockdown resulted in overall decrease in the number of taken photos. After the parks were re-opened, however, the number of photos did not grow immediately. The number of photos only restored after almost three months, and the visiting peak shifted to autumn. Differences between parks were related to the type of the park and its landscape structure. The lowest decrease in the number of photos was observed for the Timiryazevsky park – a semi-natural green area, while the centrally located Gorky Park was the most affected, likely due to the strictest control measures. In comparison to 2019, photos in 2020 were more evenly distributed across the area in all the three parks. Besides, ‘natural’ areas became the main attractors for the visitors - photos under ‘nature observation’ category became the most popular. Spatial distribution of the recreational activities in post-lockdown period was characterized by larger distances between photos, likely corresponding to the social distancing. COVID-19 pandemic highlighted the value of green areas for citizens, but also changed their recreational preferences and overall behavior in parks. The observed shift from high density of visitors around entertainments and attractions in 2019 to a more homogeneous and less dense distribution along the natural zones in 2020 reveals a new pattern in visitors behavior and preference, which shall be considered in spatial planning of the parks. Increasing availability of natural green areas and their integration in urban green infrastructures can become the most relevant policy to consider the crucial role of urban nature as a source of resilience in turbulent times. 相似文献

Given the importance of urban parks for recreation, it is critical to understand how they are used and perceived. Currently, relatively few studies have examined the public’s activities and preferences at the same time. Social media data are increasingly recognized as a promising data source to study these two aspects. However, little is known regarding the utility and representativeness of social media data for urban parks. In particular, a lack of understanding exists on the comparability of research results measured by bottom-up social media data and top-down official survey data in urban park studies. This research used social media data from Ctrip and Dianping and survey data from the local government agency with park visits statistics and park satisfaction surveys to understand the public’s visitation and satisfaction of 102 urban parks in central Shanghai. We first assessed the similarities between the social media data and survey data by correlation analysis. We then used the negative binomial regression model and beta regression model to examine the matches and mismatches of the different data sources in investigating factors influencing park visitation and park satisfaction. Our correlation results showed that the social media data significantly correlated with the survey data and that social media data performed better in more frequently visited parks. Our regression results showed that the water bodies, recreational facilities, and surrounding commercial facilities were the common influencing factors of park visitation and park satisfaction for all parks. While significant correlations were noticed between these two data sources, we found that the surrounding population density was negatively associated with park visitation measured by social media data but positively associated with park visitation measured by survey data. This study provides a comparative perspective to study park visitation and park satisfaction by combining social media data and official survey data. Clarifying the consistencies and inconsistencies between the social media data and official survey data is important because it could help us to understand the representativeness and potential biases of the social media data when used in visitation monitoring and satisfaction monitoring. 相似文献

The pursuit of urban agriculture as part of a city’s green infrastructure is often a challenge, particularly within compact cities, where there is a limited amount of space between buildings for urban farming and gardening. Instead, such high-rise urban developments present often under-utilized spaces on the vertical surfaces of buildings. A key unknown is the adequacy of light for plant growth. Many leafy vegetables that require high amounts of light form a significant proportion of the staple diet in many Asian countries. We report on the assessment of sunlight adequacy for growing leafy vegetables in a compact tropical city, based on the high-rise and high-density residential environment of Singapore. Leaf physiological traits of seven leafy vegetables were assessed and used to estimate plant light requirements. A survey of photosynthetically active radiation (PAR) along exposed corridors showed that the daily light integral (DLI) value ranged from 2 to 35 mol m−2 d−1 under relatively ideal weather conditions during days with abundant solar insolation, and façades that experienced a minimum of half-day direct insolation matched the light requirements of vegetables within the moderate to very high-light categories. With regard to the building form, PAR increased gradually with height, but remains highly influenced by façade orientation and configuration. Owing to the annual north–south oscillation of the sun’s path, reduced annual PAR variability and higher total annual PAR at façades, buildings with an east–west orientation will better support continuous vegetable cultivation, especially for basic building typologies without self-shading configurations. However, excessive PAR and temperatures during mid-day hours may hinder plant growth. By highlighting such patterns in levels of PAR, this study confirms the potential for high-rise and high-density conditions in the tropics to support farming using typically under-utilized vertical spaces of residential buildings. 相似文献

This paper explores how arborists negotiate their work environment, including the pressures of policies, the labour market, technologies, government regulations and lack thereof, and the non-human agencies with which they are confronted. The political climate surrounding urban forestry in Southern Ontario influences and governs operations and physical labour. There are many (f)actors and conditions (both external and internal) surrounding fieldwork in urban forestry and that these affect work and personal lives. The questions guiding this paper include: (a) How do various political and labour conditions impact arborists’ sense of pride, independence and skill?; (b) What are the social and labour divisions within the culture of arboriculture?; and (c) What is the lived experience of urban forest workers, their employment, and what is it like to be a frontline worker? This paper provides a closer look at licensing, work conditions, subcultures and social dynamics in urban arboriculture. Using accounts from semi-structured interviews with arborists across Southern Ontario and by examining field arborists’ activities, relationships with co-workers and working conditions through participant observation and ethnographic field notes, I explore and reveal how arborists feel about their working environment and the labour processes and people who oversee and surround them. Findings reveal that despite dehumanizing (f)actors within the field, there are elements of resistance and negotiation, and potential for an alternative future. 相似文献

The literature to date has mainly explored the impact on public mental health of green spaces around residential areas, large urban parks, family gardens, blue spaces, national parks, etc., while few studies have examined the association of Small Urban Green Spaces (SUGS) with public mental health. The role, function, and service radius of SUGS in urban people’s lives are quite different from those of general green spaces, and the relationship and mechanism linking general green spaces to mental health cannot be fully applied to small parks. This work was conducted to: 1) investigate the relationship between SUGS and mental health; 2) understand what factors affect mental health; 3) determine what kind of SUGS is more conducive to improving mental health. SUGS’ designs and physical characteristics were evaluated with the Natural Environment Scoring Tool (NEST) and user information for 10 SUGS (1–5 ha) in Shanghai in 2021 was collected via a questionnaire. We developed a multilevel model for exploring the factors affecting mental health from two aspects: the individual level and the park level. This study found that SUGS and mental health were positively associated. In addition to individual–level variables like income, marital status, social cohesion, and use frequency, park–level variables such as usability, aesthetics–natural features, and civilized environment are also conducive to improving mental health, while entertainment facilities in SUGS have a negative association with mental health. There was no evidence that visit frequency, stay time, social cohesion, or physical exercise act as a mediator between park features and mental health. This study provides empirical evidence for the positive correlation between SUGS and mental health and presents a means of promoting public mental health with efficient SUGS planning and management. 相似文献

Activities in natural environments greatly enhance human well-being and can support the integration of foreigners into a new country. This article explores how residents from different ethnic backgrounds in Turku, Finland appreciated and engaged with urban natural environments and how this engagement benefitted their well-being and, ultimately, their integration. Individuals enjoy activities in nature in particular ways, which may vary according to a person’s physical, social, and psychological characteristics. This is especially true for immigrants who apply traditions from their home countries to the ways in which they interact with their new environment and enjoy activities in nature. Three dimensions of nature experience—social, emotional, and normative—emerged from the research, which, in turn, supported well-being and different types of integration: interactive, identificational, and cognitive. We argue that because these dimensions are an integral part of a person’s identity and cultural background, familiarity with them may prove pivotal to constructing more welcoming and intercultural urban natural environments. Different approaches to engaging with nature should be considered in the design of urban environments and urban nature, as well as in integration programmes, to enhance the well-being and integration of foreign-background populations. 相似文献

Several studies from the Nordic countries show that cemeteries not only fulfil an important societal function as places for the disposal of bodily remains; they are also recreational landscapes that people visit to reflect, experience nature or perhaps go for a walk with the dog. In this comparative study, based on PPGIS data collected between 2018 and 2020 from residents in Copenhagen (Denmark) and Helsinki (Finland), we explored the extent to which residents use urban cemeteries as everyday recreational landscapes. We also assessed users’ characteristics and the values they attached to the cemeteries. The results show that several of Copenhagen’s cemeteries were actively used for recreation, while those in Helsinki were used much less frequently for this purpose. Of the total 7276 mapped visiting points in Copenhagen, 16.5% were located within cemeteries, compared with 1.9% of the 4298 mapped visiting points in Helsinki, hence conclusions from Helsinki should be drawn with caution. Physical activity and experiencing nature were the most common values attached to cemeteries in Copenhagen, whereas social interaction, spirituality and tranquillity were most common for Helsinki cemeteries. The results also revealed that younger Danes were particularly inclined to use cemeteries for social interactions, physical activity and spirituality and tranquillity. In the discussion, we elaborate on spatial differences between the cases, such as the availability of other green spaces, the size of cemeteries or people living in proximity to a cemetery, as well as on differences in policies and practices, including how Copenhagen stands out in actively promoting municipal cemeteries as recreational landscapes. 相似文献
