The presence of green spaces has been associated with improved physical health and better mental health and wellbeing. In contrast, the presence of gray features including build-up areas might have a negative impact on the health and wellbeing of citizens. To date, the available evidence on the health effects of green and gray spaces have mainly relied on 2-dimensional (2D) indicators of these spaces such as land use maps or, more recently, satellite derived indices (e.g., green space indices such as normalized difference vegetation index (NDVI) or gray space indices such as imperviousness). Although they are acceptable proxies of these exposures, 2D indicators could have inaccuracies when characterizing diverse set of vegetation types in combination with different types of gray spaces, which is typical of urban environments. To overcome this gap, we developed a set of three-dimensional (3D) indicators derived mainly from airborne LiDAR (Light Detection and Ranging) acquired in 2008 and 2010 over the metropolitan area of Rome (Italy). In particular, we extracted volume of green features such as shrubs and trees (Green volume [m3/ha]), volume of buildings (Gray volume[m3/ha]), a novel index called Normalized Difference Green-Gray Volume index (NDGG) as well as indicators of the tree count. We compared the 3D indicators with two widely used 2D indicators for characterizing green and gray spaces (i.e., NDVI and imperviousness) in different buffers around 79140 address points in the city. For the green indicators, we found that the Pearson correlations between NDVI and Green Volume were 0.47 (50 m buffer) and 0.33 (300 m buffer) while the correlations between NDVI and number of trees were 0.56 (50 m buffer) and 0.58 (300 m buffer). For gray indicators, the correlations between imperviousness and gray volume were 0.62 (50 m buffer) and 0.79 (300 m buffer). For NDGG, the correlations were higher with both NDVI (0.76 and 0.83 for 50 m and 300 m buffers) and imperviousness (−0.75 and −0.83 for 50 m and 300 m buffers). Our results showed that the use of 3D indicators can have potential benefits, especially regarding green features which can be highly heterogeneous in complex urban landscapes such as the city of Rome. 相似文献

Increasing urbanization, impervious space, and the impact of climate change are threatening the future of cities. Nature-based solutions, specifically urban green infrastructures, are seen as a sustainable strategy to increase resilience against extreme weather events, including the escalating occurrence of stormwater runoff flooding. Consequently, urban planners and decision-makers have pushed their efforts toward implementing green infrastructure solutions to reduce the impact of stormwater floods. Among others, green roofs help store water and decrease stormwater runoff impacts on a local scale. This research aims to investigate the effect of surface permeability and green roof implementation on reducing stormwater flooding and subsequently provide urban planners with evidence-based geospatial planning recommendations to improve urban resilience in Helsinki. First, we modeled the current impact of stormwater flooding using the Arc-Malstrom model in Helsinki. The model was used to identify districts under high stormwater flood risk. Then, we zoomed in to a focus area and tested a combination of scenarios representing four levels of green roof implementation, two levels of green roof infiltration rates under 40-, 60-, 80-, 100 mm precipitation events on the available rooftops. We utilized open geographic data and geospatial data science principles implemented in the GIS environment to conduct this study. Our results showed that low-level implementation of green roofs with low retention rates reduces the average flood depth by only 1 %. In contrast, the maximum green roof scenario decreased most of the average flood depth (13 %) and reduced the number of vulnerable sites. The proposed methodology can be used for other cities to develop evidence-based plans for green roof implementations. 相似文献

Spatial impacts of multimodal accessibility to green spaces on housing price in Cook County,Illinois
This study explores the impacts of multimodal accessibility to green space on housing price. Quantifying the benefits of green space accessibility is important for supporting green infrastructure planning and guiding land use development. In this study, we calculate multimodal travel times (walking and driving) from each residential property in Cook County (Chicago metro), Illinois to each articulated (public or significant private) green space. A gravity-model based method is used to compute accessibility (by travel mode), which considers the access to multiple green spaces and weights prioritization. Green spaces are divided into seven categories depending on their type and size to differentiate their potential benefits. Hedonic models using housing structural features, locational attributes, socio-economic factors and green space accessibility as explanatory variables, are used to evaluate housing price (using housing transactions records from 2010 sales in the county). The spatial effects of green space accessibilities on housing prices are explored by an Ordinary Least Squares (OLS) regression, with and without fixed locational effects, and a Geographically Weighted Regression (GWR). Results show walking and driving accessibility to all sizes of recreational, medium conversational and private green spaces present positive impacts on housing price, with some negative impacts to larger (and smaller) conservation areas. The relationship also exhibits different heterogeneous spatial pattern over the study area between walking and driving accessibility to green space, possibly related to economic variation. 相似文献

Although there is a common trend towards increasing green space in modern cities, urban green spaces provide not only ecosystem services but also disservices for urban dwellers. However, the relationship between urban greenness and ecosystem disservices has been poorly examined. We aimed to understand the effect of greenness level on the abundance and species composition of hornets – critical pests in Japan and to identify the best spatial scale for estimating their abundance with reference to greenness levels. We used a dataset that contained eight years of abundance data for four hornet species at 11 sites in Nagoya city. The levels of greenness around the hornet sampling points were measured using averages from the Normalized Difference Vegetation Index (NDVI) with radiuses of 0.1–10.0 km. We analysed the relationship between abundance and species composition of hornets and NDVI at different spatial scales using generalized linear mixed models. Higher NDVI values positively affected the abundance of all the hornet species except Vespa analis. The abundances were estimated most effectively using the NDVI average with a 1–2 km radius for all species. The species composition of hornets drastically changed along the gradient of NDVI values; V. mandarinia was dominant in greener areas (over 0.2–0.3 NDVI average with a 2 km radius) and V. analis in less green areas (below 0.2–0.3 NDVI average). Our study showed that the abundance and species composition of hornets were both strongly associated with the level of urban greenness. This suggests that increases in the greenness of urban areas can increase hornet abundance and alter the species composition of hornets; a more aggressive species, V. mandarinia, may also increase in urban areas, although V. analis is currently the most critical species according to regional consultants. Balancing ecosystem services and disservices has become crucial for the planning and management of green spaces, particularly when urban green space increases. We also demonstrate how human tolerance towards wildlife may have to be improved in order to live in greener environment where wildlife can be expected. 相似文献

There is increasing awareness of the benefits of campus green space in promoting student's health. However, information on how campus green spaces benefit students’ health is insufficient or limited to guide the planning or management process. As a result, the present study collected 897 valid responses to examine the differences in campus green space usage patterns among students with varying individual characteristics and to assess the interrelationships between students’ socio-demographic characteristics, perceived naturalness, patterns of use, and self-rated restoration and health using a structural equation model. The findings indicated that there were gender disparities in the presence of companions and frequency of use of campus green space, as well as discipline differences in companion presence. Additionally, gender, age, and discipline had distinct associations with perceived naturalness, patterns of use and self-rated restoration and health. Perceived naturalness positively contribute to patterns of use and self-rated restoration and health, while the frequency of use positively contributed to self-rated restoration and health. Moreover, students’ perceived health can be improved in part through the mediating effect of the self-rated restoration. The study findings demonstrated how campus green spaces benefit students’ health and provided valuable information for campus green space managers and designers. Therefore, we propose that presenting diverse natural elements, manipulating them in natural forms, providing feelings of wildness or friendliness, and eatablishing vast, high-quality, and diverse green spaces to promote students’ health. 相似文献

Green Infrastructure (GI) connects different types of green features via various scales, thereby supporting urban biodiversity and service provision. This study presents a methodology capable of identifying multiple functions to assess GI in less-developed countries, where such methodologies are lacking. GI was assessed based on a high-resolution land use classification using both landscape metrics and spatial data within an urbanized region of San José, Costa Rica, at different scales (watershed, neighbourhood, object). Results showed highly fragmented green spaces (often <10 ha), typically unable to support high levels of biodiversity, along with a low amount of green space per inhabitant (<7.4 m²) within the watershed. Substantially higher tree cover (x6) and tree density (x5) were found in the greenest neighbourhood in comparison to the least green neighbourhood. Potential areas for new GI in the form of green roofs (4.03 ha), permeable pavement (27.3), and potential retention areas (85.3) were determined. Several green spaces (n = 11) were identified as promising GI sites with the potential to increase provision (18.6 m²/inhabitant). The adopted methodology demonstrates the potential of GI for increasing recreational green space access, runoff reduction, and flood retentions while supporting biodiversity, validating its utility in guiding decision-making and policy generation. 相似文献

City place branding, an entrepreneurial urban development scheme, aims to differentiate cities from their national and international competitors based on strengths and competitive advantage. One such strength is quality urban green space which has been shown to make cities more attractive and liveable places, drawing people and investments to urban centres. Applying a place branding approach, this paper presents the results of a survey of Danish municipalities and their place branding in terms of crafting green city, or environmentally sustainable, profiles. Based on survey responses from both municipal green space and communication staff, an overview is presented of the status of ‘green’ municipal place branding, with emphasis on branding through green spaces such as parks. Findings show that green concepts such as environmentally sustainable policies as well as biophysical assets such as green spaces are not in focus in municipal place branding campaigns. Moreover, survey results demonstrate that creative professionals and local citizens are the main focus of those municipalities that are branding. There is great potential to emphasize green spaces in municipal placing branding campaigns building on partnerships with the private sector and citizen volunteers. 相似文献

The normalized difference vegetation index (NDVI) is often used as a marker of surrounding greenness in epidemiological studies aiming to evaluate the health effects of green space in urban settings. However, it is not clear the relationship between built environment characteristics, including green space, and NDVI. We aimed to evaluate the relationship between built environment characteristics, based on land-use and land-cover maps, and NDVI as a marker of surrounding greenness in the city of Barcelona. We used data from an already existing cohort of pregnant women in Barcelona (N = 8402). NDVI was derived and averaged within buffers of 100 m and 300 m for each participant, and categories of the built environment (m2) were derived from land-use and land-cover maps of Barcelona. We conducted ANOVA models to calculate the contribution (R2) of each land-use (or land-cover) category. The variability in NDVI in Barcelona was mainly explained by urban green (R2 between 0.32 and 0.53) and natural green areas (R2 between 0.19 and 0.52), although for the latter less than 4% of the participants were exposed to this. Both land-use and land-cover maps explained NDVI at 300 m better (full models explaining 76% and 78%, respectively) than at 100 m buffers (full models explaining 55% and 54%, respectively). Results of the present study indicate that NDVI can be a useful greenness metric depending on the hypothesis and area of study. However, for certain sizes of study areas (buffers smaller than 100 m), NDVI might have a lower predictive value. Results of the present study should be replicated in studies from other cities with different urban characteristics and climate conditions. 相似文献

Global patterns in urban green space are strongly linked to human development and population density
Urban green space is important for alleviating high temperatures, pollution, and flooding in cities. Furthermore, it is becoming increasingly clear that urban green space is important for the mental and physical health of humans residing in cities and that urban green space may harbor unique biodiversity. Understanding the extent and drivers of urban green space is thus important. While urban green space has been mapped and studied at local to national scales, the global patterns and drivers of urban green space remain unknown, potentially hampering effective planning and allocation of resources toward reaching sustainable development goals. Here, we quantified the effect of environmental and socio-economic drivers (temperature, precipitation, human development, and population density) on urban green space globally by focusing on national capital cities. We used satellite imagery to map urban green space using two measures: the Normalized Difference Vegetation Index (NDVI), and the fractional cover of “green” land cover classes. NDVI is useful as it includes all vegetated surfaces, also small ones like gardens. However, land cover classes allow the exclusion of certain classes such as sports fields or cropland. We used boosted regression trees to show that climatic variables accounted for 75 % of the relative influence in urban green space, with a positive effect of precipitation and a negative effect of temperature. Importantly, socioeconomic variables accounted for 25 % of the influence on global urban green space, with a positive effect of human development index (HDI) and a negative effect of population density. HDI in relation to urban green space has not previously been tested globally, and our study shows that significantly affects urban greenspace. The results demonstrate that cities where development status is low and population densities are high, typically in the Global South, have less urban green space than the climate would predict. The results therefore suggest that human wellbeing does not only benefit directly from increasing human development and decreasing population densities in urban areas, but that these effects may be compounded by also improving nature’s contribution to people. 相似文献

Upon conclusion of the 30 years of civil conflict, Sri Lanka has entered into a new era of development. The beautification project of Colombo, Sri Lanka's commercial capital, can be considered as one of the most important projects among urban planning and restoration endeavours implemented throughout the island. In such urban development endeavour, green spaces planning play a crucial role in improving the environmental quality and standard of living of the residents. The objective of this study is to analyse the environmental quality in Colombo city based on green spaces and to provide appropriate recommendations to raise the environmental quality to international standards.In this study, green space areas were extracted from Thailand Earth Observation System (THEOS) satellite imagery using Normalized Difference Vegetation Index (NDVI). Extracted green space areas were further analysed quantitatively with air quality indicators and population density utilizing deductive indexing method at Grama Niladhari (GN) administrative division level to identify correlations of these factors. An environmental criticality map based on population density and percentage green spaces has been constructed to identify the areas with high criticality. The study revealed that 24% of the entire Colombo Municipal Council (CMC) area consists of green spaces. This study also revealed that 34 GN divisions out of 55 lack the minimum per capita green space recommended by World Health Organization for healthy living. Recommendations are presented regarding regions where new green spaces should be established to enhance the environmental standard of living up to international standards. 相似文献

A green city image of urban green spaces can provide positive benefits such as a stronger local identity, better socio-cultural ecosystem services, and ultimately the creation of a green city brand that attracts tourism and investment. This paper studies how urban green spaces can become a green brand that encompasses health-related elements. The health-related elements form part of the Green Brand Hexagon (GBH), as proposed in previous studies, and are tested with a sample of Hong Kong citizens (n = 301). The empirical results confirm the interrelation between these attributes and other GBH elements. The interrelation reveals a moderate association between the health-related elements and other green brand elements through regression model formulation. The findings suggest an extension of the health promotion value of the green spaces to the brand elements, focusing on the quality and the landscape aesthetic function of urban green spaces. While the effort of the public sector is highly recognized by the citizens, there should be an opportunity to thematize and brand the green city attributes to the public so that some of the problems of environmental gentrification and socio-environmental disconnection can be alleviated. 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

Urban green spaces have multiple benefits, yet their distribution is often uneven. Studies on green inequality frequently adopt static exposure assessments, disregarding exposure during individual mobility, resulting in potential biases known as the neighborhood effect bias. Neighborhood effect averaging problem (NEAP) shows that exposure based on personal mobility tends to be average for all participants, compared to exposure based on residence. This study examines the NEAP in the context of green inequality by considering the ornamental value of green space, specifically vegetation color diversity. Considering that vegetation color can attract attention and has health benefits, we hypothesized that it is a key feature related to NEAP, as residents may compensate for poor residential environment by accessing better environmental quality during daily mobility. To investigate this, we compared vegetation color exposure at community and individual levels, assessing whether NEAP exists. Our findings suggest that while communities with high economic levels had significantly higher exposure to vegetation color diversity, the exposure at the individual level tended to be average. Moreover, NEAP appears to be more of an issue when considering vegetation color diversity compared to a measure of total green space such as green view index. We acknowledge that due to the responsiveness of survey, the survey sample includes a higher proportion of the well-educated and employed individuals with potentially higher mobility, which may influence the results. Overall, this study provides supporting evidence for NEAP in the context of vegetation color exposure, but not green view index, emphasizing the critical role of enhancing the ornamental value of green space and strengthening the quality of green space in improving green inequality. 相似文献

Neighbourhood green space serves an important function for the urban population, and provides valuable ecosystem services for human well-being. In this article, we investigate the effects of naturalness, gender, and age on the activities, aesthetics, and self-reported well-being associated with urban green space. Our findings are based on a postal survey of residents living in close proximity to six different green spaces in the city of Gothenburg, Sweden. It is shown that higher perceived naturalness generated more activities and higher aesthetic values and self-reported well-being for residents living close to urban green spaces. The results also indicated that, regardless of the type of naturalness, women were more active in urban green spaces than were men. Women also saw greater aesthetic value in green spaces than men did, and had higher self-reported well-being associated with the urban green spaces. Finally, older residents were shown to participate in a greater number of nature-related activities than younger residents. Older residents also saw greater aesthetic values and had higher self-reported well-being associated with urban green spaces than younger people did. Seemingly, this poses a considerable planning challenge if areas of perceived naturalness are to be retained in cities, since the present trend is for reduced green spaces in cities and a ‘parkification’ of surviving natural areas. Further, because of the importance of perceived natural areas to the elderly, and in particularly women, distances to urban green areas should not be too great. 相似文献

Research on the health benefits of people’s long-term exposure to green space is lacking. Addressing this emerging topic, this study uncovers the association of green space types with a person’s healthy ageing score (HAS). We investigated the association with HAS by continuous exposure to various green space types for two years. Green space types include tree canopy, low-lying vegetation and open grass percentage within 1.6-km road network distance buffers at baseline and second follow-up. Healthy ageing outcomes included functional capacity, resilience and HAS while accounting for relocation. This is a longitudinal study of a cohort of 22,715 New South Wales residents aged over 45 who participated in the Sax Institute’s 45 and Up Study living in Sydney, Wollongong and Newcastle. Longitudinal models of healthy ageing on green space types were fit with controls for socioeconomic confounders. Women who did not relocate were associated with a lower functional capacity (β; 95%CI: −0.10; −0.15,−0.05) and higher resilience (0.11; 0.08, 0.14) compared to those who relocated. Apart from age, personal characteristics did not explain the variation in healthy ageing outcomes for participants who moved. For participants who did not relocate, 30% grass cover was associated with decreased functional capacity (−0.22; −0.41,−0.04) and HAS (−0.31; −0.56,−0.05). Also, 5–9% low-lying vegetation was associated with a decline in functional capacity (−0.09; −0.15, −0.03) and HAS (−0.09; −0.17, −0.01) of participants who stayed but improved resilience (0.28; 0.01, 0.55) of participants who relocated. Green space comprising over 30% tree cover appeared most beneficial for functional capacity (0.42; 0.31, 0.53), resilience (0.19; 0.13, 0.25) and HAS (0.60; 0.45, 0.75). For participants who relocated, over 30% tree canopy was associated with improved functional capacity (0.33; 0.54, 0.62) but not resilience or their HAS. Increased neighbourhood tree canopy supports healthy ageing. Older people should be supported to live in-home or move into nearby residential care and maintain regular contact with green spaces and trees, to maximise potential benefits for health and wellbeing. 相似文献

Green spaces are vital to the wellbeing of urban communities, largely due to the many Cultural Ecosystem Benefits (CEB) that nature contributes to outdoor recreation experiences (e.g., relaxation, inspiration, spiritual enrichment). To ensure equity in the distribution of CEB, however, we require a better understanding of how they relate to ethnicity. Through 100 in-situ semi-structured interviews with green space users in the Lee Valley Regional Park, London, UK, this research explored variation in outdoor recreational CEB based on i) ethnicity and ii) green space activity and attribute preferences. We compared green space preferences and CEB of Black, Asian and minority ethnic (BAME) and white users of two distinct types of urban green space: parks and more biodiverse Sites of Special Scientific Interest (SSSIs). Both white and BAME visitors to parks prioritized games/sports and built features whereas visitors to SSSIs more often undertook wildlife viewing and prioritized natural features. However, we found that white and BAME users of both types of urban green space derived similar CEB. Peace and relaxation were primary among these benefits, a result of both nature interaction and its contrast to the urban environment. These results demonstrate that nature does not have to be the focal point of outdoor recreation to contribute to wellbeing; rather, even as a backdrop to sports and cultural activities, nature provides similar benefits to green space users. To promote use of green space and foster intercultural understanding, we recommend integrating these shared benefits obtained from nature within marketing and engagement strategies. Future research is needed to explore CEB variation within and among distinct ethnic communities to fully capture the diversity of lived experiences. 相似文献

Effective urban planning, and urban green space management in particular, require proper data on urban green spaces. The potential of urban green spaces to provide benefits to urban inhabitants (ecosystem services) depends on whether they are managed as a comprehensive system of urban green infrastructure, or as isolated islands falling under the responsibility of different stakeholders. Meanwhile, different urban green space datasets are based on different definitions, data sources, sampling techniques, time periods and scales, which poses important challenges to urban green infrastructure planning, management and research. Using the case study of Lodz, the third largest city in Poland, and an additional analysis of 17 other Polish cities, we compare data from five publicly available sources: 1) public statistics, 2) the national land surveying agency, 3) satellite imagery (Landsat data), 4) the Urban Atlas, 5) the Open Street Map. The results reveal large differences in the total amount of urban green spaces in the cities as depicted in different datasets. In Lodz, the narrowly interpreted public statistics data, which are aspatial, suggest that green spaces account for only 12.8% of city area, while the most comprehensive dataset from the national land surveying agency reveals the figure of 61.2%. The former dataset, which excludes many types of green spaces (such as arable land, private and informal green spaces), is still the most commonly used. The analysis of the 17 other cities confirms the same pattern. This results in broader institutional failures related to urban green infrastructure planning, management, and research, including a lack of awareness of green space quality (e.g. connectivity) and benefits (ecosystem services), and the related political disregard for urban green spaces. Our comparison suggests that a better understanding of green space data sources is necessary in urban planning, and especially when planning urban green infrastructure. 相似文献

Urban Heat Island (UHI) leads to increased energy consumption, aggravated pollution and threatened health of citizens. Urban green spaces mitigate UHI effects, however, it is still unclear how the green space characteristics and its surrounding environment affects the green space cool island (GCI). In this study, land surface temperature (LST) and land cover types within the outmost ring road of Shanghai, China were obtained from Landsat 8 data and high-resolution Google Earth data. The GCI effects were defined in three aspects: GCI range (GR), amplitude of temperature drop (TA) and temperature gradient (TG). Pearson correlation analysis was processed to get the relationship between the aspects and impact factors. The results indicated that the GCI principle could be explained by the thermal conduct theory. The efficient methods to decrease LST of green spaces include increasing green space area while staying below the threshold, adding complexity of green space shape, decreasing impervious surfaces and enlarging the area of water bodies. For the surrounding environment of the green spaces, increasing vegetation and water body fractions or decreasing impervious surfaces will help to strengthen GCI effects. The findings can help urban planners to understand GCI formation and design cool green spaces to mitigate UHI effects. 相似文献

This paper examines the relation between visitor behaviour and certain features of a number of major green spaces in the city of Granada, south-eastern Spain, focussing on key urban, ecological and landscape-related issues. Information on user profiles and numbers, the various uses made of these areas, their design, plant species richness and local urban and sociological background, was collected by means of in situ observation in a total of ten urban green spaces with surface areas of over 5000 m2. Findings indicated that these spaces were used largely for purposes directly related to well-being: recreational and sporting activities, socialising, or simply relaxing. Interestingly, the most common activities in each space were governed by features intrinsic to the space itself: accessibility, design, maintenance and plant richness and distribution, all of which affected the health-related attributes and aesthetic value of the space. The study also highlighted a number of serious deficiencies in certain green spaces, which will need to be addressed in future action plans and replanning projects as an essential step in ensuring that they meet the real needs and expectations of the target population. The information provided by this research may prove particularly valuable for improving the systemic functions of green spaces in Mediterranean cities sharing similar bioclimatic and sociological features, and for ensuring that they fulfil the role assigned to green spaces in sustainable cities. 相似文献
