    查看更多>>摘要：? 2022 The AuthorsCriminal behavior has been traditionally linked to green space. However, studies on the relationship between green space and crime vary in their conclusions and even contradict each other. This variability is primarily attributed to the mixing-up of specific crimes and the less-explored influencing mechanisms. This study considers Toronto and focuses on a specific kind of crime, assault, for exploring whether green space influences the neighborhood assault rate. If so, then how does it affect the assault rate? By considering the neighborhood as the spatial analysis unit, the indicators of green space and its component structure (namely the composition of trees, shrubs, and grass) are included in the regression analysis model used in this study. The dual effect (both positive and negative) of walkability on crime is treated as the moderator in the regression model. Our analysis revealed that high percentages of green space, tree area, and grass area potentially inhibit assault occurrence, while the shrub area percentage has no statistically significant association with the assault rate. When walkability reaches a certain degree (84th or/and 50th percentiles in this study), it can enhance the inhibitory impact of the green space and its component structure (including trees, shrubs, and grass) on the assault rate. Comparatively, this reduction effect is more significant for green space composed of grass. Therefore, we can infer that increasing the percentage of trees and grass, while simultaneously improving walkability, can reduce residents’ risk of being assaulted at the neighborhood level.

    查看更多>>摘要：? 2021 Elsevier GmbHUrban greenspaces (UGS) are increasingly recognized for their potential to provide provisioning services to residents foraging for food and other plant materials. The alignment of tree species composition with foraging practices in cities, and the provisioning services harvesters derive, in UGS remains less well studied. To address this gap, we draw on existing tree species data and forager practices in the City of Philadelphia to estimate the alignment between tree species composition and foraging in the city. Our approach uses an existing forest inventory, an international online database of useful species, online information for residents about useful species found in the city, and novel data about forager practices. By considering these datasets in tandem, we are able to identify useful tree species, species likely of interest to foragers, and species actively foraged, and estimate the relative abundance of species in each category. Our results suggest that managers may be able to analyze proxy data, through use of online quality ratings, to rapidly identify and assess forager interest in species found in their urban forests.

    查看更多>>摘要：? 2022 Elsevier GmbHStudies on the linkages between nature exposure and physical activities often focus simply on the immediate vicinity of home locations, but path-based exercises, such as running and cycling, are continuous activities and cover a broad spatial extent. Thus, the traditional home buffer approach fails to acknowledge the settings where road running actually occurs. This study employed an activity path-based measure approach using public participation GIS (PPGIS) to investigate the associations between running satisfaction and nature exposure. The mapped routes (N=545) that included an assessment of satisfaction level were collected from 249 runners resided in the Helsinki Metropolitan Area, Finland. Logistic regression analyses revealed a positive association between running satisfaction and nature exposure, including eye-level greenness, top-down greenness and blue space density. Top-down greenness was assessed by Normalized Difference Vegetation Index (NDVI) and the eye-level greenness by Green View Index (GVI), the latter one of which uses a deep learning algorithm. Running environment was more satisfying in those routes with more public transport nodes. Other traffic-related factors breaking the momentum of runners such as traffic light density were inversely related to running satisfaction. Demographic characteristics such as education background also played a significant role in the perceived satisfaction with running routes. The positive impacts of nature exposure on running satisfaction further verify the linkages between landscape and public health.

    查看更多>>摘要：? 2022 Elsevier GmbHIn 2015, 17 Sustainable Development Goals were outlined within the 2030 Agenda by the United Nations. Objective 11.7 aims to provide universal access to safe, inclusive, and accessible green and public spaces, highlighting the strategic role of these areas in cities. In the international literature, the theory of Ecosystem Services (ESs) has been developed to raise public awareness of the need to preserve biodiversity, enhance community cohesion, civic identity, and quality of life. In this study, we explored the economic value of Singapore's Urban Green Infrastructures (UGI) by investigating the private condominium and apartment unit market through the Hedonic Pricing Method (HPM). The HPM was integrated with Geographic Information System (GIS) to spatialize housing units, measure the distance of different green spaces, and consider the dependence effects among housing unit transactions. The results highlighted a positive effect on values of the proximity to the natural green areas, as well as to the regional, city parks, and small nature areas. The annual benefits of UGIs on households within 800 m range from 10,305,275 USD for nature areas to 59,723,703 USD for the city parks and 74,011,689 USD for the regional parks. Estimates showed the small contribution of park connectors (PCN) and neighborhood parks. The HPM results are a useful aid to understanding the amenity value of UGIs. The modeling outcomes could be used to inform policymakers and municipal green managers about UGIs preservation and new allocation starting from households’ preferences.

    查看更多>>摘要：? 2022 The Author(s)This paper presents results from a container experiment and a real-scale study in road environments for evaluating the performance of soil mixtures and herbaceous perennials for use in rain gardens. The container experiment included 12 soil mixtures and 4 perennial species. The plants were exposed to three flooding events and one drought period, and their overall vitality was recorded after the floodings. The containers were stored outdoors the following winter and plant survival was observed in spring. Amsonia orientalis did not survive the winter after being exposed to flooding in the growing season and was replaced by Hosta ‘Francee’ in the real-scale study, which was established in Drammen (Norway) in a soil mixture based on optimisation of the best mixtures in the container experiment. Luzula sylvatica performed well in the container study and survived the winter; however, in the field study, individuals of this species that were located close to the road died due to de-icing salt. Eurybia divaricata showed some mortality in both studies, and total mortality occurred in individuals that were close to the road, due to de-icing salt. Hemerocallis cvv. performed well in both experiments and appeared to be useful in all rain garden positions in the cold climate road environment. H. ‘Francee’ developed well in the road environment, except when exposed to splashes of road water. The study highlights considerable differences between species’ adaption to roadside rain gardens in cold climates, and the need for further field investigations.

    查看更多>>摘要：? 2022 The Author(s)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.

    查看更多>>摘要：? 2022 Elsevier GmbHConstructing 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.

    查看更多>>摘要：? 2022Green exercise, the combination of exercise and nature exposure, is known to benefit physical and mental health. However, there is a lack of quantitative evidence to support the psychological advantage of green exercise over non-green exercise. Also, it is unclear if there are psychological differences between green exercise in wild environments and urban greenspaces. Therefore, we conducted a systematic literature search for outcomes concerning measures including the Profile of Mood States (POMS), Spielberger State-Trait Anxiety Inventory (STAI), Semantic Differential Method (SDM), Positive and Negative Affect Schedule (PANAS), and Restorative Outcome Scale (ROS). Nineteen studies with 1662 participants were included in a meta-analysis to examine the advantages of green exercise and compare them in the two types of natural environments. The results indicate that green exercise may lower negative affect, including anxiety, tension, anger, depression, and fatigue. Meanwhile, green exercise may lead to higher positive moods and emotions, including vigor, comfort, natural feeling, and relaxation. Nevertheless, the effect on overall positive affect was not statistically significant. The comparative results suggest that wild environments may be more effective than urban greenspaces in improving vigor and comfort during green exercise. In conclusion, our findings support the advantages of green exercise over non-green exercise, meanwhile implying potential psychological differences between exercises in wild environments and urban greenspaces. Due to the limited number of studies and high heterogeneities, a future review is warranted to re-examine the psychological benefits.

    Multifunctionality in practice: Measuring differences in urban woodland ecosystem properties via functional traits

    Cardou F.Aubin I.Shipley B.Lapointe M....
    10页
    查看更多>>摘要：? 2021The ability of urban woodlands to regenerate and provide ecosystem services depends on the maintenance of a range of ecosystem functions and processes (i.e. multifunctionality). Many conservation decisions are made by local land stewards and rely on taxonomic characterization of woodlands to infer ecosystem properties, but there is reason to doubt this approach. Can functional traits provide better information on ecosystem multifunctionality? We compare three methods for capturing differences in urban woodland multifunctionality. We ask whether differences in (1) species composition, (2) traits associated with urbanization (urbanization markers) or (3) traits associated with specific ecosystem properties (functional markers) best capture actual differences in colonisation, water infiltration and decomposition in woodlands across a rural-urban gradient (Montreal, Canada). We use Procrustes superimposition and Mantel tests to compare the fit of each method. We propose the functional Mahalanobis distance to measure the distance of an urban woodland from a reference range of multifunctionality. All three methods were significantly congruent with actual differences in ecosystem multifunctionality, but the strength of the rank-order correlations varied widely. Species composition and urbanization markers had a similar but weak correlation with differences in multifunctionality. Importantly, the mismatch between species composition and multifunctionality increased with urbanization. Functional markers captured ecosystem multifunctionality better than either species composition or urbanization markers. Commonly used species- and general trait-based approaches were poor measures for multifunctionality in our urban woodlands. Functional markers rely on vegetation inventories already routinely collected by land stewards and openly available trait information: they may provide a cost-effective way of capturing multifunctionality in urban systems. More broadly, the functional Mahalanobis distance provides a quantitative measure of site-level multifunctionality that allows land stewards to compare woodlands with a reference range of variability in a format that can directly inform conservation decisions.

    查看更多>>摘要：? 2022 The AuthorsWe used an eye-tracking technique to investigate the effect of green zones and car ownership on the attractiveness of the courtyards of multistorey apartment buildings. Two interest groups—20 people who owned a car and 20 people who did not a car—observed 36 images of courtyards. Images were digitally modified to manipulate the spatial arrangement of key courtyard elements: green zones, parking lots, and children's playgrounds. The participants were asked to rate the attractiveness of courtyards during hypothetical renting decisions. Overall, we investigated whether visual exploration and appraisal of courtyards differed between people who owned a car and those who did not. The participants in both interest groups gazed longer at perceptually salient playgrounds and parking lots than at greenery. We also observed that participants gazed significantly longer at the greenery in courtyards rated as most attractive than those rated as least attractive. They gazed significantly longer at parking lots in courtyards rated as least attractive than those rated as most attractive. Using regression analysis, we further investigated the relationship between gaze fixations on courtyard elements and the attractiveness ratings of courtyards. The model confirmed a significant positive relationship between the number and duration of fixations on greenery and the attractiveness estimates of courtyards, while the model showed an opposite relationship for the duration of fixations on parking lots. Interestingly, the positive association between fixations on greenery and the attractiveness of courtyards was significantly stronger for participants who owned cars than for those who did not. These findings confirmed that the more people pay attention to green areas, the more positively they evaluate urban areas. The results also indicate that urban greenery may differentially affect the preferences of interest groups.
