Urban parks can provide a resource for maintaining and increasing bird biodiversity. However, little research has been conducted to show the differences in bird community diversity between parks adjacent to mountains and rivers in the city center of highly urbanized areas. This study analysed whether the bird composition and species diversity differed between parks adjacent to Baiyun Mountain (hillside parks) and Pearl River (riverside parks) in Guangzhou, South China. From January 2018 to December 2020, 137927 birds representing 206 species were recorded. The results indicated that the number of species and individuals of birds were higher in hillside parks than in riverside parks in each season. The number of species and individuals was also higher in hillside parks than in riverside parks in different functional groups according to bird food type, residential type, and ecological type. The number of species shared by the two types of parks was 120. The unique birds' species number in hillside and riverside parks were 67 and 19, respectively. Bird diversity in terms of richness and Shannon index was higher significantly in hillside parks than in riverside parks in summer. Principal component analysis of environmental traits of 18 parks showed that plant traits in parks have relatively high and positive contribution. Correlation analysis indicated that bird diversity was positively affected by water area, the highest altitude, habitats diversity and tree evenness in park, while negatively regulated by building coverage around each park. The top 20 most abundant bird species accounted for 87.5% of the total birds in the study period. Nycticorax nycticorax, Urocissa erythroryncha and Podiceps ruficollis were observed more frequently in hillside parks, while Pycnonotus aurigaster, Passer montanus, Acridotheres cristatellus were observed more frequently in riverside parks. Principal coordinates analysis also indicated that bird communities significantly differed between hillside parks and riverside parks. In conclusion, our findings highlight the importance of conserving mountains and rivers as buffer zones for serious anthropogenic disturbance in the city center. We propose that the conservation of hillside parks is a priority strategy for enhancing urban birds biodiversity. 相似文献

Parks are recognised as important elements of urban green infrastructure and for providing many benefits to city residents. In countries where urban growth is unplanned and sprawling, green space provision falls behind, inadequate amounts are provided or spaces are not located in the most effective places. Tehran, the capital of Iran, has experienced huge growth in population and corresponding sprawl in recent years. There has been no study of the effectiveness of parks as part of the range of green spaces in the city − their location, accessibility within the urban structure, relationship to the socio-demographic character of the population, amount per capita or quality and condition. Using a combination of existing data supplemented by new data from site surveys, this study firstly looked at the citywide scale of public open space in relation to population and socio-economic patterns. Second, a representative sample of 16 parks was examined in terms of their accessibility within the urban street structure using space syntax. The syntactical results were correlated with several different aspects of each park collected and rated on a 1–5 scale. The results showed a wide range of availability of parks with no specific pattern related to whether the district is better off or poor. The data on green space per district was often heavily biased by the presence of large areas of forest park or non-recreational land which gives a false picture.Many of the best parks are poorly integrated into the street network and found in the better off districts yet are very popular because they are “destination” parks in cooler, hilly areas. Poorly integrated parks in the inner city districts tended to show lower levels of maintenance, were often little used and had vandalism. Much more attention is needed to provide green space in an equitable way. 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

Existing studies have seldom used large-scale trajectory data to analyze jogging activities in urban parks. Most of them have relied on traditional questionnaires and on-site interviews. Therefore, this study aims to uncover the characteristics and the potential influencing factors of jogging activities based on trajectory data recorded by a mobile app, using the case of Chongqing city. The results show that urban parks with high jogging flow are mainly distributed within the inner ring road of Chongqing, whereas urban parks with low jogging flow are newly built outside the inner ring road. The volume of jogging flow in urban parks in the spring and summer is higher than that of autumn and winter, and the volume on weekends is higher than that of weekdays. The peaks of jogging in urban parks vary across space and over time, leading to different spatiotemporal patterns. Urban parks along the subcenters, riversides, and airport corridors have morning (6–7 a.m.) and evening peaks (7–8 p.m.). Urban parks in the newly urbanized areas and industrial zones have evening peaks. The regression models show that walking loops and waterscapes have positive effects on jogging flow. The landscape shape index of urban parks and the distance to the city center negatively affect the jogging flow. Finally, the study indicates the possibility of using large-scale trajectory data to analyze jogging activities, which is helpful for urban park planners and managers to improve the frequency of jogging activity. 相似文献

Biodiversity in urban green areas has been widely explored in several bird studies because birds are known to be important bio-indicators. Many studies have investigated the different responses of bird communities to urbanization and land use changes in urban environments. However, there are still important knowledge gaps related to the impacts of the heterogeneity, spatial structure, and connectivity of green areas on avian diversity. Such information is needed for sustainable urban planning. In this study, we focused on the comparison of bird communities between urban parks in the heritage city of Olomouc and hardwood floodplain forests in the vicinity of the city. The results of the study indicate the high importance of urban parks for the maintenance of bird diversity even though urban parks are man-made habitats. The results highlight the importance of some native vegetation structures in urban parks (old trees, bush ecotones) for maintaining urban bird biodiversity. Some implications of the results can be widely used as a decision support tool for the management of urban green areas and for the planning of ecological networks in urban landscapes. 相似文献

For well over a decade, urban political ecology has been concerned with the neoliberalization of infrastructure as a key site of struggle in the reproduction of urban space. While urban forests, trees, and parks have not featured as prominently in that literature as other resources (e.g., water), they are increasingly managed and promoted as a form of “green” infrastructure by city governments eager to ally themselves with new environmentally-oriented framings of the modern city. Yet, the relationship between these new forms of green infrastructure and the neoliberalization of the city, in particular their ability to enable new ways of taking about the city and nature, and to constrain others, has been understudied. In this paper, I examine the ways in which urban parks are enrolled in political struggles to reorient the techniques of urban governance toward entrepreneurialism as the only viable model for economic development. Through a case study of Philadelphia's Fairmount Park System, I examine a series of events during the previous three decades in which Fairmount Park has become subject to this reorientation toward entrepreneurialism. Specifically, I examine how parks, no longer treated as spaces of “nature”, have been reframed as self-supporting constituents of a business-minded urbanism, promotional tools for the attraction of new labor to the city, and a reinforcement of the notion of entrepreneurialism as the inevitable urban development strategy for the 21st century. Yet, I also argue that these transformations are always in a process of negotiation. Even as parks become subject to these dominating discourses, new park construction is a site in which the conceptual assumptions that underpin neoliberal urban policy aren’t frictionlessly transferred from one instance to another but, even when successful, require significant work to overcome competing visions of urban nature. 相似文献
