Lawns have a significant influence on the cityscape as one of the essential elements of green spaces and an important part of people’s everyday lives. Most people in the Western world view lawns as a compulsory element of the urban landscape, almost an icon, without questioning their social, symbolic, ecological or aesthetic values. This research is a part of the conceptual framework and methodological approaches that are being used in an ongoing transdisciplinary collaboration project to study lawns in Sweden as a social and ecological phenomenon.The overall aim of this study was to investigate social and cultural perceptions of lawns, as well as motives behind decisions about the establishment and management of lawns in Sweden. Two multi-family housing typologies, the ‘Million Programme’ and ‘People’s Homes’, were examined due to their dominance in Swedish cities. We also studied how an alternative vision of conventional lawns can be applied and accepted by urban residents. We estimated lawn cover in multi-family housing areas and links to people’s perception and use of lawns. Questionnaires, semi-structured interviews and observational studies were used (N = 300). Our results showed that people like lawns even if they do not always directly use them. Lawns cover the most significant amount of outdoor spaces in all multi-family residential areas and accompany people everywhere from the house to the schoolyard or park. The total lawn cover in the study areas was 27.8%. Lawns were particularly valued as important places for different outdoor activities (playing, resting, picnicking, walking, socialising) and enjoying the green colour. However people do not want to use a vast monotonous lawn, but a variety of spaces that provide good conditions for different senses (sound, smell, touch and sight) and activities. Alternative lawns were also appreciated by many citizens, politicians, planners and managers. The implementation of new types of lawns requires special planning and design solutions adjusted for each particular neighbourhood. 相似文献

In Britain, managed grass lawns provide the most traditional and widespread of garden and landscape practices in use today. Grass lawns are coming under increasing challenge as they tend to support a low level of biodiversity and can require substantial additional inputs to maintain. Here we apply a novel approach to the traditional monocultural lawnscape by replacing grasses entirely with clonal perennial forbs. We monitored changes in plant coverage and species composition over a two year period and here we report the results of a study comparing plant origin (native, non-native and mixed) and mowing regime. This allows us to assess the viability of this construct as an alternative to traditional grass lawns. Grass-free lawns provided a similar level of plant cover to grass lawns. Both the mowing regime and the combination of species used affected this outcome, with native plant species seen to have the highest survival rates, and mowing at 4 cm to produce the greatest amount of ground coverage and plant species diversity within grass-free lawns. Grass-free lawns required over 50 percent less mowing than a traditionally managed grass lawn. Observations suggest that plant forms that exhibited: (a) a relatively fast growth rate, (b) a relatively large individual leaf area, and (c) an average leaf height substantially above the cut to be applied, were unsuitable for use in grass-free lawns. With an equivalent level of ground coverage to grass lawns, increased plant diversity and a reduced need for mowing, the grass-free lawn can be seen as a species diverse, lower input and potentially highly ornamental alternative to the traditional lawn format. 相似文献

Urban green spaces provide important ecological, environmental, and cultural benefits, including biodiversity conservation and human wellbeing. However, a significant portion of urban green space is currently managed as highly manicured grassy lawns that provide limited ecosystem services. Managing urban green spaces as diverse meadows can have a multitude of ecosystem benefits such as biodiversity conservation, stormwater infiltration, and aesthetics. Relatively little is known about the range of ecosystem services or disservices in managing urban green spaces as lawns versus meadows. In this paper, we separately characterize three major categories of ecosystem services and disservices (provisioning, regulation and maintenance, and cultural) delivered by urban lawns and meadows while highlighting several trade-offs and synergies associated with urban lawn and meadow management strategies. Additionally, we suggest specific research priorities to better evaluate ecosystem services and disservices across these urban green spaces. Understanding ecological, environmental, and cultural trade-offs and synergies of managing different urban green spaces is key to maintaining multiple ecosystem services in urban environments. 相似文献

Soil Phosphorus Variability: Scale-dependence in an Urbanizing Agricultural Landscape 总被引：1，自引：0，他引：1
We examine the hypothesis that human activity changes patterns of variance in soil P (Bray-1) concentrations across several
spatial scales. We measured soil P concentrations and variability for each of four different land uses at three distinct levels
of analysis. Land uses were remnant prairie, lawns, corn fields of cash grain farms, and corn fields of dairies in Dane County,
Wisconsin (USA). For each land use type, levels of analysis were sites (an agricultural field, residential lawn or prairie,
ranging in size from 100 m2 to approximately 20 ha), 10-m plots within a site, and points within the 10-m diameter plot. The rank of mean soil P concentrations
was cash grain > dairy > lawn > prairie. For all land use types, most of the variance was accounted for by site-to-site variation.
Among-site variance was higher for human-dominated sites (0.55, 0.15, 0.14 [log (mg/kg)]2 for cash grain, dairy, and lawn sites, respectively) than it was for prairies (0.07 [log (mg/kg)]2). However, prairies had the highest among-plot variation (0.04 [log (mg/kg)]2) compared to other sites (0.01, 0.002, and 0.01 [log (mg/kg)]2 for cash grain, dairy, and lawn sites, respectively). The results indicate that in this watershed, human activity has increased
the mean soil P and variance of soil P, and shifted the scale of variance to larger spatial extents. Human impacts on landscape
pattern extend to soil properties that affect nutrient flow and eutrophication of surface waters. Because soil P turns over
slowly, the legacy of altered soil P patterns may affect freshwaters for centuries. 相似文献

The replacement of living lawns with synthetic (plastic) grass seems to be on the increase in cities. This paper presents some environmental and societal considerations relating to the installation of artificial lawns to encourage research of the phenomenon at this early stage of emergence. After first discussing the development of ‘third generation’ synthetic grasses that have made artificial lawns more appealing, it then considers how the replacement of living lawns with plastic grass represents a potentially concerning step towards ecological simulation, or the replacement of real ecosystems with simulacra that address cultural desires but remove nature altogether. The paper then examines some of the possible environmental and societal impacts that may result from the replacement of living lawns with their artificial counterparts, and concludes with the presentation of a research framework for investigation of the emerging artificial urban lawnscape. 相似文献

Turf is an important component of the urban and rural landscape. The natural plant formations/biomes that it mimics are the tropical savanna, the temperate grasslands (steppe and the prairies) and the tundra. Turf in a higher or lower degree provides all the ecosystem services of the other types of vegetation. Vegetation ecosystem services that have been previously emphasized include functional, aesthetical, recreational, social, and economic services as well as services related to people psychological or physical health. The purpose of this review is to gather updated information on turf ecosystem services, mainly on how they compare to other types of vegetation, or substitutes, and to suggest some future trends/areas of research.Turf has a unique role in aesthetics and, definitely, provides an irreplaceable surface for recreational sports/activities. From the available information, turf seems to have a higher potential than other types of vegetation for reducing runoff, increasing infiltration, purifying water from sediments and pollutants, controlling erosion, improving soil quality and reducing fire hazards. For the lawn owners the main turf benefits are: first the enhanced property aesthetics, second the increment in property value and third the provision of a recreation area. Turf, as all vegetation, uses water. Without the water its benefits may be reduced or annihilated. Mimicking nature may offer some solutions for saving water: summer brown lawns that green up in the fall, although losing some of the turf benefits, may be an appropriate choice where irrigation is not feasible and are worth some research. Research, should also be done on lawns using a mix of grasses and legumes: the presence of legumes may avoid N fertilization and, possibly allows for clippings removal and usage as biofuel, while keeping the soil accumulation of carbon, preventing N leaching and turning turf’s carbon footprint even more positive. 相似文献
