通常来讲,棕地在美学上并不具备吸引力,风景园林业内推崇棕地的风潮本质上是人们对弹性景观、自我调节、原始景观日渐浓厚的兴趣,其具有较高的生物多样性、多样的生态过程、功能强大和低成本等优势。传统的棕地重建方法是允许现场介入,等待随之发生的连续生态演替,促进新植被类型的自发形成。然而,棕地的植被一般与场地周围的植被类型相近,植被多样性缺乏的棕地,其场地周围通常也是缺乏植被多样性的。在设计实践中,我们应更多关注场地的长期管理,更加着重于对场地现状的生态学和园艺学的理解。通过播种或种植那些不能自行定殖的树木、灌木和草本植物的种子或幼苗,进行长期的管理来塑造景观,最终棕地将形成复杂的植被空间结构和丰富的植被类型。 相似文献

流动地景:大尺度城市景观的生态设计方法 总被引:1,自引:0,他引:1
本文介绍近几年有关景观城市主义的争论,并提出流动地景作为生态设计的另一种命题及其局限性,探讨大尺度城市景观的生态设计方法。比较加拿大多伦多Downsview公园设计及高雄2009世运会场地规划,总结出生态设计的3种可能方法:形象地景、流动地景及时间地景等。生态设计的有效介入,有赖于地景生态网络的策略性位置,可影响植被变迁、生物多样性与水文过程。生态设计非固定的地景形式创造,而是一种策略规划以及机制与过程的设计。大尺度的城市地景空间可以经由精细的及渐进的改造计划,重建城市肌理与自然系统的连结网络。 相似文献

The damage to soil and vegetation caused by mining, unless prevented by careful planning, is usually extreme, because the original ecosystems have had to be grossly disturbed or buried by the mining process. Radical reconstruction is therefore required. In nature this takes place by the well-known processes of primary succession, without human assistance. In the interest of economy and the maintenance of our natural resources, reclamation should attempt to involve the same processes. But primary succession on raw substrates can take several centuries to complete. This paper attempts to analyse what seem to be the factors that limit the processes involved and how they can be overcome by ameliorative treatments. It examines in particular how long this amelioration will take and how much it is likely to cost. Knowing this we are then be able to include a natural approach in land reclamation effectively. 相似文献

Visual preference of the public for vegetation groups in Israel 总被引:1,自引:0,他引:1
Ayala 《Landscape and urban planning》2000,48(3-4)
This study describes a method for classifying and evaluating the visual qualities of selected native and planned forests and other vegetation groups in Israel, and for identifying the degree of visual preference by selected groups of users. Forty-four vegetation groups were selected. Sets of four coloured photographs of each vegetation group were presented to 150 individuals at formal interviews in their homes. Statistical analysis of the answers led to three main conclusions: (1) the existing botanical–ecological classification of vegetation groups used in the study was found to be suitable for the evaluation of its visual qualities; (2) levels of public preference varied and depended on the types of vegetation group; and (3) visual preference for vegetation types could be derived from the individual plants’ physical properties and the latter could be used to forecast the level of public visual preference for a proposed vegetation plan. This study, therefore, suggests a workable evaluation method that could be used for identifying and evaluating public preference for vegetation groups. The findings regarding public preference provide an empirically tested basis for policy planning and the management of other vegetation resources in Israel. 相似文献

Powerline corridor management in Australia has traditionally focused on the complete removal of vegetation using short rotation times due to the perceived fire hazard associated with corridor vegetation. This study assessed vegetation recovery in a powerline corridor, following management, at three sites spanning corridor and forest habitat. Forest and corridor vegetation communities differed significantly between sites and over time. As vegetation recovered, the corridor community became a mix of plants common in the surrounding forest and open areas, changing within the 3-year study from a grass–fern to shrub–sedge community encroached by midstorey species. The current short rotations between management events unnecessarily maintain the corridor in a cycle of degradation, remove resources for native species and may allow introduced grasses and saplings to proliferate in the corridor. Maintaining a shrub layer would help avoid loss of species richness, encourage native species and limit colonisation opportunities of introduced species. Spot spraying emergent saplings and problem plants and mosaic slashing, would keep fire risk low and maintain biodiversity without increasing biomass to dangerous levels. 相似文献

Vegetation uptake of nitrogen and base cations in China and its role in soil acidification 总被引:3,自引:0,他引:3
Vegetation uptake of nitrogen and base cations may be an important source of soil acidity. In this study, the uptake rate of nitrogen and base cations was estimated for each major vegetation type in China. Although the uptake rates of most vegetation types are lower than 2.0 keq ha(-1) a(-1), great variations exist because of the significant differences in net primary productivity and elemental composition. Uptake rates decreased gradually from southeast to northwest, except for the wide-distributed agricultural areas in the east of China, where the nitrogen and base cation uptake rates are near zero. It is evident that this pattern coincides well with the distribution of the annual mean precipitation. However, the geographical distribution of the base cation uptake rate is not entirely the same as that of nitrogen, which indicates the importance of soil conditions in determining the chemical component and hence the uptake rate of different vegetation. The acidity input caused by vegetation uptake is quite high (>0.5 keq ha(-1) a(-1)), and even higher than the current acid deposition and the alkalinity produced by soil weathering in some areas, which indicates that the growth of the plants may contribute significantly to the soil acidification problem in China. 相似文献

In this paper we describe a method for evaluating the concordance between a set of mapped landscape attributes and a set of quantitatively expressed management priorities. The method has proved to be useful in planning urban green areas, allowing objectively documented decisions and helping the resolution of opinion conflicts among decision makers. A case study, involving the evaluation of the vegetation component of a suburban park, is described in detail. The analysis of the case study highlights the power of the method, and of geographical information systems- (GIS-) based decision support methods in general, as a planning aid for green park areas. Their use allowed us not only to propose interesting reorganization plans, but also to give decision makers a better understanding of their own priorities. 相似文献
