乡土植物是园林绿化应用的重要植物资源,本文采用样方法分析了果洛州高寒草甸15个样地野生植物资源。结果表明,果洛州高寒草甸共有22科、81属、143种植物,莎草科(Cyperaceae)、禾本科(Gramineae)的草本植物重要值最高,藏嵩草(Kobresia tibetica)、荨麻(Urtica fissa)、矮嵩草(Kobresia humilis)、垂穗披碱草(Elymus nutans)、紫花针茅(Stipa purpurea)的重要值依次为0.89、0.55、0.54、0.53、0.52,筛选出观叶、观花植物共43属、55种植物。高原自然环境条件是制约野生植物在园林中应用的最大因子,青海果洛地区野生植物资源丰富,但园林绿化应用开发较为落后。 相似文献

That the relationship between remote sensing and landscape ecology is significant is due in large part to the strong spatial
component within landscape ecology. However it is nevertheless necessary to have frequent overview of the interface between
remote sensing and landscape ecology, particularly in the light of developments in the types of image data and techniques.
The use of remote sensing within European landscape ecology provides a rich range of examples of the interface, including
application of some of the latest types of image data. This paper is an overview of the interface that remote sensing has
with European landscape ecology, with seven examples of the application of image data in European landscape ecology and examination
of associated landscape classification issues. These examples are discussed in terms of the trends and the different roles
for image data in landscape ecology that they illustrate, and in particular their classificatory and informational implications.
It is suggested that with regard to classification there is a need for re-examination of the roles of image data. 相似文献

Spatial graphs in landscape ecology and conservation have emerged recently as a powerful methodology to model patterns in
the topology and connectivity of habitat patches (structural connectivity) and the movement of genes, individuals or populations
among these patches (potential functional connectivity). Most spatial graph’s applications to date have been in the terrestrial
realm, whereas the use of spatially explicit graph-based methods in the freshwater sciences has lagged far behind. Although
at first patch-based spatial graphs were not considered suitable for representing the branching network of riverine landscapes,
here we argue that the application of graphs can be a useful tool for quantifying habitat connectivity of freshwater ecosystems.
In this review we provide an overview of the potential of patch-based spatial graphs in freshwater ecology and conservation,
and present a conceptual framework for the topological analysis of stream networks (i.e., riverscape graphs) from a hierarchical
patch-based context. By highlighting the potential application of graph theory in freshwater sciences we hope to illustrate
the generality of spatial network analyses in landscape ecology and conservation. 相似文献

Landscape ecology has provided valuable insights in the relations between spatial structure and the functioning of landscapes. However, in most global scale environmental assessments the representation of landscapes is reduced to the dominant land cover within a 0.5 degree pixel, disregarding the insights about the role of structure, pattern and composition for the functioning of the landscape. This paper discusses the contributions landscape ecology can make to global scale environmental assessments. It proposes new directions for representing landscape characteristics at broad spatial scales. A contribution of landscape ecologists to the representation of landscape characteristics in global scale assessments will foster improved information and assessments for the design of sustainable earth system governance strategies. 相似文献

Contemporary landscape ecology is not unified at all.There are historical, geographical and biological reasons for the lack of unification, as well as differences between science and application. The search for a unified theory of landscape ecology should consider previous concepts such as ‘landscape diagnosis’ and ‘landscape functions’ which were elaborated in Central Europe. Because of the various aspects in a landscape (components, processes, relations), landscape ecology should be regarded as a multidisciplinary, better a transdisciplinary, science where different views and approaches are involved in a holistic manner. The principle of complementarity is helpful to understand and describe the landscape. As a crucial step, the transformation of natural science categories to categories of the human society is brought out. This is realized by land(scape) evaluation and by the elaboration of goals (visions) of landscape development.This revised version was published online in May 2005 with corrections to the Cover Date. 相似文献

Landscape ecology has a temporal dimension, and the role of past processes in shaping landscapes is increasingly recognised.
To date, the interface between landscape ecology and palaeoecology has proved most productive in understanding the impacts
of climate change and in discovering the extent of past human impacts on ecosystems. Further areas of synergy are emerging.
This Perspective gives selected examples of five main areas of synergy between palaeoecology and landscape ecology: dynamic
landscape mosaics; resilience and thresholds; biocomplexity; adaptive cycles; and in the landscape ecology of invasive spread. 相似文献
