在老城区景观更新过程中,发现存在许多功能复杂、差异大的建筑空间组合区,在小区域范围内建构多元化的景观空间以满足不同使用人群的需求,是这些多功能区需要解决的问题。案例地贵州师范大学阳光苑位于贵州省贵阳市云岩区,是典型的老城区小尺度的活动空间,从空间序列的角度出发,对其植物配置进行调查分析,研究其在多功能空间组织中的作用和优势。结果表明:植物的种类、数量和形态特征以及不同的配置方式是影响多功能区不同人群使用需求的重要因素。得出以下结论:①进行多功能区植物配置时,分清主次,利用基调树种和季相变化烘托主环境氛围;②按照“少即是多”的原则进行均衡配置,并且使植物与其他景观要素有机结合;③利用植物的生物学特性进行配置,创造丰富的竖向空间,满足不同人群的使用功能。研究结果可以为同类型的区域交往空间提供植物配置策略,优化和提升老旧社区的空间品质。 相似文献

Landscape Position, Local Environmental Factors, and the Structure of Molluscan Assemblages of Lakes
Biotic communities are structured by both regional processes (e.g., dispersal) and local environmental conditions (e.g., stress).
We examined the relative importance of landscape position (position within the hydrologic flow system and distance from other
lakes) and local environmental factors in determining the assemblage structure of lake-dwelling snails and fingernail clams
in a boreal landscape. Both landscape position and local environmental factors were highly influential in structuring the
molluscan assemblages. In canonical correspondence analysis, 53.6% of snail and 48.2% of fingernail clam assemblage composition
were accounted for by both sets of variables. The pure effects of landscape position were higher than those of environmental
variables, and a considerable amount of variability was shared by the two sets of variables. In regression analysis, 95.5%
of snail and 62.2% of fingernail clam species richness was accounted for by the explanatory variable groups, with most of
the variability being related to shared effects, followed by landscape position. The effects of landscape position on species
composition suggest that passive dispersal increases the similarity of molluscan assemblages in adjacent lakes. This process
does not lead to an overall homogenisation of assemblage composition across the landscape, however, because local conditions
set a strong environmental filter, excluding species that arrive at an unsuitable lake. These environmental filters may reflect
either extinction probability (area, productivity) or species niche differences (calcium levels, abiotic stress). Landscape
position may also be important in maintaining the species richness of lake-dwelling molluscan assemblages. By providing potential
colonists, nearby source lakes are likely to be important in countering local extinctions. Our test of the relative importance
of landscape position and local drivers of assemblage structure was partly confounded by their co-variation. Nevertheless,
studying the relationship between landscape position and local variables is useful because it can tell us about the importance
of local and regional processes in shaping lake communities. 相似文献

The loss of biodiversity in productive ecosystems is a global concern of the last decades. The Rolling Pampas of Argentina is an intensively cropped region that underwent important land use and landscape change, with different impacts on biodiversity of both plants and animals. Land use type and habitat complexity are hypothesized to be the most important factors determining species richness in agro-ecosystems. But it is not easy to define these attributes in an unambiguous fashion, or determine their interactions at different spatial scales. A fuzzy logic approach allows overcoming some of these problems by using linguistic variables and logic rules to relate them and formulate hypothesis. We constructed fuzzy logic models to study how bird species richness in the Rolling Pampas is related to land use and habitat complexity, and how these variables interact at two spatial scales. Results showed that at the local scale, landscape complexity is the most important factor determining species numbers; trees and bodies of water are the most influential complexities. The effect of local scale landscape attributes was modified depending on the context at broader scales, so that agricultural sites were enriched when surrounded by more favorable landscapes. There was a high dispersion in the predicted/observed value relationship, indicating that landscape factors interact in more complex ways than those captured by the models we used. We suggest that the fuzzy logic approach is suitable for working with biological systems, and we discuss the advantages and disadvantages of its use. 相似文献

Choosing appropriate plants for urban landscapes is vital to avoid potential financial and environmental losses that may occur if all selection parameters are not taken into account. A methodology has been developed to assist landscape architects, planting designers, and urban horticulturists in the plant selection process. Tehran has been picked as a case study due to its arid and semi-arid climate which poses more challenges in front of an expert. After grouping plants, selection parameters have been defined for each plant group. Plant species were comparatively graded for each parameter by a group of eight specialists. Analytical hierarchy process (AHP) technique and hierarchical cluster analysis have been utilized to find the most adaptable plant species for the area according to the main selection parameters of zone tolerance, urban conditions, esthetics, maintenance, growth characteristics, and specific features. Several new plants were ranked high in the final tables suggesting that the urban landscape of Tehran has a great potential to become more attractive, less allergic, and less costly, as well as consuming less water. Before introducing new plants to the urban environment, they should be experimented on in small numbers for several years to confirm that they will not change the ecology of the whole region through invasion or posing a threat to any local plant species. 相似文献

Plants in living walls face challenges from intraspecific and interspecific competition from plants around them, as well as water and nutrient availability in the growing media. This paper explores these challenges using four different species of hardy perennials.Campanula poscharskyana ‘Stella’, Geranium sanguineum ‘Max Frei’, Sesleria heufleriana and Veronica officinalis ‘Allgrün’ were grown in two types of vertical growing media, made of either coir or stone wool, in transparent boxes under greenhouse conditions. In the media, plants were placed above each other, two plants of same species, two plants of different species, or a plant grown alone. Root frequency was registered over 56 days and the activity of individual root systems was studied through uptake of 15N. In addition, plant dry weight and N content as well as water content in the growing media were measured at cessation of the experiment.Shoot and root growth as well as nutrient content in plants were higher in coir than in stone wool and plants placed at the top position had significantly higher biomass than at the bottom position. The stone wool media had significantly higher water content in the lower part of the media while the coir media had water more evenly distributed. Species differences in root frequency were found. Campanula and Geranium showed strong root growth and had root frequencies of up to 0.9, whereas Sesleria and Veronica had less root growth, in some cases only root frequencies around 0.3. The species reacted differently to root competition and planting position and there were differences in the competitive ability between the species. Campanula and Geranium were not affected by competition, whereas both Veronica and Sesleria showed altered root growth due to competition depending on the growing medium. When Geranium was grown above Veronica in stone wool, plant biomass and 15N uptake increased in Veronica indicating environmental modification, with one species improving the growing conditions for another.The results revealed that growing plants vertically in a living wall is complex, and that choice of growing medium and species composition is important for a successful living wall. Planting combinations should therefore be tested before being used in commercial applications. 相似文献
