居住区绿地空间的植物尺度与种植密度研究 总被引：1，自引：0，他引：1
伴随着人们物质生活水平的提升,人们对于居住区的绿化环境要求也越来越高。为与居住区建筑建设速率相匹配,居住区植物景观建设往往期盼能够达到立竿见影的效果,因此忽略了对植物空间尺度的把控和对植物种植密度的合理化设计。植物尺度与种植密度决定了植物景观的空间形态以及空间之间的相互关系,对居住区绿地空间的营造有着至关重要的影响。分别从植物个体空间尺度、植物种植尺度与种植密度以及杭州居住区绿地案例3个部分综合分析居住区植物景观空间设计中有关于植物的尺度应用问题以及植物的种植密度问题,并给出空间营造改善的相关建议。讨论如何从植物造景的角度,创造出舒适宜人的居住区绿化空间,提升居住区绿地环境的整体质量。 相似文献

Private on-site sewage systems serve residential development in rural landscapes throughout the United States. In the State of Wisconsin, three major types of private sewage systems facilitate residential development on sites that span gradients in slope, soil permeability, depth to bedrock, and depth to water-table. Conventional soil-absorption sewage treatment systems are constructed on sites with minimal physiographic constraints; more highly engineered alternative sewage treatment systems are installed on sites with moderate to severe constraints; holding tanks provide no on-site sewage treatment and are employed on sites with the most severe physiographic limitations. An environmental impact statement (EIS), prepared in 1979 on the proposed widespread use of alternative private sewage systems, suggested that alternative systems might facilitate in-fill development on poor sites near existing cities and lead to compact, higher density development patterns.The research reported in this paper tested the validity of this EIS scenario by comparing development patterns associated with a sample of conventional systems, alternative systems, and holding tanks installed during the 1980s in Ozaukee County, Wisconsin. Land use data, soils data, and other site attribute data were assembled and analyzed in a vector geographic information system (GIS). Because each type of private sewage system has a unique set of siting criteria, the three sets of sampled systems are located in significantly different physiographic regions within the County. Collectively, installations of all three systems facilitated scattered residential development throughout the rural landscape. This development consists of relatively small residential patches dispersed within an agricultural matrix. Wastewater management technology, if not constrained by public policies or other socioeconomic factors, can be an important anthropogenic factor influencing both the process and pattern of landscape change. 相似文献

A glasshouse pot experiment is described comparing the growth reponse, nutritional , status and heavy metal content of Petunia grandiflora in an impoverished acid sandy soil amended with peat or composted sewage sludges and refuse. The composts consistently out-performed peat as soil améliorants because of greater nutrient availability. However, results indicated that rates of application of composts to soil should be adjusted according to the conductivity of the applied material and the salt tolerance characteristics of the plant species to be grown to avoid detrimental effects on plant growth. There were no phytotoxic effects on plant growth due to contamination of the composts with heavy metals irrespective of the level of incorporation into soil, indicating that proposed lower metal limits for composts compared with sewage sludge would be unnecessarily restrictive to compost use. Composted sewage sludges and refuse are shown to have considerable potential for use in the amenity and landscape industry for improving impoverished soils. 相似文献

Recycling sludge as a soil amendment has become a viable option for sludge disposal. However, such application can lead to soil pollution because of its enrichment in contaminants, especially heavy metals. To identify an effective means to ensure the ecological safety of sewage sludge landscape utilization, a glasshouse experiment was conducted by mixing sewage sludge at 0%, 15%, 30%, 60%, and 100% (V/V) amendment ratios to landscape soils and planting five common landscape plants (Aphelandra ruellia, Syngonium podophyllum, Schefflera odorata, Alocasia macrorrhiza, and Dianella ensifolia). Sludge amendment significantly improved fertility and moisture retention capacity of soil, but dramatically increased the contents of Cd, Pb, Cu, and Zn. Compared with lateritic red soil (CK), sludge amended-soils increased the relative growth rate of landscape plants and enhanced their nutrient uptake and heavy metals accumulation. A rate of 30% or less of sludge application showed positive growth effects for all five landscape plants, and did not cause potential ecological risks of heavy metals to landscape soils. However, rates of 60% or higher posed very high potential ecological risk in multiple metals, particularly in Cd. Interestingly, S. odorata, A. ruellia and A. macrorrhiza could alleviate the ecological risks of Cd, Cu and Zn, respectively, and these results were confirmed by data of relative changes in heavy metal contents in post-experiment soil. Our results suggest that attention to reducing the environmental risks of heavy metals in sludge utilization as landscape soil-amendments should not only be paid to controlling the application dosage of sludge but also to planting suitable plant species. 相似文献
