“有机建筑”在酒店设计中的启迪与应用

美国建筑师赖特在20世纪初提出了"有机建筑"的概念,提出建筑不应该是钢筋混凝土的堆砌物,应当赋予建筑鲜活的生命,将自然观渗透于建筑结构美学、内外空间、建筑材料与色彩搭配中,同时也彰显了东方大家老子的"道法自然"。在当今世界生态危机的严峻的环境下,有机建筑在节约自然资源、保护环境和以人为本的理念上更具有现实意义。本文以太湖某酒店投标案例为例,阐述了在"有机建筑"理念的启迪下,在建筑的空间连续性、简洁与真实性、自然生态性等方面与太湖景观相互渗透,相互交融的设计手法,使建筑与环境形成有机的统一体。

Sustainable Development and the Basic Value of Natural Environment

Contrast with artificial environment, the multi-level self-organizational system of nature has great gain. Sustain-able material environment should respect nature: non-rubbish and super-cycle quality of natural ecosystem offers the material source of human development, fractal structure of nature offers new field of space and information source to this high-density and information-based society, dissipative structure of nature links the new system of energy with whole ecosystem organi-cally, and life-chain regulation is the base of sustainable life environment. Nature guarantees the physical healthy environ-ment by its all-dimension healthy factor, constructs the mental healthy environment by its quality of co-ordinate and chaos, so that guarantees the whole emergence of sustainable develop-ment on the 'super-science' level. In the view of sustainable development, construction, green economy and human health are basic fields. With the concept of ecosystem regulation, we can relate these fields organically and fulfill the task of human health, welfare and sustainable development. Ecosystem regulation is the base of sustainable development's new para-digm.

Study on Disturbances and Its Effects on Nature Reserves

As a widespread natural phenomenon, disturbances are considered a discrete event occurring in a natural ecosystem within various spatial and temporal scales. The present paper discusses the types of disturbances and their influence on the ecologic system in nature reserves. It is shown that nature reserves are facing a great challenge dealing with these disturbances. A rational control for disturbances should be improved in order to promote the healthy development of nature reserves this could be done by enhancing the publicity and training of environment protection, coupling management with communities around and other nature reserves, effective management methods, rational planning, and supporting nature servers.

Taxonomic Distinctness of Macrofauna as an Ecological Indicator in Laizhou Bay and Adjacent Waters

In this paper, we assessed the ecological and biodiversity status in the Bohai Sea through a quantitative survey on mac-rofaunal community at 25 stations in Laizhou Bay and adjacent waters in the autumn of 2006.We tested the robustness and effectiveness of taxonomic distinctness as an ecological indictor by analyzing its correlation with species richness and natural environmental variables and by analyzing other ecological indicators (Shannon-Wiener H' and W statistics from Abundance Biomass Comparison curve).Results so obtained indicated that the benthic environment of the study waters in general is not under major impact of anthropogenic disturbance, but some stations in Laizhou Bay and along the coast of the Shandong Peninsula and even in the central Bohai Sea might be moderately disturbed and showed signs of ecological degradation.The taxonomic distinctness measures △+ and Λ+ were independent of sampling effort and natural environment factors and were compliant to other ecological indicators.Further application of the taxonomic distinctness indicator to assess marine biodiversity and ecosystem health on a larger regional scale with historical data seems promising.

Ecology, Biology and Biometry of an Endemic Fabaceae： Genista Saharae Cosson and Durieu

Genista saharae Cosson and Durieu, endemic Saharan Africa, is a spontaneous fabaceae dunes south of M＇sila （Algeria）. Perfectly adapted to arid and sandy soils, this species is a remarkable plant for dune fixation and thus fights against desertification. The objective of this study is to provide local species to various development programs of steppe ecological systems in nature and therefore ensure the rehabilitation of these species while considering the conservation of biodiversity and sustainable management of biological resources steppe. After a field survey and stratified sampling, the methodological approach has taken into account three types of analysis： a biometric analysis of a population of 100 individuals of this species, the second analysis on its biology at last an analysis of an ecological factor dealing with the accuracy governing the distribution of this species in Maiter Oued in the south of M＇sila. The results have clarified the ecology of this species to better understand its biology and to develop statistically a diagnosis on the phenology and morphology of various organs （pods, seeds, leaves） of Genista saharae Cosson and Durieu.

Hendra Virus Re-visited

Hendra virus,a novel member of the family Paramyxovirus that has emerged from bats in Australia,causes fatal disease in livestock and humans. Eleven spillover events have been identified since the first description of the virus in 1994,resulting in a total of 37 equine cases and six human cases. All human cases have been attributed to exposure to infected horses;there is no evidence of bat-to-human or human-to-human transmission. Low infectivity and a high case fatality rate are features of Hendra virus infection in both horses and humans. The temporal pattern of spillover events suggests seasonal factors(plausibly be environmental,biological or ecological) as the proximate triggers for spillover. Minimisation of the future occurrence and impact of Hendra virus infections requires an understanding of the ecology of flying foxes,of virus infection dynamics in flying foxes,and of the factors that promote spillover. Management strategies seek to minimize the opportunity for effective contact between bats and horses,and limit potential horse-to-horse and horse-to-human transmission. Incomplete knowledge of the ecology of the virus,of the proximate factors associated with spillover,and the inherent difficulties of effectively managing wild populations,preclude a management approach targeted at bats.

Comparative Study on Differences of America-China Eco-Literature Viewpoints From the Perspective of Academic Compatibility

Facing the broad ＂eco-literature＂ subjects, this paper, first of all, taking eco-literature viewpoint and the theoretical connotation of eco-criticism viewpoint itself as the starting point, conducts a contrast study from the cultural origin-tracing on the American eco-literature viewpoint under the Western Bible vision and the Chinese natural eco-literature viewpoint of＂Oneness of Men and Nature＂ through the parallel comparison method; then from the visual angle of influential research is to further explore the academic compatibility in academic research： namely, the Western ecological literature consciousness begins to appear under the premise of the Western ecological civilization being destroyed, while the China＇s natural eco-literature of＂Oneness of Man and Nature＂ is based on a kind of unconscious affinity between people and nature in primitive age. Here it is necessary for us to point out that they cannot be mentioned in the same breath, because the modern ecological criticism is not the reduction of an ancient ecological thought, and also will lead to the academic non-compatibility in academic research. So only by correcting the people＇s misunderstanding in cognition, can we reach the unity of the natural ecological viewpoint and man civilized viewpoint so as to keep the harmony between human beings and nature.

Impacts of Anthropogenic Stresses on Biodiversity： A Case Study of Lumbini, Nepal

Biodiversity conservation denotes the protection, management and utilization of resources available on or below the surface of the earth. The sustainability of biodiversity resources rely on the ecological balance. A sound planning based on ecological background and human needs provide successful management of natural resources. The study area, Lumbini harbors rich biodiversity and provide significant habitats for several species of birds, mammals, herpetofauna and fish. There are four major habitat types in Lumbini area-farmland, forest, grassland and wetland. The resources outside the Lumbini Development Trust and surrounding villages have already depleted due to excessive human interference in natural resources. Lumbini and its vicinity are rich in natural resources but poor in terms of infrastructure and delivery of services. The areas are losing natural wealth to pay for development. Rural areas around Lumbini are confronted with worsening poverty, ill health, illiteracy and continuing deterioration of natural ecosystems on which the local residents depend for their well-being. The only way to assure a safer and more prosperous future in Lumbini area is to deal with environment and development issues in a balanced manner. This research work attested that the local stakeholders feel ownership on people centered conservation.

Regional Ecological Vulnerability Assessment of the Guangxi Xijiang River Economic Belt in Southwest China with VSD Model

The interactive effects of natural and human factors on ecosystems have been well studied, and the quantitative assessment of large-scale ecological vulnerability caused by natural and human factors is now one of the most active topics in the ifeld. Taking the Guangxi Xijiang River Economic Belt in southwest China （GXEB） as a case study, we assess ecological vulnerability based on the Vulnerability Scoping Diagram （VSD） model. The indices system is decomposed into three sub objects, ten elements and 25 indicators layer by layer, which included factors from both natural and human ifelds. Results indicate that zones with lower, middle-lower, middle, middle-higher and higher vulnerability account for 11.31%, 22.63%, 27.60%, 24.39%, and 14.07%, respectively. The western and eastern parts of GXEB are more vulnerable than the central part and the mountain and urban areas are of higher vulnerability than the basins and river valleys. Compared with a vulnerability assessment based on natural factors only, it is concluded that human activities indeed cause the transition from naturally stable zones to vulnerable zones. The nature-dominated vulnerable zones are different with human-dominated ones in size and distribution, the latter being smaller, more scattered and distributed in urban areas and their surroundings. About 53%of total construction land is distributed in zones with middle and middle-higher ecological vulnerability;less vulnerable zones should attract construction in the future. Relevant suggestions are proposed on how to reduce vulnerability according to inducing factors. The VSD model has a signiifcant advantage in the quantitative evaluation of ecological vulnerability, but is insufficient to distinguish nature- or human-dominated vulnerability quantitatively.

Scale Dependence of Soil Spatial Variation in a Temperate Desert

Spatial variation is a ubiquitous feature of natural ecosystems, especially in arid regions, and is often present at various scales in these regions. To determine the scale dependence of the heterogeneity of soil chemical properties and the dominant scales(factors) for soil heterogeneity in arid regions, the spatial variability of soil resources was investigated in the Gurbantunggut Desert of Central Asia at the scales of 10-3, 10-2, 10-1, 100, 101, 102, 103and 104m(from individual plant to population or community to ecosystem). Soil chemical properties including pH, electrical conductivity(EC), organic carbon, total nitrogen, available nitrogen, total phosphorus, and available phosphorus were considered in the investigation. At a scale of 10-1m, which represented the scale of individual plant, significant enrichment of soil resources occurred under shrub canopy and "fertile islands" formed in the desert ecosystem. Soil EC exhibited the largest heterogeneity at this scale, indicating that individual plants exerted a great influence on soil salinity/alkalinity. Soil nutrients exhibited the greatest heterogeneity at a scale of 102m, which represented the scale of sand dune/interdune lowlands(between communities). The main important factors contributing to soil spatial heterogeneity in the Gurbantunggut Desert were individual plants and different topographic characteristics, namely, the appearance of vegetation, especially shrubs or small trees, and existing sand dunes. Soil salinity/alkalinity and soil nutrient status behaved differently in spatial heterogeneity, with an inverse distribution between them at the individual scale.
