2006年8月,国务院批准的<天津城市总体规划(2006~2020年)>明确提出:到2020年把天津建成国际港口城市、北方经济中心和生态城市.这个战略决策是以构建城市生态安全为基础,进而实现天津经济社会的可持续发展的目标.因此,建设生态城市既是对天津城市化前景的前瞻性思维,也是一项充满艰巨挑战的生态建设工程,一项造福天津和子孙后代的浩大工程. 相似文献

在风水学的研究中,学者们认为自然界的超微离子和磁场会对人体产生明显的正负影响,并认为在自然界中任何物质都会产生作用于人体的超微离子和磁场,这些能量随着环境不断改变,也随着人体自身场态信息的改变而改变。这些信息能量可以使我们心情愉悦、思维敏捷、健康长寿,也可以使人思维迟钝、神经恍惚、多病早逝!而风水就是在地基、居所布局等基础上增加某种信息符号,以满足人们避凶趋吉的心理要求! 在人的一生中,人体不断与外界进行物质能量和信息的交换,对自然电磁波的变化的反映,必然伴有一些物理和化学现象。人体在外界影响下发生一系列生理、生物化学现象,为风水学的作用机能提供了依据! 相似文献

The quest for sustainability in the design and development of buildings and cities has expressed itself predominantly as a pursuit of ever-greater efficiency. Urban systems have been developed to achieve energy and resource savings in an attempt to eliminate their environmentally negative impacts. The end goal would seem to be to make buildings and cities virtually invisible within the context of the natural environment and to extract humanity from that which is natural. This approach could be termed as a hyper-efficiency sustainability model. In this approach, the impacts of human beings and their functional systems are seen as contaminants that need reduction or removal. Although driven by a desire to preserve the Earth’s natural systems, such an approach ultimately creates greater division between humanity and nature and may not bring sustainability. As an alternative to a hyper-efficiency model of sustainability, a model should be pursued that focuses more on developing an integrative relationship between civilization and environment akin to mutualism in biology. Such an approach, which could be termed as a mutualistic sustainability model, incorporates natural systems and elements into the structures and functions of buildings and cities, with the goal of achieving cooperative and positive interaction between humanity and nature. Such integration can create opportunities to support living organisms and biological systems in an ecologically contributive manner, while fulfilling human infrastructural needs. It offers a more positive alternative to efficiency based strategies and has the potential to establish a healthier and more productive relationship between humanity and the Earth’s natural systems. This paper elaborates on these two distinct approaches to sustainability and presents an examination of recent green building projects and green infrastructure projects. It analyses specific strategies and methods to contrast and compare manifestations of both approaches, providing valuable lessons and insights for designing sustainable buildings and cities. 相似文献

Shaped by European influences, the Brazilian urban landscape was marked by the predominant use of exotic species in planted
areas. In the 19th century along the city streets of Rio de Janeiro, trees were planted at a standard distance from each other.
With time, native species began to be used in the urban landscape. Our purpose was to evaluate the utilization of exotic plant
species in the urban landscape of Rio de Janeiro, evaluate the city’s arboreal deficit, and relate its neighborhood arboreal
density to its economic index. Arboreal deficit represents the negative difference between the total number of expected trees
and the observed number in the streets based in the standard distance used in the past. Twenty native and 40 exotic species
were found in the 1701 streets sampled. A high percent of streets did not have any planted trees and the number of trees was
greater in wealthier neighborhoods. The strong prevalence of exotic species is indicative of the negative impact of human
activity on the biota. Since the municipality of Rio de Janeiro harbors forested areas, the risk for dissemination of exotic
species is high. 相似文献

In the Mediterranean, long-term land-use changes have resulted into landscape mosaics composed of very few ancient woodland remnants scattered across extended post-agricultural woodlands. Patches of ancient woodlands are now suffering rapid urban growth that reduces their area and impact their associated biodiversity. Here we use the case study of Montpellier, one of the most dynamic cities in France, to 1) characterize temporal changes in land covers (between 1860 and 2006) in its area, and 2) using two guilds of fungal bioindicators (i.e., polypores and lichens), to compare biodiversity stakes between ancient and secondary Mediterranean woodlands. We used a combination of historical maps, archives, fungal collections and field survey in eight Quercus ilex patches (4 ancient versus 4 recent replicates) to reconstruct landscapes dynamics and assess biodiversity changes. From the 19th to the 21st century, over half (52.4%) of the ancient woodlands within Montpellier were replaced by other land covers, mainly by urban equipment, while secondary patches (16.8% of the total area) were naturally established. Remaining ancient woodlands show multi-layered vegetation made of multi-secular Pinus halepensis dominating a dynamic understorey made of Quercus ilex and various Mediterranean shrubs. Polypores, but not macrolichens, tended to differ in community composition between ancient and recent woodland patches, with the highest diversity found in ancient woodlands. This study highlights that urban woodland patches of contrasted histories harbour distinct biodiversity stakes to be included in urban planning and provide valuable areas to evaluate biodiversity patterns and dynamics. 相似文献
