绿色建筑世界观 仿生——可持续建筑“师法自然”

原始之绿——成功复制大自然的精髓想象一下,大自然是怎么让一座建筑凉快下来的？看看日本大阪大学的做法吧!在这里,营造商、建筑师和设计者们都在尝试寻找一种更好更佳的“建筑绿化”模式,他们的关注迅速地转向大自然本身——原始的绿意,而这样的方案显然已被证实在真实世界里是的确可行的：在该大学的前沿理论研究中心,设计者们“偷”来了森林的“魔法”,直接把树叶用作建筑遮荫的“衣裳”。     

自来水，安全吗？

自慈禧太后在1908年批准建立中国第一家自来水厂——京师自来水股份有限公司之时算起,中国的自来水已经有百年历史。经过百年的历史变迁,人们从最初对自来水“身所未经,则以为异”,到如今自来水对于人们生活的重要性已经不言而喻。

特别关注:探索中国特色环境保护新道路之污染防治篇(上)

在过去的岁月中,发达国家大多走过了一条先污染后治理牺牲环境换取经济增长的环保道路,造成了严重的环境危害。然而崛起     

世人瞩目中国可燃冰战略

不久前,两则有关中国可燃冰的消息引起人们的关注。一是新华网发布的“南海北部可燃冰储量达185亿吨油当量”;二是《21世纪经济报道》称,“南海天然气水合物富集规律与开采基础研究”项目已通过了国家重大基础研究发展计划（973计划）组织的审查,此举意味着中国已将可燃冰研究列入国家战略。由于近几十年来经济快速增长推动能源消费呈几何式跳跃增长,并由能源出口国变为净进口大国,因此中国能源政策一直受到国际舆论的关注。此次中国进军可燃冰的消息,自然也不例外。

Phragmites australis and Typha orientalis in removal of pollutantin Taihu Lake, China

Two plant populations of Phragmites australis and Typha orientalis grown in gravel and sediment substrate were studied to assess their capabilities for purifying polluted water in Taihu Lake, China. The substrate displayed most significant effects on the suspended matter (P < 0.01), with the reduction of 76%-87% and 52%-63% for P. australis, and 83%-86% and 45%-62% for T. orientalis in gravel substrate and sediment substrate, respectively. Both species and substrates significantly decreased the N and P conc...     

Acid deposition critical loads modeling for the simulation of sulfur exceedanceand reduction in Guangdong, China

The current acid deposition critical loads in Guangdong, China were calculated using the PROFILE model with a 3 km × 3 km resolution. Calculations were carried out for critical loads of potential acidity, actual acidity, sulfur and nitrogen, with values in extents of 0–3.5, 0–14.0, 0–26.0 and 0–3.5 kmol/(hm2·year), respectively. These values were comparable to previously reported results and reflected the influences of vegetation and soil characteristics on the soil acid buffering capacity. Simulations of S...     

Concentrations and chemical forms of potentially toxic metals in road-deposited sediments from different zones of Hangzhou, China

The 25 road-deposited sediments were collected from five different land-use zones (industrial, residential, commercial, park, and countryside) in Hangzhou, China. The concentrations of metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in these samples were determined using the ICP-AES after digestion with the mixture of HNO3-HF-HCl (aqua regia), and chemically fractionated using the modified BCR (the European Community Bureau of Reference) sequential extraction procedure. The highest metal concentration level was detected in the sample from industrial zone and commercial zone having heavy traffic. While the lowest metal level was noted in the street dust sample from residential zone, park, and countryside zone. The mobility sequence based on the sum of the BCR sequential extraction stages was: Zn (80.28%), Pb (78.68%), Cd (77.66%) ＞ Cu (73.34%) ＞ Mn (67.92%) ＞ Co (41.66%) ＞ Ni (30.36%) ＞ Cr (21.56%), Fe (20.86%). Correlation analysis and principal component analysis were applied to the data matrix to evaluate the analytical results and to identify the possible pollution sources of metals. Factor analysis showed that these areas were mainly contaminated by three sources, namely lithology, traffic, and industry.     

Nitrification potentials of Chinese tea orchard soils and their adjacentwasteland and forest soils

To investigate the nitrifying activities of di erent soil types, soil samples collected from 8-, 50- and 90-year old tea orchards, theadjacent wasteland, and 90-year old forest were measured for their nitrification potentials using the conventional soil incubation and theliquid incubation method. Among di erent soil types, the nitrification potential of soil in tea orchards was higher than that of wastelandand forest soils. The slurry shaken liquid incubation method was confirmed to be more accurate and have reliable results than thesoil incubation. Interestingly, experimental result revealed that the generally applied pH value of 7.2 for the liquid media was not theoptimal pH for these acid soils with a strong bu er capacity. This suggested that tea orchard soils may have nitrifiers requiring pHneutralcondition for the best activity. Our data also showed that treatment with the commonly used nitrogen fertilizer urea significantlyimproved nitrification potential of the soils; such enhancement e ect was stronger on all of three tea orchard soils than on wastelandand forest soils, and also stronger on the younger (8- and 50-year old) tea orchard soils than on the older one (90-year old).
