河源:绿色之都

河源,素有东江之畔的“绿色明珠”之称。市内空气清新,污染度低,是全国13个大气环境质量达到国家一级标准的城市之一,也是广东省环境保护教育基地,被誉为珠江三角洲和香港的“后花园”。河源自然资源丰富,环境容量大,近几年总体环境质量一直位居全省前茅,优质的天然净水、纯朴的民风,无不令前来的海内外各界人士赞叹不已,这一切又带动了绿色生态旅游的迅速发展。我们相信:随着创建国家环保模范城市的推进和绿色河源的建设,未来的河源一定会成为环境优美的绿色之都。     

河源高新区:“国家级绿色园区”这样得来

<正>日前,工业和信息化部公布第四批绿色制造名单,河源高新区获评"国家级绿色园区"称号,是广东省唯一上榜的园区。如此殊荣,因何花落河源高新区?"我们一直以来都积极践行绿色发展理念、坚守生态环保底线、营造绿色生活环境,走现代河源、生态河源相得益彰的发展新路,推动园区高质量发展。"河源高新区管委会负责人表示,荣誉背后,是河源高新区对生态环境工作一如既往的坚守。     

加快建设绿色河源推进经济发展与环境保护双赢

今年4月，中共中央政治局委员、广东省委书记张德江在茂名考察时提出环保“三个一律”，即“新建项目，凡环保不符合要求一律不准上马；在建项目，凡环保设施未经验收合格的一律不准投产；已建项目，凡经限期治理和改造仍不达标的一律关闭。”。如何贯彻落实“三个一律”精神，加快建设绿色河源，推进全市经济建设、城乡建设与环境建设持续快速健康协调发展，达到经济社会与环境保护“双赢”发展，促进人与自然相和谐？     

循环经济:河源的战略选择

河源市是广东省经济发展的欠发达地区,下辖的五县一区中,有5个县属于广东省的贫困县。近几年,河源市委市政府提出了“工业立市”、“旅游旺市”战略决策,无疑给河源的经济发展注下了催化剂和强心针,实践也证明了这一决策对河源经济的腾飞发展的正确性。但是河源市所处地理位置特殊,它     

绿色公交:为城市绿色服务添彩

绿色交通是城市的绿色名片,为城市优良的环境品质代言。随着现代社会对环境问题重视程度的日益加强,绿色交通的重要性正被越来越多的人所重视,并将其理念化入社会生产生活中。在广州市大力推进绿色交通工程的今天,提高城市空气环境质量,创造舒适洁净的公交环境卫生,斩断“黑尾巴”环保工程等,正在成为众人关注的焦点。

倡议书为在母亲河源头建一片“江苏林”而努力

江苏省共青团员及公民们: 黄河、长江是我们的母亲河,是华夏五千年文明的发祥地,是炎黄子孙繁衍成长的摇篮。 1999年共青团中央与九部委联合提出在全国范围内展开“保护母亲河行动”的号召,我们民间环保组织“徐州绿色之家”积极响应,并于2002年5、6月份赴青藏高原母亲河源头考察、植树。     

绿色公交车

城市公共交通，是城市经济的动脉．是城市经济发展的基础行业，是连接城乡经济的纽带。因此，积极发展城市“绿色公交车”，给城市居民、职工创造一个舒适、美好、安静、清洁、清新的生活环境，势在必行。目前，汽车运行使用的燃料汽油、柴油在燃烧过程中，排出大量的废气，往往使城市低空烟雾弥漫。尘烟经久不散，甚至演变成酸雨，给人们生产生活带来极大的影响和危害。因此，保证城市居民在每人每天能吸入100公升新鲜空气要求的“绿色公交车”便迅猛发展，成为交通的“绿色尖兵”。我国的“绿色汽车”标准化工程已全面展开。有关主管部门…     

河源:科学减排让绿色明珠更璀璨

近年来,河源生产总值连年创新高,经济发展步入快车道.为保护好河源的饮用水源,保护好南粤生态屏障,河源逐步探索出一条既不为发展经济而牺牲环境、又不为消极保护环境而迟滞经济发展的新型工业化道路,并在该科学发展思路的指引下,积极推进"减排"工作,取得了2006年减排指标双降的好成绩.     

绿色水利

绿色是春天的颜色，是“青春”、“生命”、“和平”及“安全”的象征：水是生命之源，没有水的滋润，绿色将失去色彩。然而水也是灾害之源。洪涝灾害就一直困扰着中华民族，成为我们的心头之患。     

青春 责任 梦想 行动 2015年千名青年环境友好使者夏令营侧记

Asbeste Arten,Entstehung, Bedeutung,Problematik

Types of asbestos are distinguished not only by structure, chemical compositon, shape of aggregates, and length and quality of fibers, but also by its formation. Though consisting of quite common elements, deposits are formed only under very special conditions. Its unique combination of properties has created over 3000 fields of application (about 70% in asbestos cement). Great efforts have been made to substitute all types of asbestos by harmless, similarly cheap and versatile synthetic fibers, owing to the unquestioned carcinogenic properties of all asbestos dusts. However, development of such fibers has not made any remarkable progress until recently. Consequently risk to workers in mining and manufactoring, consumers, outsiders, and the environment should be kept as low as possible by intensifying precautions and diminishing emissions.     

Effect of CaO on retention of S, Cl, Br, As, Mn, V, Cr, Ni, Cu, Zn, W and Pb in bottom ashes from fluidized-bed coal combustion power station

This work was conducted to evaluate whether Ca-bearing additives used during coal combustion can also help with the retention of some other elements. This work was focused on the evaluation of bottom ashes collected during four full-scale combustion tests at an operating thermal fluidized-bed power station. Bottom ashes were preferred to fly ashes for the study to avoid interference from condensation processes usually occurring in the post-combustion zone. This work focused on the behaviors of S, Cl, Br, As, Mn, V, Cr, Ni, Cu,Zn, W, and Pb. Strong positive correlations with CaO content in bottom ashes were observed（for all four combustion tests） for S, As, Cl and Br（R = 0.917-0.999）. Strong inverse proportionality was calculated between the contents of Pb, Zn, Ni, Cr and Mn and CaO, so these elements showed association to materials other than Ca-bearing compounds（e.g., to aluminosilicates, organic matter, etc.）. Somewhat unclear behaviors were observed for W, Cu, and V. Their correlation coefficients were evaluated as statistically ＂not significant＂, i.e., these elements were not thought to be significantly associated with CaO. It was also discovered that major enrichment of CaO in the finest bottom ash fractions could be advantageously used for simple separation of elements strongly associated with these fractions, mainly S and As, but also Cl or Br. Removal of5% of the finest ash particles brings about a decrease in As concentration down to 77%-80% of its original bulk ash content, which can be conveniently used e.g., when high As content complicates further ash utilization.

The monitoring,Evaluation, reporting,verification, and certification of energy-efficiency projects

In this paper, we present an overview of guidelinesdeveloped for the monitoring, evaluation, reporting,verification, and certification (MERVC) ofenergy-efficiency projects for climate changemitigation. The monitoring and evaluation ofenergy-efficiency projects is needed to determine moreaccurately their impact on greenhouse gas (GHG)emissions and other attributes, and to ensure that theglobal climate is protected and that countryobligations are met. Reporting, verification andcertification will be needed for addressing therequirements of the Kyoto Protocol. While the cost ofmonitoring and evaluation of energy-efficiencyprojects is expected to be about 5–10% of a project'sbudget, the actual cost of monitoring and evaluationwill vary depending on many factors, including thelevel of precision required for measuring energy andGHG reductions, type of project, and amount of fundingavailable.     

Algorithmen,gehirne, computer

In order to say something substantial about the fundamental limits of machines (especially of computers) and of human calculations, we must explicate the concept of algorithm. Such an explication is provided by the Turing machine. Thus, problems have been discovered which cannot be solved algorithmically. For other problems there are problem-solving procedures, but no elegant algorithms. That men are fundamentally superior to machines has not been shown as yet.
