构建人类命运共同体、应对气候变化与生态文明建设

全球气候变化给人类社会文明带来严峻挑战,需要人类社会采取共同措施和行动积极应对。应对全球气候变化是当今世界最能体现人类共同命运的领域,深度参与并积极推动全球气候治理体系改革和建设是中国推动构建人类命运共同体的重要实践,也是生态文明理论和实践的重要方面。应对气候变化是我国生态文明建设的重要内容和内在要求;以共同价值理念构建人类命运共同体,凝聚各国力量携手合作应对全球气候变化,是全球生态文明建设和构建人类命运共同体的具体实践,也为应对全球气候变化提供了良好载体和国际平台。文章通过分析可知,应对气候变化、生态文明建设与构建人类命运共同体三者之间,呈现出相互促进、和谐共生的"三位一体"特征;人与自然共生的生命共同体是前提条件,人类的任何实践活动都要以自然生态系统为基础和前提;人类命运共同体在整合各国力量方面,为生态文明建设提供了社会基础;生态文明包容各国文明,凝聚价值共识,成为生命共同体和人类命运共同体的价值导向。中国倡导人类命运共同体理念,是全球生态文明和人类命运共同体的积极倡导者、推动者和践行者,既为应对全球气候变化提供了价值基础,也提供了强有力的实践支撑;应对气候变化是全球生态文明建设和人类命运共同体构建的生动实践。因此,加强生态文明建设和构建人类命运共同体,为全球应对气候变化提供了理论基础和国际平台,也将为全球可持续发展贡献中国智慧和中国案例。     

Energy efficiency and appliance’s characteristics considered prior to purchase: Differences and similarities between the United Kingdom,Germany, Portugal,Greece, Poland,Spain and Italy

This article reports country differences in the consumer’s most considered characteristics when choosing electrical appliances, including but not restricted to the energy efficiency aspect. A survey was performed to store customers from 7 countries: the United Kingdom; Germany; Portugal; Greece; Poland; Spain; Italy. Results showed consistency between countries in the top three characteristics considered: cost; quality; and a balance between price and quality. Differences were found for reported environmental attitudes and behaviours, purchase motives, and store employees evaluation. The results may support national policies and store level energy efficiency interventions. Specifically, they can provide input for store employee’s training, in persuading customers towards the purchase of energy efficient appliances.     

土地利用生态服务价值指标体系评估结果比较研究

生态系统服务价值评估越来越受到学术界关注。针对当前生态服务价值评估方法、指标体系和评估效果较多的实践,通过文献归纳,对国内外土地利用生态服务价值评价方法、指标体系及其系数进行了梳理、分类和评价,将指标体系分为Costanza和谢高地两大类,并将谢高地指标体系分为价值当量、价值系数和区域修正。以辽宁省2005、2010年土地利用数据为案例,运用Costanza价值系数、谢高地两个版本价值当量、两个版本价值系数的区域修正,分别核算了案例区生态系统服务价值及变化,并比较评价结果。研究得出Costanza价值系数应用于中国实践时评估结果显得偏低,谢高地2002版的价值当量和2002版的价值系数区域修正结果最接近平均值,相对较为可取,2007版的价值系数区域修正评估结果也较为接近均值但略低,2007版的价值当量评估结果总体偏高。研究结果有利于指导土地利用生态服务价值评估指标体系选取。

Experimental study of recycling lightweight concrete with aggregates containing expanded glass

The focus is on the issue of waste management when constructing and recycling lightweight concrete (LWC) with aggregates containing expanded glass. The paper analyses the recycling of concrete from lightweight aggregates, and on the important issue of environmental and waste management. The characteristics of recycling LWC such as density, compressive strength and thermal conductivity are investigated, and compared with normal existing concrete from lightweight aggregates. The results indicate that it is possible to recycle lightweight concrete construction waste. The described method shows great possibilities for increasing the use of construction waste materials from LWC containing expanded glass, in order to benefit from better use of the available capacity from existing construction waste. The characteristics of density, compressive strength and thermal conductivity from the new recycled material were compared with normal existing concrete from lightweight aggregates, such as changes in dependency on the type and parts of waste as well as its new binding components. Thus, a new recycled material has been created with new characteristics of density, compressive strength and thermal conductivity, which is conform to the compressive strength class and rules on heat protection and energy efficiency use in buildings (SI OJ RS No. 42/2002). Laboratory density, compressive strength, and thermal conductivity tests results showed that LWC can be produced by the use of waste LWC with aggregates containing expanded glass. However, the use of waste LWC with aggregates containing expanded glass seems to be necessary for the production of cheaper and environmentally friendly LWC.     

中美职业安全健康法对比

通过对中美职业安全健康立法目的和背景的考察,对比分析职业安全健康法涉及的6项具体内容,即体例结构、适用范围、监管方式、监管体制、教育与培训、法律责任,并指出国情不同是造成中美职业安全健康法立法巨大差异的原因之一。经对比分析,可得出几点结论:从中国国情出发,走逐步完善的职业安全健康立法路径,建立独立的职业安全健康法律体系,是我国安全生产的治本之策;对从业人员的职业安全健康保护具有首要性,须明晰保护劳动者的上层法律要求,《安全生产法》并不能代替《职业安全健康法》;完善中国职业安全健康法律制度须走一体化整合的道路。     

中国21世纪城市供水新概念--分质供水

结合我国城市一直使用的统一给水方式已与当前水资源紧缺,用水多样化,人们饮用水质质化的状况极不适应的情况,提出对传统的给水方式进行改革的最适宜方式是分质供水。     

粪大肠菌群多管发酵测定法的改进研究

对地表水和废水中粪大肠菌群目前通用的多管发酵检测方法进行优化。将水样接种至乳糖蛋白胨培养液后,在44.5℃±0.5℃培养箱中培养24h记录结果,并与优化前的方法进行对比。结果表明,改进后的方法在时间上比改进前节省了约24~48小时,但两者在结果上无统计学意义的差别。多管发酵改进法可以用于地表水和废水中粪大肠菌群的检测。     

企业安全管理体系标准模式的比较研究

采用对比分析法和实证分析法,对当前国内外流行的企业安全管理体系标准模式及其评价方法进行比较研究,旨在把握诸多标准模式的原则、路径、结构、方法和共性特征及其可以发挥的具体优点,将研究的标准模式的评价方法归纳为两大类即体系认证审核法和综合考评打分法,并对两类评价方法的优缺点进行剖析。体系认证审核法的优点是过程方法、符合性及抽样,考评打分法则提供了安全绩效准则。对吸收融合两类评价方法的优点形成综合性评价方法的途径和方式进行了探讨,为企业建立有效、适用的安全管理体系提供了依据。     

中日多氯联苯（PCBs）废弃物回收处置技术比较

自上世纪80年代伊始,我国含有多氯联苯的电力电容器等相继进入报废阶段,许多地区采用回收后山洞贮存、地下封存等方式处置,而其他处置方式在我国尚处于初级试验阶段。日本一些企业所采用的多氯联苯处置技术,值得我们学习和借鉴。
