上海世博会环境空气质量状况和原因分析

通过2001—2010年世博会同期上海市环境空气质量变化趋势和特征分析,简析上海世博会期间环境空气质量改善和世博后空气污染反弹问题的原因。结果表明,世博期间上海市环境空气质量优良率高达98.4%,为历年同期最佳;大气污染防控措施成效显著,尤其是脱硫措施实施效果明显;世博后由于季节变换、沙尘影响和监管力度减弱等因素导致空气污染有所反弹。     

通榆河南段控制单元最大日负荷估算及分配研究

以通榆河南段控制单元为研究区,利用现有的平原感潮河网区水量模型、面源污染负荷统计模型和水环境容量模型,估算研究区2010年污染物最大日负荷总量（TMDL）,并进行负荷削减和分配研究。结果表明：研究区COD、氨氮（NH3-N）90％保证率（2004年）下的水环境容量分别为7．76万t,0．37万t;xCN2010年污染物入河量,COD、NH3-N的最大年负荷分别为1．99万t,0．28万t。在研究区涉及的各县市中,海安、姜堰、东台是负荷削减的重点区域;对于不同的污染源,城镇生活点源和农业面源是研究区污染物总量控制的关键。     

中国银行业与中国的碳金融发展

本文介绍了碳金融的定义以及中国构建完善碳金融体系的背景,指出我国的CDM市场虽然是全球最大的CDM市场,但碳金融还处于起步阶段,缺乏国际CERs定价权,CDM项目存在巨大的风险,这些问题亟需解决。中国的银行业作为中国金融机构的主要组成部分,在构建完善的碳金融市场上起到了十分关键的作用。分析了目前中国银行业参与碳金融的现状及存在的问题,提出了中央银行和中国商业银行介入碳金融的方法。中央银行应与商业银行相互配合使中国的碳金融市场尽快发展和完善。     

Practical and ethical considerations of agricultural research assistance for the Third World

The right to eat and to an adequate standard of living for everyone motivates agricultural research assistance to developing countries with the primary objective of assuring sufficient food supply. This article focuses on aspects of food production and related agricultural research with specific examples from animal production. It discusses ethics of agricultural research in light of the utilitarian theory and compares livestock production in developing and developed countries. Major reasons for low outputs of animal production in developing countries are identified, and the potential for increasing the productivity of original, extensive production systems is evaluated. The article reviews the current status of biotechnology in developing countries and discusses several advanced animal technologies. The conclusions emphasize the need to involve local professionals in all phases of research and technology transfer in developing countries, avoidance of research that may worsen the situation of the recipients, sustainability of production systems, and the need for detailed assessment of potential impacts of technology on recipients.     

沈阳市利用国家开发银行贷款推动环保产业发展浅析

沈阳市政府从2005年开始到2007年11月末，通过沈阳恒信国有资产经营有限公司融资平台从国家开发银行融入贷款资金近295．17亿元用于老工业基地改造。据统计，共有139亿元开发银行贷款用于沈阳市“沈阳西部污水治理工程（西部细河改造）”等环保工程、环境治理等项目，占全市开行贷款总数的47％。项目的实施改善了我市的生产和生活环境，对提高沈阳市的城市品位，完善城市功能起到了积极的促进作用。但由于部分项目前期准备工作不充分、管理主体缺位、二级平台不健全、配套资金筹措不及时等原因，影响了项目进展和资金有效使用，为提高沈阳政府融资信誉，有关部门应通过建立我市开行贷款项目的储备制度、加强二级平台建设、多渠道筹集配套资金、建立有效的防范债务风险的机制等项措施，努力防范和化解财政风险。     

Invisible Losses and the Logics of Resettlement Compensation

The necessity of compensating people negatively affected by conservation and other development projects has been widely acknowledged. It is less widely acknowledged that because conventional compensation assessments focus on material resources and their economic equivalents, many important losses incurred by resettlers are invisible to project authorities. Through ethnographic observations and interviews, we documented losses identified by people facing resettlement from Mozambique's Limpopo National Park. We also examined resettlement planning documents to determine why decision makers’ assessments of natural resource use and value neglect losses residents identified as critical. Identifying, preventing, and mitigating invisible losses in resettlement planning necessitates a better understanding of intangible benefits residents derive from resources, which are often as or more important than their readily apparent material properties. These benefits include but are not limited to decision‐making authority linked to owning land versus having the use of fields; ancestral identity and social belonging linked to gravesites; the importance of tree roots that provide a powerful sense of security because they suppress hunger in periods of scarcity; and the importance of people's location within social networks and hierarchies as they determine the benefits versus risks that will be incurred through resettlement.

关于世行贷款农业灌溉项目环境影响评价问题的讨论

农业灌溉工程建设是我国第十二个五年规划纲要中提出的全面加强农田水利建设工作的重要组成部分。随着越来越多农业灌溉项目的兴建及我国环境影响评价制度的发展,农业灌溉项目的环境影响评价也在不断发展和完善中。本文根据世行贷款项目——中国四川武都农业灌溉项目环境影响评价实践和工作经验,分析总结了世界银行及我国在农业灌溉项目环境影响评价工作方面的特点和要求,其中世界银行在有些方面,如评价等级、公众参与等与国内环评要求基本一致,而有些方面,如回顾性评价、替代方案分析、累积性影响分析、环境管理计划、移民安置行动计划、病虫害管理计划等在国内环境影响评价中尚未引起足够的关注或与世界银行要求存在较大差异,值得我国环评工作参考和借鉴。     

上海世博会突发环境事故应急预案系统研究探讨

针对中国2010年上海世博会可能发生的各类突发环境事故,提出应集成运用数据库、GIS、数学模型、专家系统等多种技术手段,特别是提出采用CBR技术,开发世博会突发环境事故应急预案系统。以提高世博会运行管理时期对各类突发环境事故的预防和处理处置能力;指出环境事故应急预案的主要研究工作应包括应急预案的种类、内容、支撑技术体系,以及应急预案系统的规划、建设与运行管理等;给出了需要解决的关键技术问题和系统开发方案。     

Quoting “the Environment”: Touchstones on Earth

Media influence public awareness through agenda setting and framing of news by selecting what is published, how frequently and through what frames. This content analysis compares portrayals of climate change based on political ideology of the media. It examines daily coverage of climate change in Santiago, Chile by the conservative, El Mercurio, newspaper, and the liberal, La Nación. Twenty percent of the 1,628 articles published in 2003, 2005, and 2007 which included the words “cambio climático” (climate change) or “calentamiento global” (global warming) were analyzed for frequency, content, images, and frames. The liberal newspaper published twice as many articles that were twice as long, with four times as many illustrations about climate change. They presented more thematic and diverse frames than the conservative newspaper. Government sources and conflict frames dominated both newspapers, reflecting some similar maturation processes of climate change coverage found in Europe, the United States, and elsewhere.
