用循环经济理论指导工业区环境影响评价

区域开发的不确定性等给区域开发的环境影响评价(REIA)提出了较高的要求。循环经济按照自然生态学的原理,形成"资源-产品-消费-再生资源"的物质闭循环的流动过程。融入循环经济理念,将弥补传统区域开发环境影响评价模式的不足,更好发挥其在项目审批及环境管理中的作用。     

Dams in the Amazon: Belo Monte and Brazil’s Hydroelectric Development of the Xingu River Basin

Hydroelectric dams represent major investments and major sources of environmental and social impacts. Powerful forces surround the decision-making process on public investments in the various options for the generation and conservation of electricity. Brazil’s proposed Belo Monte Dam (formerly Kararaô) and its upstream counterpart, the Altamira Dam (better known by its former name of Babaquara) are at the center of controversies on the decision-making process for major infrastructure projects in Amazonia. The Belo Monte Dam by itself would have a small reservoir area (440 km²) and large installed capacity (11, 181.3 MW), but the Altamira/Babaquara Dam that would regulate the flow of the Xingu River (thereby increasing power generation at Belo Monte) would flood a vast area (6140 km²). The great impact of dams provides a powerful reason for Brazil to reassess its current policies that allocate large amounts of energy in the country’s national grid to subsidized aluminum smelting for export. The case of Belo Monte and the five additional dams planned upstream (including the Altamira/Babaquara Dam) indicate the need for Brazil to reform its environmental assessment and licensing system to include the impacts of multiple interdependent projects.

无碴轨列车运行引起的环境振动影响评价

对遂渝高速铁路无碴轨道试验段客车运行引起的环境振动进行了现场实测,根据实验数据分析得知:环境振动强度随距离增大而减小,随车速增大而增大,但车厢数量对环境振动强度影响不明显;环境振动主要频率范围为30～120 Hz,距轨道距离、车速、车厢数量对振动主要频率影响不显著;在轨道两侧31.9 m处,速度超过104.7 km/h列车环境振动强度超过GB 10070-1988要求,须采取措施隔振。     

土地一级开发环境影响评价初探

衔接土地利用规划和建设项目的土地一级开发伴随着土地政策的改革而出现。目前土地一级开发环境影响评价处于起步阶段,缺乏对这项工作系统的研究。本文结合工作中的实践经验,从土地一级开发环境影响评价实施的意义、作用和评价目的等方面对土地一级开发的环境影响评价进行了论述,分析了其环境影响评价存在的问题,总结了土地一级开发环境影响评价的技术要点,并对完善土地一级开发环境影响评价制度提出建议。     

瑞士绿色水电认证对我国水电开发评估的启示

简要介绍了EAWAG"绿色水电认证"的概念、程序和标准要求,分析了我国目前水电站评估中存在的制度上、技术上的缺陷和问题,结合"绿色水电认证"的特点,论证了该认证标准在我国水电站评估中的适宜性:绿色水电认证将管理计划与生态目标有机地结合,为我国水电评估指标体系的构建提供了十分有益的参考;通过绿色电力认证额外增加的发电量作为生态投资,强调电力的生态价值,提供资金改善受影响河道的生态完整性;绿色水电认证标准中关于生态监测的数据要求,能够填补我国目前水电站生态影响评价数据的不足.     

Evaluating the use of Social Impact Assessment in the context of agricultural development projects in Iran

The utilisation of Social Impact Assessment (SIA) in Iran is analysed in terms of its policy context and its application in practice. Five case studies where SIA was employed in conjunction with Environmental Impact Assessments (EIA) for agricultural development projects are evaluated. In addition, the performance of the policy context is assessed. This research revealed that there are legal and institutional constraints to the effective functioning of SIA in Iran, and that there are deficiencies in the operating guidelines. There were serious problems associated with the way SIA was undertaken in all five case studies. Recommendations to improve the policy framework for the conduct of SIA are made. The recommendations advocate for a higher profile of SIA within legislation, for social issues to have greater emphasis in official guidelines for the conduct of EIA and SIA, and for a range of measures to increase the professionalism of SIA practice.     

建设项目环境影响的医学评价方法研究

作者在对中国我人民解放军第４７医院病建项目所产生的大气环境影响进行了医学秤价和影响，并在预测的基础上，建立了完整的环境医学影响廉政价方法，由于该评价方法完全尊循了国内现行大气环境影响评价的基本要求和程序，因此，它在今后的环境影响医学评价中净有广泛的应用。     

基于RIAM模型的生态旅游开发环境影响评价研究

RIAM (Rapid Impact Assessment Matrix)是进行环境影响快速识别的半定量评价方法,能综合考虑项目对自然环境-生物生态-社会文化-经济发展的影响,评价过程较传统评价方法更为透明公开.以武夷山生态旅游开发项目为例,应用RIAM模型进行生态环评,可以明确地表达项目的综合环境影响,使各种替代方案环境影响对比清晰明了,且还能快速判断出生态旅游开发的主要负环境影响排序.RIAM环评方法使环评过程透明,环评结果表达直观,能更好服务于环境决策和管理.     

环境影响评价机制中公众参与存在问题及对策研究

随着新环境保护法的实施,人们的环境保护意识越来越高,信息公开和公众参与的重要性也愈发凸显。对于环境保护的重要环节———公众参与,在建设项目的环境影响评价中更是体现了“民主决策”、“预防为主”的思想。随着公众对环保认识程度的加深,环境需求的提高,公众参与中一系列问题也随之产生。文章在结合实际工作的基础上,从参与者的人选及参与的方式、时机、信息公开的方式等方面剖析了公众参与存在的一些弊端,并提出了对策和措施,为中国现有的公众参与制度的完善提供了一些参考。
