环境影响评价是环境质量评价的一个分支,在欧美等工业发达国家中发展十分迅速,已成为环境科学中的“热门”。近年来,我国各级领导部门对开展此项工作也十分重视。化工部颁发的《化学工业环境保护管理暂行条例》第十八条也明确规定“……凡没有提出环境影响报告,未经环保部门和其他有关部门审查批准的项目,不得列入各级基建计划”。为了使读者更好地了解环境影响评价工作,推动并加快此项工作的开展,本刊从本期起,开设该专题讲座,约请北京师范大学地理系王华东同志撰稿,结合化学工业环境影响评价工作的特点,从理论和实践两方面作了比较系统的阐述。该讲座共分四讲: 第一讲、环境影响评价的意义及其程序; 第二讲、环境影响评价的内容; 第三讲、环境影响评价的方法; 第四讲、我国的环境影响评价。 相似文献

Environmental and economic assessment methods for waste management decision-support: possibilities and limitations. 总被引:1,自引:0,他引:1
G?ran Finnveden Anna Bj?rklund Asa Moberg Tomas Ekvall 《Waste management & research》2007,25(3):263-269
A large number of methods and approaches that can be used for supporting waste management decisions at different levels in society have been developed. In this paper an overview of methods is provided and preliminary guidelines for the choice of methods are presented. The methods introduced include: Environmental Impact Assessment, Strategic Environmental Assessment, Life Cycle Assessment, Cost-Benefit Analysis, Cost-effectiveness Analysis, Life-cycle Costing, Risk Assessment, Material Flow Accounting, Substance Flow Analysis, Energy Analysis, Exergy Analysis, Entropy Analysis, Environmental Management Systems, and Environmental Auditing. The characteristics used are the types of impacts included, the objects under study and whether the method is procedural or analytical. The different methods can be described as systems analysis methods. Waste management systems thinking is receiving increasing attention. This is, for example, evidenced by the suggested thematic strategy on waste by the European Commission where life-cycle analysis and life-cycle thinking get prominent positions. Indeed, life-cycle analyses have been shown to provide policy-relevant and consistent results. However, it is also clear that the studies will always be open to criticism since they are simplifications of reality and include uncertainties. This is something all systems analysis methods have in common. Assumptions can be challenged and it may be difficult to generalize from case studies to policies. This suggests that if decisions are going to be made, they are likely to be made on a less than perfect basis. 相似文献
