限制开发区可持续发展问题关系到主体功能区战略的实施。选取我国主体功能区规划中确定的限制开发区——吉林省抚松县作为研究样本,通过构建可持续发展指标体系,借助物理学中的容量模型,对其经济系统和生态环境系统的时序动态耦合度进行评价。结果表明:(1)各系统序参量总体呈现上升趋势,抚松县两个子系统内部结构正逐步向协调可持续方向调整,但经济发展滞后于生态环境建设,生态环境对抚松县经济发展具有导向和主宰作用。(2)从各系统的耦合度来看,整体呈现上升趋势,从失调阶段向勉强协调阶段过渡,但耦合水平偏低,同时耦合协调度时序变化表现出明显的阶段性特征。基于上述研究结果,从产业、生态、城镇化、生态环境建设等五大方面提出了具体建议。 相似文献

A Multiattribute Index for Assessing Environmental Impacts of Regional Development Projects: A Case Study of Korea 总被引:1,自引:0,他引:1
Evaluating environmental impacts has become an increasingly vital part of environmental management. In the present study,
a methodological procedure based on multiattribute utility theory (MAUT) has been applied to obtain a decision-maker's value
index on assessment of the environmental impacts. The paper begins with an overview of MAUT. Next, we elicited strategic objectives
and several important attributes, and then structured them into a hierarchy, with the aim of structuring and quantifying the
basic values for the assessment. An environmental multiattribute index is constructed as a multiattribute utility function,
based on value judgements provided by a decision-maker at the Korean Ministry of Environment (MOE). The implications of the
results are useful for many aspects of MOE's environmental policies; identifying the strategic objectives and basic values;
facilitating communication about the organization's priorities; and recognizing decision opportunities that face decision-makers
of Korea. 相似文献

Preliminary surveys are used to prioritize between contaminated sites to select those to be investigated more thoroughly. The data-gathering steps are almost identical between countries; however, the assessment procedures differ significantly. In this study, we have investigated 21 contaminated sites assessed as belonging to the high-risk or the very high-risk class using the Swedish Methods for Inventories of Contaminated Sites (MICS). We then applied the US Preliminary Assessment (PA) method to the same sites and compared the results and conclusions from the two screening procedures. In both cases, all sites were recommended for further investigation and the two approaches seem to corroborate one another; however, the PA assessment scores and the preliminary MICS classifications did not correlate. The results obtained with the PA method were easier to explain than the final MICS classification. The PA method also seems more transparent and easier to standardize, although objections could be made regarding the weighting scheme, because the outcome in this study was entirely dependent on the surface exposure pathway. However, to examine this in greater detail, it is necessary to include sites with less contamination: The importance of preliminary surveys in the overall risk management process gives a strong motivation for such an evaluation. Generally, the lack of research and scientific support for the various assessment procedures in use suggests that there is a need for method development, standardization, and validation. 相似文献

It has long been suggested that environmental assessment has the potential to contribute to sustainable development through
mechanisms above and beyond informing design and consent decisions, and while theories have been proposed to explain how this
might occur, few have been subjected to rigorous empirical validation. This research advances the theoretical debate by building
a rich empirical understanding of environmental assessment’s practical outcomes, from which its potential to contribute to
sustainable development can be gauged. Three case study environmental assessment processes in England were investigated using
a combination of data generated from content analysis, in-depth interviews, and a questionnaire survey. Four categories of
outcomes are delineated based on the research data: learning outcomes; governance outcomes; attitudinal and value changes;
and developmental outcomes. The data provide a robust critique of mainstream theory, with its focus on design and consent
decisions. The article concludes with an examination of the consequences of the context-specific nature of environmental assessment
practices in terms of developing theory and focusing future research. 相似文献

为满足快速增长的电力需求,缓解传统化石能源紧缺及其所伴随的大气污染问题,发电过程中几乎不产生常规大气污染物的核电逐渐成为我国重要的能源战略选择。但是,由于核电站在运行过程中,特别是发生重大核事故时,产生的放射性物质可能对健康造成负面影响,发展核电仍然存在较大的争议和阻力。在此背景下,需要构建科学、完善的核电风险评估与管理体系,以保障我国的核电行业健康、有序发展。在对国内外核电风险评估研究现状进行系统梳理的基础上,分析其对核电风险管理的意义,提出了我国未来构建核电风险评估与管理体系的建议。 相似文献

A paradigm for ecological risk assessment 总被引:6,自引:0,他引:6
Joshua Lipton Hector Galbraith Joanna Burger Daniel Wartenberg 《Environmental management》1993,17(1):1-5
The 1983 National Academy of Sciences paradigm for conducting human health risk assessment is considered with respect to ecological
risk assessment. This four-step paradigm fails to capture key intrinsic differences between the two types of analysis, specifically:
identity of risk targets and receptors; identity of the appropriate level of ecological organization at which the risk is
expressed; variability of endpoint with respect to risk receptor; and the existence ofrisk cascades through ecological feedback loops. We propose an alternative paradigm that includes a preliminary step,receptor identification, in which chemical partitioning is combined with a conceptual model of the ecosystem to identify appropriate risk targets.
In addition, we propose formal inclusion ofendpoint identification and explicit consideration of risk cascades in arelationship assessment in which interactive feedback loops are considered in an iterative process. The proposed paradigm preserves the steps of
hazard identification, exposure assessment, dose-response assessment (renamedresponse assessment) and risk characterization, although specific modifications are recommended. 相似文献

Some countries, including Taiwan, have adopted strategic environmental assessment (SEA) to assess and modify proposed policies,
plans, and programs (PPPs) in the planning phase for pursuing sustainable development. However, there were only some sketchy
steps focusing on policy assessment in the system of Taiwan. This study aims to develop a methodology for SEA in Taiwan to
enhance the effectiveness associated with PPPs. The proposed methodology comprises an SEA procedure involving PPP management
and assessment in various phases, a sustainable assessment framework, and an SEA management system. The SEA procedure is devised
based on the theoretical considerations by systems thinking and the regulative requirements in Taiwan. The positive and negative
impacts on ecology, society, and economy are simultaneously considered in the planning (including policy generation and evaluation),
implementation, and control phases of the procedure. This study used the analytic hierarchy process, Delphi technique, and
systems analysis to develop a sustainable assessment framework. An SEA management system was built based on geographic information
system software to process spatial, attribute, and satellite image data during the assessment procedure. The proposed methodology
was applied in the SEA of golf course installation policy in 2001 as a case study, which was the first SEA in Taiwan. Most
of the 82 existing golf courses in 2001 were installed on slope lands and caused a serious ecological impact. Assessment results
indicated that 15 future golf courses installed on marginal lands (including buffer zones, remedied lands, and wastelands)
were acceptable because the comprehensive environmental (ecological, social, and economic) assessment value was better based
on environmental characteristics and management regulations of Taiwan. The SEA procedure in the planning phase for this policy
was completed but the implementation phase of this policy was not begun because the related legislation procedure could not
be arranged due to a few senators’ resistance. A self-review of the control phase was carried out in 2006 using this methodology.
Installation permits for 12 courses on slope lands were terminated after 2001 and then 27 future courses could be installed
on marginal lands. The assessment value of this policy using the data on ecological, social, and economic conditions from
2006 was higher than that using the data from 2001. The analytical results illustrate that the proposed methodology can be
used to effectively and efficiently assist the related authorities for SEA. 相似文献
