以城市综合交通规划环境影响评价中大气环境影响预测为例,分析了战略环境评价(SEA)中环境影响预测的特点,提出了SEA中应用空气质量模型的基本原则。在此基础上,对现有的空气质量模型(主要包括箱模式、高斯模式、拉格朗日模式和欧拉型数值模式)分别讨论了模型的时空尺度、所描述的环境要素和因子、模型的复杂性和输入数据、模拟区的下垫面特征在城市综合交通规划环境评价中的适用性。  相似文献

Strategic minerals’ is an ambiguous term. The objective of this article is to explore the major and competing usages of this essentially contested concept, with particular attention being paid to the relevant usages for both scholarly and policy-making purposes. The author examines two opposing definitional tendencies, which he labels ‘restrictionist’ and ‘broad-interpretationist’, and concludes that despite great merit in the arguments of those who would restrict the usage of the term strategic minerals, the concept itself will continue to be interpreted differently by minerals analysts.  相似文献

A growing body of research recommends interaction between managers and stakeholders to improve natural resource management decisions. While formative stakeholder research and summative evaluations of communication efforts have been well-studied, less research has included formative evaluations comparing managers and stakeholders to inform communication efforts. This study applies the communication concept of coorientation to the case of deer management on open-space lands owned by Cornell University and develops an approach to coorientation analysis for use with small decision-making teams. Mail surveys were used to assess the level of agreement and accuracy between decision makers and residents of nearby communities. Decision makers and residents varied in the topics for which they accurately predicted each other's responses; these differences have implications for approaches to communication. This study also illustrates the utility of coorientation research to reveal areas of difference within the decision-making team, as well as with the public.  相似文献

This paper presents the results of research which evaluated the performance of strategic environmental assessment (SEA) practice in South Africa in order to develop understanding of how SEA functions within a developing country with a voluntary SEA system. The research applied a combination of methods in a mixed research strategy, including a macro level survey of the SEA system together with case study reviews exploring micro level application. Three main ‘system features’ emerged, namely expansion of voluntary practice, diversity in practice and general ineffectiveness. The results also highlight a number of ‘application features’ such as a lack of focus due to an inability to deal with the concepts of ‘sustainability’ and ‘significance’, as well as poor understanding and integration with decision-making processes. Moreover, it emerged that none of the case studies seem to have conducted an ‘assessment’ per se, but rather provided a framework for strategic decision-making. The paper puts forward a number of interrelated explanations for these system and application features. In a parallel to the fable of the ‘emperor's new clothes’, SEA in South Africa appears to be regarded as the answer to all environmental problems, whilst being ineffective in practice.  相似文献

The benefits of strategic environmental considerations in the process of siting a repository for low- and intermediate-level radioactive waste (LILW) are presented. The benefits have been explored by analyzing differences between the two site selection processes. One is a so-called official site selection process, which is implemented by the Agency for radwaste management (ARAO); the other is an optimization process suggested by experts working in the area of environmental impact assessment (EIA) and land-use (spatial) planning. The criteria on which the comparison of the results of the two site selection processes has been based are spatial organization, environmental impact, safety in terms of potential exposure of the population to radioactivity released from the repository, and feasibility of the repository from the technical, financial/economic and social point of view (the latter relates to consent by the local community for siting the repository). The site selection processes have been compared with the support of the decision expert system named DEX. The results of the comparison indicate that the sites selected by ARAO meet fewer suitability criteria than those identified by applying strategic environmental considerations in the framework of the optimization process. This result stands when taking into account spatial, environmental, safety and technical feasibility points of view. Acceptability of a site by a local community could not have been tested, since the formal site selection process has not yet been concluded; this remains as an uncertain and open point of the comparison.  相似文献

The first phase of noise mapping and action planning in Ireland, in accordance with EU Directive 2002/49/EC, is now complete. In total this included one agglomeration, one airport and approximately 600 km of major roads outside the agglomeration. These noise maps describe the level of noise exposure of approximately 1.25 million people. The first phase of noise mapping was dealt with by five noise mapping bodies while 26 action planning authorities were involved in the development of the associated action plans. The second phase of noise mapping, due to be completed in 2012, sees a reduction in the defined thresholds describing the required agglomerations, roads and railways that have to be mapped. This will have a significant impact on the extent of mapping required. In Ireland this will result in an increased number of local authorities being required to develop strategic noise maps for their area along with the further development of associated action plans. It is appropriate at this point to review the work process and results from the first phase of noise mapping in Ireland in order to establish areas that could be improved, throughout the noise mapping project. In this paper a review of the implementation procedures focussing on (dominant) road traffic noise is presented. It is identified that more standardisation is needed and this could be achieved by the establishment of a national expert steering group.  相似文献

Multi-criteria analysis (MCA) is a family of decision-making tools that can be used in strategic environmental assessment (SEA) procedures to ensure that environmental, social and economic aspects are integrated into the design of human development strategies and planning, in order to increase the contribution of the environment and natural resources to poverty reduction. The aim of this paper is to highlight the contribution of a particular multi-criteria technique, the analytic hierarchy process (AHP), in two stages of the SEA procedure applied to water programmes in developing countries: the comparison of alternatives and monitoring. This proposal was validated through its application to a case study in Brazilian semi-arid region. The objective was to select and subsequently monitor the most appropriate programme for safe water availability. On the basis of the SEA results, a project was identified and implemented with successful results. In terms of comparisons of alternatives, AHP meets the requirements of human development programme assessment, including the importance of simplicity, a multidisciplinary and flexible approach, and a focus on the beneficiaries' concerns. With respect to monitoring, the study shows that AHP contributes to SEA by identifying the most appropriate indicators, in order to control the impacts of a project.  相似文献

Since the Law of the People's Republic of China on Environmental Impact Assessment was enacted in 2003 and Huanfa 2004 No. 98 was released in 2004, Strategic Environmental Assessment (SEA) has been officially being implemented in the expressway infrastructure planning field in China. Through scrutinizing two SEA application cases of China's provincial level expressway infrastructure (PLEI) network plans, it is found that current SEA practice in expressway infrastructure planning field has a number of problems including: SEA practitioners do not fully understand the objective of SEA; its potential contributions to strategic planning and decision-making is extremely limited; the employed application procedure and prediction and assessment techniques are too simple to bring objective, unbiased and scientific results; and no alternative options are considered. All these problems directly lead to poor quality SEA and consequently weaken SEA's effectiveness.  相似文献
