5.12汶川特大地震灾害引起了社会和学术界对地震灾后重建规划广泛的关注。地震灾后重建规划几乎包含了当前规划领域中的所有挑战,是速度和质量兼顾、人性与理性权衡、社会经济与环境效益统一、多方博弈的过程,对灾后重建规划环评也从理论到实践层面提出了新的挑战。本文在对灾后重建规划特点进行归纳的基础上提出灾后重建规划环评相应具备的特点,即早期介入、与规划过程融合、增加灾害情景、突出规划协调性分析和应用反规划思路等特点,并进一步以《国家汶川地震灾后重建总体规划》为例说明了与灾后规划融合的环评流程、灾后规划环评的关键内容和评价思路。在对常用规划环评方法从信息成本、工作成本、客观和量化程度等原则进行评价后认为灾后重建规划环境评价中应有效利用比较评价法、GIS叠图法、生态承载力评价法等相对快捷、成熟或客观的方法。  相似文献

Impact scoping is the process of identifying important issues of a proposal and focusing the environmental impact assessment (EIA) on the high-priority issues. Although impact scoping in one form or another has been inherent to EIA for some time, documentation of its development and discussion of refinements to impact scoping processes have not been forthcoming. This article traces the development of impact scoping through time and highlights the need for such processes in EIA. A focused environmental assessment (FEA) approach to impact scoping that is suitable for implementation in an EIA is presented here and advantages of its use are delineated. FEA is a three-staged process that encourages impact scoping through progressive steps including impact identification, assessment and management planning. FEA combines a suite of EIA methods including: issues matrices, impact hypotheses, valued ecosystem components, and stakeholder participation sessions to effectively integrate impact scoping with EIA.  相似文献

Environmental threats and progressive degradation of natural resources are considered critical impediments to sustainable development. This paper reports on a participatory impact assessment of alternative soil and water conservation (SWC) scenarios in the Oum Zessar watershed, Tunisia. The first objective was to assess the impact of three SWC scenarios on key social, economic and environmental land use functions. The second objective was to test and evaluate the applicability of the 'Framework for Participatory Impact Assessment (FoPIA)' for assessing scenario impacts in the context of a developing country, in this case Tunisia. The assessed scenarios included: the originally planned SWC policy implementation at 85 % coverage of arable land of the watershed, the current implementation (70 %), and a hypothetical expansion of SWC measures to the entire watershed (100 %). Our results suggest that implementation of the SWC policy at 100 % coverage of arable land achieves the maximum socioeconomic benefit. However, if stakeholders' preferences regarding land use functions are taken into account, and considering the fact that the implementation of SWC measures also implies some negative changes to traditional landscapes and the natural system, SWC implementation at 85 % coverage of arable land might be preferable. The FoPIA approved to be a useful tool for conducting a holistic sustainability impact assessment of SWC scenarios and for studying the most intriguing sustainability problems while providing possible recommendations towards sustainable development. We conclude that participatory impact assessment contributes to an enhanced regional understanding of key linkages between policy effects and sustainable development, which provides the foundation for improved policy decision making.  相似文献

This paper provides an overview of the environmental impact of mining on viable future land use and underlines the imperative of improved environmental management and closure planning. It argues that pollution prevention, through planning for closure, can lead to cost-effective strategies for sustainable minerals development and viable future land use. This seems to be most true for greenfield sites since, generally, the earlier closure planning and pollution prevention is built into a project, the more cost-effective and environmentally benign closure will be. Further, for greenfield sites, pollution prevention techniques can be employed from the outset, at the stages of exploration and mine development, and then monitored and improved through the operation stage to closure, and can be kept in place to manage future land use.
The paper discusses how global changes in the industry, following the liberalisation of investment regimes, and mergers and strategic alliances between key firms, has, by virtue of the diffusion of new technology, led to further opportunities to prevent pollution and optimise future land use through planning for closure from the outset. The objectives and components of closure plans are also reviewed as the paper draws on case studies to highlight some of the possible constraints and challenges to pollution prevention that may be faced at the level of both public policy and corporate strategy. The article concludes by suggesting a forward-looking approach to integrated environmental management and viable future land-use planning based on a dynamic model for environmental management.  相似文献

强化空间管理是规划环境影响评价优化空间开发、促进"多规合一"的新要求。同时,探索生态空间管控体系是国土空间规划的重点任务之一。本文以长春新区发展规划为例,提出前端空间引导、后端影响调控的生态空间管理体系。前端通过生态系统评价和生态空间识别,提出生态保护红线划定建议方案,确定开发"底线"。后端通过InVEST生境质量评价技术,对生境退化度及生境质量进行空间评价,识别生境威胁源影响区域,提出优化空间布局的规划调控建议。研究表明:耕地是新区发生变化幅度最为显著的用地类型,纳入生态空间管控的用地约占16.2%。其中,15.8%的用地建议纳入生态保护红线进行管理。未来城市开发对生境有一定影响,整体生境质量平均值由0.401下降至0.328。  相似文献

The Resource Management Act, passed in 1991, has significantly revised the practice of Environmental Impact Assessment (EIA) in New Zealand. In contrast to a previous emphasis on environmental impact reports of major projects, the new requirements call for environmental impact assessment of all resource consent applications and of all regional, district and city policies and plans. This signals a change directed at incorporating environmental considerations into day‐to‐day planning decisions, with the purpose of achieving sustainable management. The paper identifies and discusses some key issues which are critical for successful integration of EIA within a planning framework.  相似文献

The Great Western Development Strategy (GWDS) is a long term national campaign aimed at boosting development of the western area of China and narrowing the economic gap between the western and the eastern parts of China. The Strategic Environmental Assessment (SEA) procedure was employed to assess the environmental challenges brought about by the western development plans. These plans include five key developmental domains (KDDs): water resource exploitation and use, land utilization, energy generation, tourism development, and ecological restoration and conservation. A combination of methods involving matrix assessment, incorporation of expert judgment and trend analysis was employed to analyze and predict the environmental impacts upon eight selected environmental indicators: water resource availability, soil erosion, soil salinization, forest destruction, land desertification, biological diversity, water quality and air quality. Based on the overall results of the assessment, countermeasures for environmental challenges that emerged were raised as key recommendations to ensure ecological security during the implementation of the GWDS. This paper is intended to introduce a consensus-based process for evaluating the complex, long term pressures on the ecological security of large areas, such as western China, that focuses on the use of combined methods applied at the strategic level.  相似文献

A resource survey and planning method for parks, reserves, and other environmentally significant areas (ESAs) is presented in the context of a holistic balanced approach to land use and environmental management. This method provides a framework for the acquisition, analysis, presentation, and application of diverse ecological data pertinent to land use planning and resource management within ESAs. Through the independent analysis and subsequent integration of abiotic, biotic, and cultural or ABC information, land areas within an ESA are identified in terms of their relative environmental significance and environmental constraints. The former term encompasses wildlife, historic, and other resource values, while the latter term reflects biophysical hazards and sensitivities, and land use conflicts. The method thus calls for a matching of an ESA's distinctive attributes with appropriate land use and institutional arrancements through an analysis of available acts, regulations, agencies, and other conservation and land use management mechanisms. The method culminates with a management proposal showing proposed park or reserve allocations, buffer areas, or other land use controls aimed at preserving an ESA's special ecological qualities, while providing for resource development. The authors suggest that all resource management decisions affecting ESA's should be governed by a philosophical stance that recognizes a spectrum of broad land use types, ranging from preservation to extractive use and rehabilitation.  相似文献
