基于生态足迹模型的区域生态可持续性判别准则研究

针对传统生态足迹模型在区域生态可持续性评价中存在的不足,文章基于改进的"消费-产出"生态足迹模型,以可持续承载生态亏损额为评价指标,构建了区域生态可持续性判别准则,对临湘市2005-2013年的区域生态可持续性进行了计算和分析,并与传统生态足迹模型计算结果进行了比较。结果表明:(1)在研究时段内,临湘市的可持续承载生态亏损额在波动中呈增长趋势,处于生态可持续状态;(2)耕地、牧草地和水域的可利用生态承载力潜力已完全释放,而建设用地和林地的可利用生态承载力潜力并没有得到充分的利用;(3)区域生态可持续性呈现北高南低、中部最弱的趋势;(4)改进后的生态足迹模型较传统生态足迹模型在区域生态可持续性评价中的结果更全面、更符合实际。结合研究结果,对该区域的土地利用和经济发展模式提出针对性建议,为临湘市的生态可持续发展提供参考依据。

《可持续性的优势》

为什么要写这本书 现在,越来越多的人群向工商业提出承担社会和环境责任的要求,客户、投资商、企业员工、立法机构、银行、保险公司等等.企业家们对此往往说:"承担社会责任虽然是个完美的理念,但是对我们来说,最重要的是经济利润!"这表明,在促成企业遵从三重底线原则(经济、环境和社会)、履行社会责任方面,还没有令企业领导心悦诚服的案例和切实可行的方法.     

The role of academia in regional sustainability initiatives: Wales

This paper demonstrates the relative non-engagement of universities in regional sustainability initiatives through a case study of Cardiff University in Wales. It is argued that the turbulent and often complicated political and administrative context along with divergent goals and performance targets means that synergies are less readily achieved. A case study of automotive industry alternative technology new cluster development is given to illustrate the arguments. In so doing, the paper presents the view that we need to move beyond mere optimism in order to address fundamental underlying issues.     

可持续性和规划适应性的规则

这篇文章根据生态可持续性的观点,挑战当前主流规划办法,适用于法治国家并建立在现代环境法办法的基础之上.这篇文章根据全世界环境政策大规模实施不利的一般经验,讨论了环境目标的设定和实施.在此,把环境规划与自适应管理办法作比较.环境规划中至少有一些法则来源于新西兰的<资源管理法>,更多则取自法律操作化的当代环境法律理论;而自适应管理办法在实施失败或似乎很难实施的情况下,允许考虑调整环境相关目标.自适应环境规划(AEP)观念被建议作为在通过环境限度合法界定框架内最大限度地发展的同时,选择可持续性规划的一个可能的路径.这篇文章提出了5个标准,这些标准是在自适应环境规划中必须要符合的.这些标准之一涉及到规划的层次,规划的层次与其它情况一起导致这样的结论:如果海岸带规划的目标是可持续性,就不能孤立地来对待,尽管在区域一级上这样的规划可能不得不面对非常复杂的问题.     

The Automobile Industry & Sustainability

This paper summarises the contributions made to the special issue on The automobile Industry & Sustainability. Taking a life-cycle perspective, the contributions are allocated into the automotive life-cycle phases of design, manufacture (and supply chain management), use, and disposal or ‘end of life vehicle’ management. The contributions are also set into the broader context of research into the global automotive industry, and the economic, social and environmental pressures confronting the industry. In doing so, this introductory paper provides a brief assessment of the ways in which the papers in the special issue have furthered our understanding of the difficulty in achieving a sustainable automotive industry, and some of the measures that might be taken as progress towards that difficult goal.     

库里提巴市的可持续性与规划程序

可持续性是一个关于人与自然或社会与环境平衡的概念。根据自身历史、地理或社会文化背景的不同,每个人或社会对这一概念的理解也不相同。虽然在理论上缺乏一致性,但是可持续发展概念一直存在于社会的自然与人为空间适应和变化过程中,以及以生存和发展为目的的生产过程中。当涉及到城市或城市空间时,这些过程反映了一个社会认可、支配和确定保证满足基本需求范围的方式,同时确保城市随着时间的发展而生存下来。     

Sustainability and environmental enhancement in changing cirumstances

Natural environment has endured fast economic growth and population explosion sine the 20th century,which has soil erosion,land desertification,ozone layer depletion,bio-diversity reduction and persistent toxic and harmful pollutants are among the major environmental challenges.     

Sustainability and environmental enhancement in changing circumstances

Natural environment has endured fast economic growth and population explosion since the 20th century, which has brought a lot of problems. Global environmental change, soil erosion, land desertification, ozone layer depletion, bio-diversity reduction and persistent toxic and harmful pollutants are among the major environmental challenges.     

Roles of academia in regional sustainability initiatives: outreach for a more sustainable future

Institutions of Higher Education have to cope with an array of challenges in the 21st century including globalization of teaching, research and outreach activities; additionally there are dramatic increases in competition for students, staff and funding sources. Meanwhile, local and regional involvement in regional sustainable development is increasing in importance as well. This latter process is driven by the mandates from many sources for academic involvement in working on the multi-faceted issues pertaining to Sustainable Development (SD). This requires concerted action not only at the global, but also at the local and regional levels. This article provides an overview of this special issue of the Journal of Cleaner Production on the Roles of Academia in Regional Sustainable Development Initiatives. The essence of the 11 articles contained in this special issue is summarized and contextualized within the rapidly evolving academic efforts on SD. Recommendations are made of ways for academia to help their regions to make more rapid progress toward SD via involvement of their faculty, students and staff in Regional SD programs and processes.     

The roles of computer models in the environmental policy life cycle

In this article, we identify four typical roles played by computer models in environmental policy-making, and explore the relationship of these roles to different stages of policy development over time. The four different roles are: models as eye-openers, models as arguments in dissent, models as vehicles in creating consensus and models for management. A general environmental policy life cycle is used to assess the different roles models play in the policy process. The relationship between the roles of models and the different stages of the policy life cycle is explored with a selection of published accounts of computer models and their use in environmental policy-making.

墨西哥圣金廷海岸资源的可持续利用

墨西哥圣金廷作为一个地理独立系统为整体分析物质流动和社会经济约束提供了理想场所.由于园艺作物(主要是西红柿)的种植,该地区陆地部分自然资源利用主要受地下水开采制约.灌溉用水量超过补给量减去输出量差值的6倍.牡蛎养殖主导着海湾内的资源利用.牡蛎的食物由潮汐时海湾水和海洋水交换而提供.牡蛎和整个系统的呼吸量表明,当前的水产养殖水平是可持续水平的40%.提出"物质不可持续能力指数"(PhUI)来衡量最大限制性资源利用远离可持续利用水平的比例陆地为6,海湾内为0.4.在PhUI和测算经济发展的基础上,我们得出了水产养殖业比农业更可行的结论.
