辽宁省区域经济差异与区域协调发展的初步研究

本文利用辽宁省近年来的统计数据．通过对标准差、变异系数、离差、比率、相对发展速度等参数的计算。分析了辽宁省内各地区间的区域经济差异的总体特征和空间特征。并总结了产生区域差异的三个主要因素。即自然地理环境的差异(客观因素)、区域战略重点的转移(政策因素)以及各地区经济结构的差异。在此基础上．为辽宁省区域协调发展提出了对策与建议。     

"分裂的全球化"与人类的可持续发展

经济全球化一方面推动了世界各国的合作，另一方面拉大了发达国家与发展中国家的差距。全球化进程中这种强弱群体的分化，实质上是一个“分裂的全球化”。它给人类的可持续发展带来了极大的挑战。全球化是人类发展不可逆转的方向。同时，可持续发展是人类社会共同的目标。只有解决分裂的全球化，人类才能实现可持续发展。     

广东省土地资源可持续利用评价研究

基于广东省城市化进程中土地资源利用之特点，利用熵权技术和线性加成技术建立了广东省土地资源可持续利用的评价体系，并对广东省1992～2002年期间土地利用的基本状况进行了实证分析，研究表明：广东省土地资源利用状况从总体上看是趋好的，在经历了1992～1995年的弱可持续之后，目前已进入良性发展阶段，其经济指标和社会指标均处于良好发展势头．但资源和环境指标在2000年后呈明显下滑趋势。这应该引起政府及有关部门高度重视。     

三生共赢:可持续发展的根本目标与行为准则

明确可持续发展的行为目标。制定相应的评价准则，是可持续发展思想从理念探讨向实践操作延伸的必由之路，也是进行社会行为选择的依据。在系统分析生活、生产与生态之间的关系后，提出应将“生活水平不断提高，生产能力不断增长和生态环境不断改善”(简称“三生共赢”)作为可持续发展的行为目标和评价准则，并从理论上对这一命题进行了阐述。     

Introduction: Natural Capital, Poverty and Development

Can development occur without running down natural resources in an unsustainable way? The concept of natural capital offers a way for those with divergent views (ecologists and economists for example) to discuss this difficult question. Four aspects are examined in detail. First, the role of institutions in facilitating sustainable development is discussed, with examples from forestry. Then examples from (eco)tourism illustrate the potential – and limits – of applicability of the concept. Measurement issues for natural capital are then considered in detail. Finally, the concept is applied to agricultural strategy in fragile lands, where the tradeoff between the environment and development is likely to be most severe. Some implications for future research and policy are developed.     

Production, Consumption and the World Summit on Sustainable Development

At the World Summit on Sustainable Development (WSSD), world leaders agreed that eliminating unsustainable production and consumption is one of the three overriding objectives of sustainable development. Achieving that objective should have been a major priority for the WSSD Plan of Implementation. Increases in consumption and production over the past decade were largely responsible for the worsening environmental and social trends. Unfortunately, the negotiators of the Plan paid insufficient attention to the lessons from 10 years of discussions about the concepts, the available policies and tools and their effectiveness, the impacts of those policies on developing countries, and the political commitment of countries in an era of globalization. Despite a promising proposal for a new ten-year work programme aimed at bridging the gap implementing the Agenda 21 commitments from Rio, Summit negotiators produced barely more than a muted echo of recommendations from the past which have yet to be taken seriously enough by the world's leaders in a comprehensive intergovernmental strategy. In the ten-year review of progress to achieve sustainable production and consumption (SPAC), governments quickly skipped past the critical work of examining why things are getting worse, avoiding the task of identifying the obstacles (which in some cases were themselves) and in turn avoiding the commitment to time-bound measurable targets. If nothing else, the WSSD demonstrated that a global strategy to achieve SPAC will come not from a UN consensus of world leaders but from a strategic alliance of responsible governments, civil society and others with a vision beyond the next election cycle.     

土地健康与土地资源可持续利用

土地健康是伴随可持续发展战略的实施而兴起的一个土地资源研究方向，对土地资源可持续利用的实现有着很大的实践指导意义。本文在分析土地健康内涵的基础上，论述了土地健康与土地资源可持续利用的关系，并进而针对我国土地资源的特点，提出加强土地健康研究，促进土地资源可持续利用的主要对策措施。     

区域持续发展与地理信息系统的协调作用

环境与发展是当今人类社会所面临的两大主题,已引起各国政府和国际社会的广泛关注。持续发展代表了一种新的发展战略和我们从事经济活动的新方法。地理信息系统技术具有综合各种社会、经济和环境因素的能力,为科学决策和实现区域持续发展提供了一种强有力的工具。同时,地理信息系统为在区域持续发展中利用生态学方法、时序分析和科学决策提供了强有力的技术支持。在我国,区域持续发展已引起了越来越多的研究机构与政府部门的重视。应该注意到,实现这一目标离不开地理信息系统技术的支持。本文主要讨论地理信息系统对区域持续发展的作用和探讨建立区域持续发展的地理信息系统的理论模式。
