Even though “sustainable development” seems to have emerged as the development paradigm of the 1990s, a great deal of vagueness
still surrounds the meaning, definition, and theoretical underpinnings of the concept. There is also a general lack of emphasis
on the spatial dimension of sustainable development when developing relevant conceptual or environmental accounting frameworks.
In clarifying the concept, this article proposes a definition that explicitly incorporates the temporal as well as the spatial
dimension of sustainability. It also develops a logically consistent conceptual framework for the analysis and evaluation
of sustainable development, following a spatial systems approach. Five interconnected aspatial subsystems or subsets of a
spatial system are identified and their respective operational dimensions discussed. A proposed composite index calleddegree of stainable development (DSD) and its five component indicators are also outlined. The difficulties involved in operationalizing the DSD measure
and the conceptual framework are noted, and the various tasks that need to be undertaken in this regard are specified. It
is concluded that future research utilizing the proposed conceptual framework should not only foster the development of appropriate
methodologies for the comparative evaluation of sustainable development at global, national, or regional scales, but also
offer insights to appropriate decision makers at various levels regarding available options and alternative actions for the
healthy development of their respective societies. 相似文献

从自然资源和生态环境的公共性出发,认为以经济建设为中心的政策选择,促成了以淡视生态环境为前提的均衡策略,让经济发展与环境保护之间形成"坏"的纳什均衡,而新常态能够为经济发展和环境保护之间达成好的纳什均衡提供了改革保障、法制保障和经济保障,因此,新常态下的生态文明建设能够解套环境保护的"囚徒困境",最重要的任务是借助政府这一外力制定新的"游戏规则",以打破原有的"纳什均衡",通过建立健全环境成本内部化的政策措施和生态补偿机制、改革政绩考核机制实现对绿色发展的激励等措施,推进经济发展与环境保护之间达成理想的"纳什均衡"。 相似文献

Abstract Land degradation is one of the serious environmental problems that can lead to poverty, and is especially prominent in eco-fragile areas in developing countries and increases the risk of environmental safety. North Hebei Province belongs to an ecologically fragile region in North China, which has great impact on the eco-safety of Beijing and Tianjin. Using Landsat TM data and GIS, this paper evaluates land degradation in North Hebei province of China from the the 1960's to 1987 and 2000. Land use/cover change pattern from 1987 to 2000, its regional difference and forest change characteristics will also be analyzed; soil erosion intensity and arable land suitability were also evaluated. Results revealed that land use/cover pattern in this study area did not change greatly from 1987 to 2000. The structure and function of regional land ecosystem was at a level of local improvement and integral deterioration. Land above medium soil erosion intensity reached 21 percent, which was also the area with a serious soil erosion and land degradation problem. Soil erosion and land degradation intensity of grassland was the biggest. For the present arable land, the proportion of high suitability was 13 percent. 相似文献
