物系管理与可持续发展 总被引:6,自引:0,他引:6
该文回顾德国自60年代以来,从“末端治理型”环保政策到现在提出“物系管理”的发展变化,介绍了德国环境保护工作的成功与不足。从物系管理的产生背景出发,探讨了物系管理的概念、意义、应用实践、面临的困难。此外,该文还阐明物系管理可以成为促进中国可持续发展的一个及时、有效的工具。 相似文献

Competitive forces are driving US domestic manufacturers to source parts globally, which significantly extends their supply chain and introduces new sustainability concerns. This paper addresses the situation from an operating division manager's perspective. We present an approach to packaging system assessment which considers the division manager's span of control, addresses the design of packaging and the corresponding logistics processes, and incorporates both cost and environmental impacts. A construct familiar to operations managers, the value stream map, is adapted to model material flow of both parts and packages, and an integrated material flow analysis is used as the common basis for cost analysis, a modified life cycle environmental impact analysis, and an energy consumption analysis. The framework is illustrated using a case study of a major US automaker. 相似文献

Modern urban life is characterized by the consumption of materials and energy, which are imported from all over the world
and discharge waste that in many cases has a negative impact on ecosystems far from the cities in which they consumed. Indeed,
cities cannot survive without worldwide hinterlands for resources and emissions sequestration. The ecological footprint (EF)
concept provides valuable insights into the human appropriation of resources relative to earth’s carrying capacity, and therefore
it enables us to compare human demands with nature’s supply and provides an indicator of human ecological sustainability.
An attempt was made to calculate the EF of Ra’anana, Israel as a case study, to compare the EF-value with the expected for
ecological sustainability and to emphasize the dependence on overseas ecosystems. Ra’anana, a town of 67,300 inhabitants in
the year 2002, is considered a ‘dormitory town’ with a high quality of life. The EF was calculated using mainly the component
method. The calculated EF for Ra’anana is 4.0 ha/resident which means that the required hinterland, located all over the world,
is nearly 180 times the size of the town. The town’s EF is twice the value expected for sustainability on a global scale.
We draw several scenarios in order to reduce the EF. On a national basis as well as with the town case study, electric energy,
food and waste can be reduced and in turn would have a dramatic impact on the EF.

水污染的生物自动监测 总被引:1,自引:0,他引:1
生物监测是指有规则地或连续地评价一个或多个参数,而且可以用来测定有害状态。通过对生物监测领域发展状况的描述,建议水污染质量控制系统要把生物和化学-物理信息结合起来,并根据生物监测的数据进行修正,利用水生生物来及早地警报水体中存在有毒物质,并与电子计算机设备相结合,形成早期警报毒性监测系统,提出了发展生物自动监测系统的可行性,指出它在水污染控制中将成为必要的工具。 相似文献

The Finnish approach that is starting from the basic human needs of food, housing, mobility and related lifestyles enables us to address the social dimension of sustainable development alongside the ecological and economic dimensions. In this context environmental problems cannot be resolved in isolation from people’s everyday lives, as can happen if environmental policies are based purely on emissions.But it is also worth questioning the potential for national SCP programmes in today’s global markets. Over the last ten years, domestic material flows within the Finnish economy have remained fairly constant, with gains in material efficiency cancelled out by increasing levels of material consumption. However, external material flows and the consequent environmental impacts have steadily increased, and the magnitude and environmental impacts of both imports and exports are approximately the same as for domestic flows. This means that the role of external material flows can no longer be ignored in national SCP policies.It is also important to integrate SCP with climate policies. Finland’s national climate and energy strategy is mainly based on the need to reduce CO2 emissions from energy production and industrial installations, but there is also a need for complementary actions to reduce the carbon footprints caused by private and public consumption. 相似文献
