生态经济持续性的度量和趋势预测——以甘肃武威市为例

应用生态占用模型,对武威市生态经济的可持续性进行了评价。对武威的生物资源、能源资源和制成品资源消费的生态占用的计算结果表明,1999年武威市人均占用生物生产性空间为1.589423hm₂,调整后的武威实际生产空间供给为0.856876hm₂/人。1999年武威生态赤字0.73254hm₂/人。对于世界56个国家和地区的人均生态占用和人均GDP数据进行分析,认为二者高度相关。用幂指数模型进行趋势拟合,具有较好的拟合优度和理论一致性。武威生态占用处于强的扩张时期,到2015年,人均生态占用将会达到2.60142hm₂/人,而当年实际生态承载力阈值预测值为1.0657hm₂/人。人均生态赤字扩大到1.5357hm₂/人。生态经济系统的运行是以过度消耗自然资本为代价的。

中国米质气候资源的地域分布

稻米品质受着气候条件的明显影响。在我国不同地域，米质气候资源各不相同，对米质的影响也各具特色，总的趋势是，北方优于南方；西部优于东部；晚茬口水稻优于旱茬口；在地形复杂地区，米质气候资源还具有垂直地带性结构。我国丰富的米质气候资源为各种类型优质米的生产创造出优越的环境条件。     

Concurrency: a system design approach to environmental management and sustainability

The lessons of history indicate that mismanagement of natural resources and the environment often leads to potentially adverse consequences.The increasing interest in economic development,particularly in the developing countries of the world coupled with increasing population pressures and the globalization of economic activity is placing noticeable stresses on the ultimate sustainability of both human and environmental systems.Sustainable development is not a new concept.It has been an area of concern for different elements of society for some time.Yet efforts to understand the implications of sustainable development have not,until recently,been formalized.We have focused singularly on economic development and environmental quality as if they were mutually exclusive.This paper focuses on the concept of concurrency as both a conceptual framework and practicable method of understanding and implementing the ecology and economy of sustainability.     

Environmental principles applicable to supply chains design and operation

In this paper we deal with the problem of identifying environmental principles for the design and operation of supply chains. The operations that are included in supply chains are briefly described along with the approaches that are applied in order to improve their environmental performance. A background of environmental principles for achieving eco-efficiency and building of environmentally friendly organizational systems is presented and emphasis is put on the application of such principles “from cradle to grave”. Then, environmental principles applicable to particular objects of logistics networks planning are identified and commented upon. In addition, selective case studies from the literature, which show the applicability of the formulated principles and their relevance to practice, are discussed. The paper concludes with some remarks regarding the benefits for companies and societies, in general, that occur as a result of the application of the formulated principles.
