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.

基于生态足迹模型的安徽省可持续发展评估

本文以安徽省及其所辖区市2003年的统计数据为基础,应用Wackernagal的生态足迹模型对其可持续发展能力进行了生态足迹计算和分析,结果表明2003年安徽省人均生态足迹为1.2907hm2,生态赤字为0.8624 hm2;分区计算结果表明大部分区市的生态足迹超过生态承载能力.     

Influence of new town development on the urban heat island - The case of the Bundang area

Five new towns have been developed around the Seoul metropolitan area since 1996. However, these new towns generate lots of traffic and related problems in the areas including those new towns and Seoul as a result of increases in population and a lack of ecological-self-sufficiency. Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 198.5 to 1999 rapidly developed which showed a difference of mean temperature above 2.0. Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be 4.5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.

新时期我国环境问题的思考

一、新时期环境保护面临的问题党的十一届三中全会，全党把工作重点由“以阶级斗争为纲”转移到以经济建设为中心的轨道上来。1992年邓小平南巡讲话，把中国的发展推到一个新的高度。中国的经济发展驶入了快车道，既不可避免地带来了难以预料的环境问题，同时也为环境污染防治提供了必要的物质基础。总之，改革开放二十年，我国的经济、社会发生了巨大变化，总的是生产力得到极大发展，综合国力得到极大加强，同时出现不少新情况，也带来了不少环境问题。在推进社会主义市场经济体制建立的过程中，资源按社会需求、经济规律流向，有利于经济…
