摘要
生态经济系统是一种最广泛阐述生态系统与经济系统之间关系的体系,重点探讨人类社会的经济行为与其所引起的资源和环境嬗变之间的关系,它是生态系统与经济系统相互交叉具有边缘性质的研究领域。生态经济系统研究的对象是复杂的生态经济巨系统,其目的是研究人类经济活动与生态环境关系及其规律,指出了人类社会子系统的存在必须依赖于生态经济系统的平衡和自调节机制。目前具有多种生态经济系统研究的方法,本文选用美国著名生态学家H.T.Odum于20世纪80年代创立的能值分析(emergy analysis)理论和方法对区域的可持续发展进行度量和评估。利用各种资源的能值转换率(transformity),将其以太阳能焦耳(Solaremjoules)为统一尺度,解决了不同类型能量之间无法进行核算问题,为我们提供了一种新的能量分析理论。
The eco - economic system is the most widely elaborate the relations between ecosystem and economic system, the emphasis of which probe into the relations between economic behaviors of human society and the changes of resources and environment rising from these behaviors. It is also a study field that the ecosystem and economic system mutual overlap and possess a marginal character. The study object is complicated and huge system of eco - economy, and the purpose is study relations between human economic activities, ecological environment and its laws, which point out that its balance and adjustable mechanism by itself have affected the existence of human society subsystem. Currently, there are varied study methods about it. The thesis chooses emergy analysis theory and methods which was created by H. T. Odum in 1980s to evaluate the regional sustainable development. Because it has worked out the question that is unable to calculate between the different type energy by using emergy transformity of various resources and making the Solar emjoules as unified criterion which provide a new emergy analysis theory.
