能值分析理论研究述评

Studies on emergy analysis theory

能值分析是以能值为共同基准，通过综合分析评价系统的能物流、货币流、人口流、信息流，得出一系列反映系统结构和功能特征与生态经济效益的能值指标，进而评价系统的可持续发展性。由于新兴的生态经济学在理论发展和实际应用研究上迫切需要定量化的研究方法，因此能值分析就是把生态经济系统中的能物流、货币流、人口流、信息流综合起来，根据能值的相关概念和理论将各种能流换算成同一种能值，最后通过一系列评价指标对生态经济系统做出相应的评价。在目前研究中，能值分析在生态经济系统的应用已经逐渐走向成熟。本文通过全面的对国内外能值分析理论的研究做出正反面评价，进一步展望了能值分析理论的研究方向，望相关学者能对此进行更深入的研究，从而为衡量生态经济系统的可持续性提供更加完善的分析方法。

Emergy analysis is based on the emergy as a common benchmark evaluation system through a comprehensive analysis of the energy logistics, money flow, population flow, information flow, draw a series of reflecting the characteristics of system structure and function of ecological and economic benefits of emergy indicators for assessment of the sustainable development of the system. As the emerging ecological economies in the theoretical development and practical application of research, the urgent need for quantitative research methods, thus emergy analysis is making the money flow, population flow and information flow of the ecological and economic systems together, according to the relevant concepts and theories of the emergy, the all kinds of energy flow can be converted into the same emergy, at last,making the appropriate assessment through a series of assessment indicators. In the current study, the Emergy Analysis has gradually matured in the application of eco-economic system, but there are shortcomings. In this paper, a comprehensive analysis of domestic and international the theoretical study of the emergy can be made positive and negative evaluation,studying the prospects of the theory of emergy analysis research further,hoping the relevant scholars to conduct a more in--depth study to measure the eco--economic system sustainability to provide a more complete analysis.
