| 摘 要： | 1 Introduction Ecological industry is to realize the harmony de- velopment between economy and environment by planning industrial systems according to material cy- cle in the natural ecological system. It got grown rap- idly both in theories and practices since the 1990s1,2]. Many countries including China have applied indus- trial ecology to industrial practices. It is deeply recog- nized that developing ecological industry and advanc- ing on a new industrialization mode is an important way…

| Abstract: | Exergy analysis of eco-industrial systems reflects the thermodynamic characteristics of resource utilization by studying complicated material flow patterns to an industrial system. Different indicators based on exergy analysis are presented, such as system exergy depletion index, cycling ratio of material exergy, etc. which can be used to evaluate the efficiency of resource utilization and the environmental potential effect. The interrelations of these exergy indicators and their interpretation on industrial ecology are further discussed. Finally, the result of case study suggests effectiveness of exergy analysis methods and practicability of these exergy estimate indices. |
