| 摘 要： | 论述了国际生态学最新发展的能值（Emergy）分析方法与原理，并与能量分析作比较研究，任何产品或劳务形成过程中所需投入的直接和间接的一种有效能之量称为其具有的能值；单位能量相当的能值称为该能量的能值转换率，能值和能值转移率揭示了能量的能质、等级及其真实价值；以能值尺度可衡量比较不同类别的能量，综合分析各种生态系统的生态流，定量研究生态与经济效率及其关联。

| Abstract: | The concept of emergy and its use for comparing with energy were discussed in this paper.Emergy was defined as the amount of available energy required directly and indirectly to make a product or services,and emergy analysis was based on the solar emergy units (solar emjoules).Emergy provided the methodology with a common basis for measuring the value of different kinds of energy,and for evaluating the contributions from nature and humanity.A comparison of emergy analysis with previous energy analysis was also performed. |
