摘要
阐述了火用分析和能值分析的基本概念及其分析原理、发展和应用。通过分析比较火用分析和能值分析在解决生态系统问题上的异同 ,指出火用分析方法注重的是能量的做功能力 ,火用值的大小与环境介质紧密相联 ,火用值越高其做功能力就越大。能值分析方法是以能值为基准 ,并结合能值转换率 (通常是太阳能值转换率 )来分析比较生态系统中不同级别能量的价值和作用。
The concepts、analysis principles、development and applications of exergy analysis and emergy analysis were reviewed.The difference of these two methods when to solve the problems in ecosystem was compared.It was pointed out that exergy analysis put the emplasis on the ability of energy to do work,which the value of exergy was closely related to the medium of the environment and the higher the value was the stronger the ability would be.While the emergy analysis based on the emergy and its transformation ratio,generally the ratio of solar emergy,to compare the value and use of different energy in ecosystem.
