| 摘 要： | 效率作为指示生产、生活中反映速率的指标被广泛应用.生态效率以生态能量学为基础,研究生态系统中的能量流动、传递与转化,计算营养级内部和营养级之间的能流的转化效率.传统的效率与生态效率的表达均具有主观性,并常把来源于不同类型、不同性质的能量进行简单或片面的比较.能值理论则把生态系统或生态经济系统中不同种类、不可比较的能量转化成同一标准的能值（太阳能）来衡量和分析,极大提高了生态效率研究的科学性与准确性.

| Abstract: | Efficiency is broadly applied,which is responded to the speed of production and life.Ecosystem efficiency with the Ecosystem energy for foundation,pursues the energy flowing、delivering and conversion of eco-system and compound eco-system,calculating every efficiency of energy flowing in the inner part or among the nourishments.The express the tradition efficiency and ecosystem efficiency is subjective,and ofen simply compare some energies which come from different type of them.Emergy theory can make those uncomparable energies become standard of Emergy（Solar emergy）.So Emergy theory greatly increase the science and accuracy of ecosystem efficiency research. |
