摘要
对近年来农业生态系统能流和能量分析研究的某些新进展进行了介绍和评述，重点介绍了ＨＴＯｄｕｍ所创立的能值概念和Ｇｉａｍｐｉｅｔｒｏ等人提出的生物物理资本概念。对这些新概念在农业生态系统分析中的应用进行了讨论。
some new progresses in the study of energy flowsand energetic analysis in agroecosystems,especially the concept ofemergy created by HTOdum and the concept of biophysical capi-tal created by Giampietro et al,are introduced and assessed. Some applications of these concepts in agroecosystem analysis arediscussed.
