Abstract: Agro-ecolomic system was analyzed from the viewpoints of holographic relationship between ecosystem and organism,and the following common characters in eight aspects between agricultural production process and material metabolism were found:1.Substantial,2.Key node,3.Substitution or conversion,4.Targets,5.Two kinds of forms,6.Management or catalysis,7.Non-balanced process,8.Energy storage.The realistic significance of the analogical analysis was also discussed and some new concepts were put forward about the criteria system and calculating methods for assessing the ecolomic benefits

Key words: enhanced UV-B radiation, terrestrial ecosystem, carbon cycle, litter decomposition, soil respiration.
