Abstract:The biomass and calorie value as well as the decomposition ra‘e of witherer and even the biomass and respiration rate of edaphon on the Leymus Chinensis Grassland in Northeast China, were examined. The results were, furthermore calculated for energy contents. In the energy flow of edaphon , the energy content of Leymus Chintnsis is 206.57 kcal/m2.Yr and the energy content original from Leymus Chinensis decomposed by edaphon is 83.99 kcal/m2.Yr. The consumed energy for respiration of edaphon is 20.64 kcal/m2...
