The biomass and energy partitioning in the warm temperate deciduous broad-leaved forest were analyzed. The partition of biomass and energy in oak forest ecosystems showed that the dominant tree species oak accounts for the biggest percentage in the forest. The biomass of oak forest was 60–200 t·hm–2, tree layer 50–160 t·hm–2. The percentage of tree layer biomass in community was 80%–90%, the percentage of oak biomass is 40%–100%. The forest net primary production was 5–24 t·hm–2. The standing total energy value of the oak community was 83000 kcal·m–2. The tree layer accounted for 96.65%, shrub layer 3.12%, and herb layer 0.23%. The energy density orders at different organs of tree layer were stem, root, branch and leaf, and the ratio was in 4:3:2:1. Shrub layer orders were stem, branch, root and leaf. After the biomass and energy density were analyzed, the concept model was developed for biomass and energy. The concept model would be the basis for abstracted mathematical and computer models will be established.
