Abstract:
Gross caloric value, ash free caloric value, ash content and the distribution of energy accumulation of aboveground of Quercus acutissima plantations were studied in Jianghuai region. The results showed that there was significant difference in gross caloric value, ash free caloric value and ash content of different components, the gross caloric value in the components was as follow: leaf, bark, stem, branch,ash free caloric value was leaf, bark, stem, branch and ash content was leaf, bark, branch, stem. Energy accumulation of regeneration by sprout better than afforestation by planting, with the increase of the density and stand age, the amount of energy accumulation increased, but after a specific stand age, it decreased along with increment in stand density. The distribution pattern of different components was stem, branch, leaf, the proportion of stem was increased with increment in stand age, on the contrary to anaphase, the proportion of leaf is bigger than that of branch in prophase.
