摘　　要：对江淮丘陵地区麻栎(Quercus acutissima Carr.)人工林地上部各组分干质量热值、去灰分热值、灰分含量、能量现存量的积累、结构和分配特征进行了研究。结果表明:各组分的干质量热值、去灰分热值和灰分含量存在显著差异,干质量热值由大到小依次为:叶片、树皮、树干、枝条,去灰分热值由大到小为:叶片、树皮、树干、枝条,灰分含量由大到小为:叶片、树皮、枝条、树干;萌芽更新林分能量现存量高于植苗更新林分,林分能量现存量随林龄和密度的增大而不断增加,到一定林龄后,又随林分的密度增加而减小;各组分能量现存量的比例顺序保持不变,由大到小为:树干、枝条、叶片,树干的比例随树龄的增大不断增加,枝叶的比例表现为前期叶片比例大于枝条,后期则相反。Gross caloric value, ash free caloric value, ash content and the distribution of energy accumulation of aboveground 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.
