摘　　要：对6个树龄栓皮栎不同器官的热值和碳含量进行了分析研究。结果表明:6个树龄栓皮栎叶、皮的干重热值均与树龄呈正相关,枝、干的干重热值均与树龄呈显著负相关;叶、皮的去灰分热值均与树龄呈极显著正相关,枝、干的去灰分热值均与树龄呈不显著正相关。不同器官的干重热值和去灰分热值总体上均表现为皮>叶>枝>干。不同器官的干重热值、去灰分热值之间均具有极显著差异(P<0.01)。皮的碳含量与树龄呈不显著正相关;叶的碳含量与树龄呈显著正相关;枝、干的碳含量与树龄呈不显著负相关。不同器官的碳含量总体上表现为皮>叶>干>枝。整体上热值与碳含量呈显著正相关。Caloric value and carbon content in different organs of Quercus variabilis of six ages were studied.The results showed that gross caloric values of both leave and bark were positive correlated with age.Gross caloric values of both branch and trunk were significant negative correlated with age.Ash free caloric values of both leave and bark were great significant positive correlated with age.Ash free caloric values of both branch and trunk were not significant positive correlated with age.Overall,both gross caloric value and ash free caloric value in different organs decreased in the order of bark,leave,branch and trunk.Differences of both gross caloric value and ash free caloric value were great significant among different organs（P0.01）.Carbon content of bark was not significant positive correlated with age.Carbon content of leave was significant positive correlated with age.Carbon content of both branch and trunk were not significant negative correlated with age.Overall,carbon content in different organs decreased in the order of bark,leave,trunk and branch.Caloric value was significant positive correlated with carbon content totally.
