摘 要:以16 a到70 a的11株栓皮栎为研究对象,分别测定其树叶、树皮、树枝、树干的干重热值、灰分含量及碳含量值;利用栓皮栎各器官的干重比值计算栓皮栎地上部分的干重热值、灰分含量和碳含量值,运用SPSS软件对栓皮栎地上部分热值与碳含量做曲线估计,得出最佳拟合方程。结果表明:栓皮栎树叶和树皮的热值含量较高,是地上植株部分的主要热值器官,树叶、树皮的热值与碳含量的相关性强于树枝、树干热值与碳含量的相关性;栓皮栎地上部分的干重热值与碳含量、去灰分热值与碳含量的最佳模型均为二次方模型,分别为:y=-190.911x^2+1182.426x-28.057、y=-131.696x^2+137.217x-18.841,相关系数分别为0.929、0.933。研究结果可为栓皮栎能源林灌木化的可行性提供参考。11 trees of Quercus variabilis from age 16 to age 70 are chosen as the research objects,and then the gross caloric values,ash content and carbon content value of leave,bark,branch and trunk were determined in turn.To use the dry weight ratio to calculate the gross caloric values,ash content and carbon content of the aerial part.Making curve estimations of the aerial part caloric values and carbon content to get the the best fitting equation by using SPSS.The results show that:the caloric value of leave and bark is much higher,which means the main energy supply organs are leave and bark,the correlation of caloric value and carbon content of leave and bark is stronger than the branch and trunk; the best-fit model of the gross caloric value and carbon content is quadratic linear regression model,the ash-free caloric value either,y =-190.911x^2+ 1182.426x-28.057,y =-131.696x^2+ 137.217x-18.841,the correlation index are 0.929 and 0.933.The results can be providing a reference for the feasibility of Quercus variabilis energy forest.
