摘　　要：以长白山阔叶红松林中常见的6种槭属树种为调查对象,分别从树种、器官、径级等多角度对其干重热值进行对比分析.结果表明:6种槭属树种不同器官之间的干重热值差异显著性不同,枝和皮的干重热值与其他器官的干重热值差异极显著,而主根、干、叶和侧根之间的干重热值差异不显著,整体表现为:枝>主根>干>叶>侧根>皮;不同树种同一器官的干重热值存在一定差异,枝、干、侧根的干重热值最高的树种为花楷槭,皮和主根的干重热值最高的树种为青楷槭,叶的干重热值最高的树种为色木槭;同一树种不同器官的干重热值存在一定差异,6个树种中枝的干重热值是最高的,其次为干或主根;槭属树种的干重热值随着胸径的增大呈明显的波浪形分布.Six common Acer species in broad-leaved Korean pine forest in Changbai Mountain were taken as the investigation objects,and their dry weight calorific values were compared and analyzed from the perspectives of tree species,organs and diameter classes.The results show that there are significant differences in the dry weight calorific value among different organs of six Acer species.The dry weight calorific values of branches and barks are significantly different from that of other organs,but there are no significant differences among the dry weight calorific values of taproots,trunks,leaves and lateral roots.The overall performance is as follows:branches>taproots>trunks>leaves>lateral roots>barks.There are some differences in the dry weight calorific values of the same organ in different tree species.Dry weight calorific values of branches,trunks and lateral roots of Acer ukurunduense are the highest.Dry weight calorific values of barks and taproots of Acer tegmentosum are the highest.Dry weight calorific value of leaves of Acer mono is the highest.There are some differences in the dry weight calorific values of different organs of the same tree species.Among the six tree species,the dry weight calorific value of branches is the highest,followed by trunks or taproots.The dry weight calorific value of Acer species presents an obvious wavy distribution with the increase of diameter-class.
