以中国南方马尾松为研究对象,对南方马尾松不同器官的碳素含量、灰分含量与去灰分热值的分布特征进行研究。结果表明：①南方马尾松林分的平均碳素含量、灰分含量与去灰分热值分别为50.55%,1.02%,21.74 kJ.g-1;枝、叶、干、皮、根相互之间的平均碳素含量、灰分含量、去灰分热值都具有显著性差异;②认为将树干（去皮）中部位（3.5/10树高处）碳素含量,皮的上、中、下部位的平均去灰分热值,枝的中、下部位的平均灰分含量可分别作为整株碳素含量、去灰分热值、灰分含量是可行的;③马尾松碳素含量、去灰分热值、灰分含量三者之间均存在较强的相关性,其中去灰分热值与灰分含量的相关性系数达0.668;④马尾松碳素含量比较稳定,与林木起源、胸径、年龄等因子相关不显著,而去灰分热值、灰分含量与胸径、年龄、冠幅、树高相关性显著,与起源、坡度、海拔等因子相关性不明显。
以中國南方馬尾鬆為研究對象,對南方馬尾鬆不同器官的碳素含量、灰分含量與去灰分熱值的分佈特徵進行研究。結果錶明：①南方馬尾鬆林分的平均碳素含量、灰分含量與去灰分熱值分彆為50.55%,1.02%,21.74 kJ.g-1;枝、葉、榦、皮、根相互之間的平均碳素含量、灰分含量、去灰分熱值都具有顯著性差異;②認為將樹榦（去皮）中部位（3.5/10樹高處）碳素含量,皮的上、中、下部位的平均去灰分熱值,枝的中、下部位的平均灰分含量可分彆作為整株碳素含量、去灰分熱值、灰分含量是可行的;③馬尾鬆碳素含量、去灰分熱值、灰分含量三者之間均存在較彊的相關性,其中去灰分熱值與灰分含量的相關性繫數達0.668;④馬尾鬆碳素含量比較穩定,與林木起源、胸徑、年齡等因子相關不顯著,而去灰分熱值、灰分含量與胸徑、年齡、冠幅、樹高相關性顯著,與起源、坡度、海拔等因子相關性不明顯。

In this paper,based on the data of Masson pine（Pinus massoniana）in southern china,the carbon content,ash contents and ash free caloric values of different organs were analyzed.The results showed as follows： ①the average carbon content,ash contents and ash free caloric values of Masson pine is 50.55%,1.02%,21.74kJ·g-1,the average carbon content,ash contents and ash free caloric values of different organs are significantly different;②this paper presented that the carbon content,ash free caloric values and ash contents of Masson pine could be gained respectively by investigating the carbon content of stem at relative tree height 3.5/10,the average ash free caloric values of stem bark at relative tree height 1.0/10,3.5/10 and 7/10,the average ash contents of branch at middle and lower storey;③there is a significantly related among the carbon content,ash free caloric values and ash contents,the correlation coefficient between ash contents and ash free caloric values is 0.668;④the carbon content of Masson pine is relatively stable,and is not related significantly with the tree origin,diameter and age and etc.But ash free caloric values and ash contents are related significantly with the diameter,age,crown and height,and are not related significantly with the tree origin,slope,elevation and etc.
