摘　　要：通过对云南省思茅松集中分布区不同林龄的思茅松人工林含碳率的测定与分析,结果表明：思茅松人工林林木主干与其它构件的平均含碳率存在显著差异,主干的含碳率最高（48.48%）,由基部向梢头含碳率呈下降趋势,其它构件的含碳率依次为树枝（48.13%）、主干皮（47.49%）、松针（47.27%）、球果（47.02%）和树根（46.80%）。在所测定的4个径级组中,径级组1（16-30 cm）林木主干的平均含碳率（48.43%）显著高于其它小径级组,小径级组间的含碳率差异不明显;树枝、主干皮、松针、球果和树根的含碳率在不同径级组间的差异不明显。思茅松人工中幼林单株的全株含碳率为47.91%。The carbon content of the plantation of Pinus Kesiya Royle ex Gord. Var.langbianensis with different ages in the distribution areas in Yunnan were tested and analysed.The results showed that the mean carbon contents of different organs varied significantly.The carbon content of main stem was the highest as 48.48% and tended to decrease from the base to the shoot upward.Carbon contents followed were 48.13%,47.49%,47.27%,47.02% 46.80% in branch,bark from main stem,needle leaf,cone and root respectively.Of the four tested diameter classes,the carbon content of main stem from Class 1（16-30cm）was significantly higher than that of other classes,the differences of carbon contents of small diameter classes was not evident.The carbon contents in branch,bark of main stem,needle leaf,cone and root from different diameter classes were not significantly different.The whole tree carbon content of Pinus Kesiya Royle ex Gord Var.langbianensis young and middle aged plantations was calculated as 47.91%.
