| 摘 要： | 对32年生擎天树人工林生态系统的碳素含量、碳贮量及其空间分配特征进行了研究。结果表明,擎天树不同器官碳素平均含量的变化范围为465.1～493.5 g/kg,各器官碳素含量依次为：细根〉树干〉树叶〉根兜〉中根〉粗根〉树枝〉干皮;32年生擎天树人工林生态系统的碳贮量为300.70 t/hm2,其中植被层碳储量为169.71 t/hm2,乔木层地上部分碳储量占整个植被层的84.22%。经估算,擎天树人工林乔木层净固碳量和碳素净积累量分别为11.30和5.20 t/（hm2.a）。

| Abstract: | The content,storage and spatial distribution of carbon in the ecological system of man-made forest of 32-years old Parashorea chinensis were studied.The results showed that the average carbon contents in different organs of Parashorea chinensis varied in the range of 465.1-493.5 g/kg;the carbon contents in its organs were as follows: thin root > tree trunk > leaves > root pocket > middle root > thick root > branches > trunk bark;the carbon storage of the ecological system of man-made forest of 32-years old ... |
