| 摘 要： | 对处于更新期30 年橡胶人工林含碳量、生物量、碳贮量及其空间分布进行研究。结果表明:橡胶树组分的含碳量在29.94%～52.90 %之间,大小表现为:树叶>树干>树根>树枝>树皮>胶乳,相同器官的含碳量枯样的要比鲜样的高。凋落物层含碳量平均为51.90 %,林下植物为46.09 %。土壤含碳量平均为0.54%,随着土层深度的增加,各层次土壤含碳量逐渐减少,相邻土层差异不显著。橡胶林生态系统现存碳贮量为219.68 t·hm-2,其中乔木层为140.21 t·hm-2,占整个生态系统碳贮量的63.82 %,凋落物层和林下植被层为3.99 t·hm-2,仅占1.82 %,土壤(0～100 cm)的碳贮量为75.48 t·hm-2,占34.36 %。橡胶树各器官的碳贮量与其生物量成正比关系。树干的生物量最大,其碳贮量也最高,占乔木层碳贮量的55.67%。 |
| 关 键 词： | 橡胶林 碳贮量 含碳量 更新期 |

| Abstract: | The carbon content and its distribution in rubber(Hevea brasiliensis(Willd.ex A.Juss.) Muell.Arg.) plantation in regeneration period were studied.The results showed that the carbon content in different organs of rubber trees ranged from 29.94% to 52.90% and decreased with the order of leaves > trunk > root >branch> bark > latex.The carbon content of dry samples from the same organ was higher than that of fresh samples.The carbon content in litter layer and understory plant layer were 51.90% and 46.09 %,resp... |
