| 摘 要： | 基于对5个林龄尾巨桉林分不同层次植被生物量和碳含量的测定,本文研究了5个不同林龄尾巨桉林分植被碳储量的分配格局.结果表明:5个不同林龄尾巨桉林分中乔木层、林下灌木层、林下草本层和凋落物层碳含量均值分别为47.64%、50.59%、44.41%和48.92%,碳储量为7.17~145.15 t·hm-2,随林龄增加而增大.乔木层碳储量所占比例最大,随林龄增加乔木层碳储量所占比例也逐渐增大.

| Abstract: | Vegetation biomass and carbon contents in Eucalyptus urophylla × E. grandis plantations were examined by sampling plantations of five different ages. The results showed that the average carbon content of tree layer, shrub layer, herb layer and litter layers were 47.6%, 50.6%, 44.4% and 48.9% respectively in the five stands in this study. The carbon storage of the five plantation stands varied from 7.17 t·hm-2 to 145.15 t·hm-2, and generally increased as plantation age increased. The tree layer accounted for the largest proportion of total carbon stored in all five stands, and this proportion also increased with the plantation age. |
