| 摘要: |
| [目的]为科学、可持续地经营桉树(Eucalyptus)人工林以及评价桉树人工林在区域碳循环中的地位、作用和生态效益提供有效的依据。[方法]采用平均标准木法和收获法对南宁七坡林场的尾巨桉(Eucalyptus urophylla×E.grandis)及其林下植被的生物量进行调查。[结果]在尾巨桉人工林中,各层次生物量呈现乔木层 > 灌木层 > 草本层,其中尾巨桉生物量最大,处于主导地位;尾巨桉各器官生物量的大小顺序为树干(64.38%) > 根(24.29%) > 树皮(5.97%) > 老枝(2.25%) > 嫩枝(1.56%) > 老叶(1.32%) > 嫩叶(0.20%)。[结论]尾巨桉的生物量主要集中在树干上,叶的生物量最少。 |

| Abstract: |
| [Objective] In order to provide effective reference for the management of Eucalyptus plantations sustainably and scientifically,and evaluate their roles,functions and ecological benefits in the regional carbon cycle.[Methods] Mean tree method and harvest method were used to study the biomass of Eucalyptus urophylla×E.grandis plantations and their understory vegetations in Nanning Qipo forest farm.[Results] In the plantations,the proportion of biomass in various layers was tree layer > shrub layer > herb layer,and the largest biomass was produced by Eucalyptus urophylla×E.grandis.This indicated that Eucalyptus urophylla×E.grandis tree is a dominant plant. The biomass of various organs of Eucalyptus urophylla×E.grandis were trunk(64.38%) > root(24.29%) > bark(5.97%) > old branch(2.25%) > tender branch(1.56%) > old leaf(1.32%) > tender leaf(0.20%).[Conclusion] The biomass of Eucalyptus urophylla×E.grandis was mainly produced by trunk and litte by the leaf. |
