| 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. |
