摘　　要：对四季竹(Oligostachyum lubricum)纯林和混交林2年生立竹构件生物量分配格局及枝、叶空间分布特征进行了研究。结果表明:纯林经营显著提高了竹子的全高和节间长度,增加了杆的生物量和分配比例,并使冠层上移以及叶片在冠层的分布上移,而对枝下节数和总节数没有显著影响。Determination was conducted on biomass allocation and spatial distribution of branch and leaf of 2-year Oligostachyum lubricum under management of pure and mixed stands. The result demonstrated that pure bamboo management could increase culm height and internode length, as well as increase allocation and percentage of biomass in the culm, making crown and leaf upward. While it had no evident effect on node number of the whole culm and that under branch.
