| 摘 要： | 根据退耕还林尾叶桉模式3个样地的调查资料,对乔木层采用平均木法,对灌木层、草本层、枯落物层采用收获法获取生物量,同时对样地内的枯落物进行持水量计算。结果表明:退耕还林尾叶桉模式的乔木层、灌木层、草本层、枯落物层的生物量分别为59 654.7、1 027.38、02.7和3 393.0 kg/hm2,其中乔木层中尾叶桉各器官生物量大小的排列顺序为:干材>树根>树皮>枝>叶。随着林龄的增加,尾叶桉枯落物的持水能力逐年增加。

| Abstract: | Based on the investigation data of three samples of Eucalyptus urophylla in the conversion of cropland to forest,the tree layer biomass was estimated by the way of average tree,and the shrub,herb and litter layer were adopted by harvesting method to calculate biomass.Meanwhile,the water-holding capacity of litter in sample was also calculated.The result showed that: the tree layer biomass was 59 654.7kg/hm2;the shrub layer biomass was 1 027.3 kg/hm2;the herb layer biomass was 802.7 kg/hm2 and the litter layer biomass was 3 393.0 kg/hm2,respectively.The biomass and its distribution of Eucalyptus urophylla were in the order of stem> root > bark > branch > leaf.With the forest age increasing,the water-holding capacity of Eucalyptus urophylla litter was increased. |
