Based on the investigation and research of vertical distribution characteristics of 11 years Castanopsis fissa plantations’ biomass, the results showed that during the biomass of different organs of standard wood, tree trunks was the biggest, leaves was the lowest, the order of each organ’s biomass was as follow: trunk (47.56%) > branch (25.71%) > root (15.79%)>leaf (10.94%). In stand biomass of different levels, the tree layer was the largest up to 363.89 t/hm 2, followed by litter layer, 36.12 t/hm2, low was shrubs herb layer at 29.67 t/hm2;order of biomass allocation rate at each layer was as follow:tree layer (84.66%)>litter layer (8.41%)>shrub herb layer (6.91%).%通过对11年生闽粤栲人工林生物量垂直分布特征的调查研究，结果表明：标准木各器官的生物量以树干最大，树叶最低，各器官生物量高低顺序依次为干部（47.56%）＞枝部（25.71%）＞根部（15.79%）＞叶部（10.94%）。林分不同层次的生物量以乔木层最大，达363.89 t/hm2，其次为凋落物层，达36.12 t/hm2，灌木草本层较低，为29.67 t/hm2；各层生物量分配率高低顺序依次为乔木层（84.66%）＞凋落物层（8.41%）＞灌木草本层（6.91%）。
