| 摘要: |
| 结果表明:26龄杉木纯林群落生物量平均为183.89t/hm2,其组成层次的生物量分配序列(%)为乔木层(93.60) > 枯枝落叶层(6.14) > 灌草层(0.26)。乔木层年平均净生产量为6.62t/hm2·a,低于中心产区;平均木单株年平均净生产量10.93kg/a,高于中心产区,揭示现有林分密度偏小。26年生林分平均树高和平均胸径分别为20.7m和24.0cm,其干材生物量平均达61.5%,适宜培育杉木大径材。 |

| Abstract: |
| Community biomass in 26 years pure stand of Cunninghamia lanceolata was 183.89 t/hm2 and distribution array of its biomass was tree layer(93.60%) > litter layer(6.14%) > shrub-herb layer (0.26%). An average net production of society in the tree layer was 6.62 t/hm2. a and lower than central origin, But the production of individual in the tree layer was 10.93 kg/a, and higher than.central origin. Indicated density of stand was small. Mean height and diameter of 26 years stand were 20.7 m and 24.0cm, respectively, and a percentage of its trunk was 61.5%. Where may be used as a great-diameter-timber forest base. |
