- 摘要:
- 采用年轮分析法对岩溶区青冈栎样树年轮和生物量进行测定并对其群落生物量进行估算。研究结果显示,青冈栎平均树龄46 a,平均胸径20.52 cm,单位地上生物量为98.668 t·hm2。随着植株的生长,胸径越大则生物量越大,两者形成明显的幂函数关系。d、e、f、g和h样树地上生物量为2.884、22.567、108.183、134.314和379.799 kg,生物量分配状况是主干>枝条>树叶,大部分的生物量分配在主干,生物量随着胸径的增大明显加大。
- Abstract:
- Treering character and biomass of Cyclobalanopsis glauca were measured by method of treering analysis and its aboveground biomass was analysed in karst region. The results showed that average age, average diameter and aboveground biomass of C.glauca in karst forest was 46 a, 20.52 cm and 98.668 t·hm2, respectively. With increase of the diameter,the biomass was markedly increased. The aboveground biomass of sample tree d, e, f, g and h was 2.884, 22.567, 108.183, 134.314 and 379.799 kg, respectively. Most of the biomass was distributed in the trunk, and the distribution order was trunk>branches>leaves.
