缙云山慈竹种群生物量结构研究

 本文引用Harper的构件结构理论，从两个水平(即群落水平上的种群和个体水平上的种群)上研究了缙云山慈竹种群的生物量结构及其影响因素。 研究结果表明：(1)慈竹无性系种群中各个体生物量在1—5龄级的分配为：14.18%，24.22%，41.91%、12.30%和7.38%，种群现存生物量为156.407t·ha-1；(2)慈竹种群中，生物量在各构件单位的配置为：秆49.46%，枝21.34%，叶8.73%，根茎14.00%，根6.47%；(3)慈竹(合子)种群在200ha中的生物量为31281t。地上地下部分生物量各占种群总量的79.53%和20.47%。

STUDIES ON THE BIOMASS STRUCTURE OF NEOSINOCALAMUS AFFINIF POPULATION IN JINYUN MOUNTAIN

The biomass structures of Neosinocalamus affinis population and their influentive factors were studied at two levels (the population in community level and the population in individual level) using Harper′s the theory of moduler structure in Jinyun Mountain, the paper sums up the following was concluded from the result in Neosinocalamus affinis clone population the biomass distribution in the 5 age classes are 14.18%, 24.22%, 41.91%, 12.30% and 7.38%. And the current biomass of the population is 156.407t·ha-1; in the modular structure population of Neosinocalas affinis the biomass distribution per module unit of construction was 49.46% of clum, 21.34% of branch, 8.73% of leaf, 14.00% of rhizome, and 6.47% of root. In the zygote population of Neosinocalamus affinis in 200 ha, the total biomass was 31281 ton. And the proportions of above ground and the underground biomass are 79.53% and 20.47%.
