缙云山慈竹种群生物量结构研究

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

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200 ha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%。

The biomass structures of Neosinocalamus affins population and theirinfluentive factors were studied at two levels (the population in commu-nity level and the population in individual level) using Harper′s the theoryof moduler structure in Jinyun Mountain, the paper sums up the follow-ing was concluded from the result in Neosinocalamus affinis clone popula-tion 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 populationis 156.407t·ha^(-1); in the modular structure population of Neosinocalas af-finis the biomass distribution per module unit of construction was 49.46%of Glum, 21.34% of branch, 8.73% of leaf, 14.00% of rhizome, and6 .47% of root. In the zygote population of Neosinocalamus affinis in 200ha, the total biomass was 31281 ton. And the proportions of above groundand the underground biomass are 79.53% and 20.47%.
