| 摘 要： | 文章对缙云山自然保护区淡竹叶种群的生物量生殖配置格局进行了研究．结果表明，淡竹叶种群的有性生殖配置比例较低；尽管淡竹叶种群的生物量配置格局随季节的变化而变化，但在针叶林和针阔混交林不同环境条件下其生殖配置比例并无显著差异，这与前人研究结果是一致的．表明淡竹叶种群生物量生殖配置是淡竹叶种群的基本特征之一，其配置格局反映了该物种对生存环境的适应性特征．

| Abstract: | The reproductive allocation (RA) of biomass in TBLophatherum gracile Brongn was investigated at Jinyun Mountain Reserve in this paper. The results show that the allocation in sexual reproduction of L. gracile Brongn population was relatively low; while the RA of biomass at L. gracile Brongn population changed with seasons, no obvious differences were found between the RA of L. gracile Brongn populations in the needle forest and theropencedrymion, which is similar to the previous reports. The results suggest that the RA of biomass is one of primary characteristics of the L. gracile Brongn population, and the RA reflects the adaptive character to its living environment. |
