中文摘要：生物多样性与生态系统功能之间的关系已成为森林生态系统研究的核心问题.然而,在具有不同人类干扰历史的亚热带森林群落中,关于环境因子对生物多样性与生态系统功能关系影响的研究仍然较少.在本研究中,选择位于中国东部浙江省的34个亚热带森林样地,在考虑样方中的环境因子的基础上,利用线性模型,分析样地中木本植物多样性(物种、功能和谱系多样性)与样方内木本植物生物量或生物量变化量之间的关系.物种多样性和功能多样性,并非谱系多样性,与生物量和生物量的变化量之间存在显着相关性.生物量或生物量变化量与年平均温度和海拔高度之间存在显著的正相关关系.此外,在考虑环境因子和森林群落的演替阶段时,生物量变化量与功能多样性的关系显著强于生物量变化量与谱系多样性或物种多样性之间的关系.这些研究结果表明,生物多样性与生态系统功能之间的关系可能取决于生物多样性指数的选择和环境条件.

外文标题：Decoupling the impact of biodiversity and environmental factors on the biomass and biomass growth of trees in subtropical forests

外文摘要：The relationship between biodiversity and ecosystem functioning has become a central issue in any forest ecosystem.However,there are few studies on the interaction of environmental factors based on the history of subtropical forest disturbance.In this study,we intended to disentangle the relationship between different aspects of biodiversity and biomass or biomass change when considering the environmental factors of 34 subtropical forest plots in Zhejiang Province,eastern China.We used linear models to analyze the effects of taxonomic,functional and phylogenetic diversity at the plot level of tree biomass and its growth with or without environmental factors.Taxonomic diversity and functional diversity,rather than phylogenetic diversity,showed significant correlations with biomass and biomass growth.We further found that there was a positive linear relationship between biomass or biomass growth and mean annual temperature and altitude.In addition,the relationship between biomass growth and functional diversity was significantly stronger than the relationship between biomass growth and phylogenetic diversity or taxonomic diversity when environmental factors and stand developmental stages were considered.Our results suggested that the relationship between biodiversity and ecosystem functioning is dependent upon the selection of diversity index and environmental conditions.
