对中国鼎湖山57种亚热带树种的相对生长率与7个功能性状的相关程度进行了评价，这些性状描述了与地形和肥力有关的生理行为和土壤环境因子。与RGR相关的各物种功能性状和土壤环境因子的平均值因个体发育阶段而异。幼树RGR与功能性状的关联度大于大树RGR，而大树RGR与土壤环境的关联度高于幼树RGR。相对生长率最强的单项预测因子是幼树的木材密度和大树的坡向。在RGR中，大树的逐步回归模型所占的变异比例(R2=0.95)大于幼树的逐步回归模型(R2=0.55)。功能多样性分析表明，随着群落从幼树向大树过渡，生境过滤过程可能有助于RGR调节的实质性变化。
We evaluated the degree to which relative growth rate (RGR) of saplings and large trees is related to seven functional traits that describe physiological behavior and soil environmental factors related to topography and fertility for 57 subtropical tree species in Dinghushan, China. The mean values of functional traits and soil environmental factors for each species that were related to RGR varied with ontogenetic stage. Sapling RGR showed greater relationships with functional traits than large-tree RGR, whereas large-tree RGR was more associated with soil environment than was sapling RGR. The strongest single predictors of RGR were wood density for saplings and slope aspect for large trees. The stepwise regression model for large trees accounted for a larger proportion of variability (R2= 0.95) in RGR than the model for saplings (R2= 0.55). Functional diversity analysis revealed that the process of habitat filtering likely contributes to the substantial changes in regulation of RGR as communities transition from saplings to large trees.
