图2. 最终多元模型中保留的各变量对于凋落物产量(A)和凋落物产量稳定性(B)的相对重要性的层次划分分析。CWMLC, 叶片碳含量; CWMLN, 叶片氮含量; CWMSLA, 比叶面积; DBHmax, 最大胸径; Hmax, 最大树高; PD, 系统发育多样性; Rao’s Q, Rao二次熵; Richness, 物种丰富度; TBA, 胸高断面积。
Fig. 2. Relative importance of variables retained in the models explaining litterfall production (A) and temporal stability of litterfall (B), as obtained by the hierarchical partitioning analyses. CWMLC and CWMLN, community weighted mean of leaf carbon and nitrogen content, respectively; CWMSLA, community weighted mean of specific leaf area; DBHmax, maximum diameter at breast height; Hmax, maximum tree height; PD, phylogenetic diversity; Rao’s Q, Rao’s quadratic entropy; TBA, total basal area.
