Data for GLS and SEM models-Satdichanh et al. 2018

Data used for linear models and Structural Equation Modeling (SEM). AGB: Aboveground biomass. PSR: Phylogenetic species richness. Species diversity (Fisher's alpha). Elevation: elevation of each plot. Slope: Slope of each plot. PCA1, PCA2 and PCA3: Soil PCA axes. Succession: SFI: secondary forest < 15 years old; SFII: secondary forest 15-30 years old; SFIII: secondary forest 30-100 years old; OGF: old growth forest >100 years old本数据集适用于线性模型与结构方程模型（Structural Equation Modeling, SEM）的分析。相关变量说明如下：AGB为地上生物量（Aboveground biomass）；PSR为系统发育物种丰富度（Phylogenetic species richness）；物种多样性指标采用费希尔α指数（Fisher's alpha）；Elevation为各样地的海拔高度；Slope为各样地的坡度；PCA1、PCA2与PCA3为土壤主成分分析轴；Succession为森林演替阶段，具体分类如下：SFI指林龄小于15年的次生林；SFII指林龄15至30年的次生林；SFIII指林龄30至100年的次生林；OGF指林龄大于100年的原始成熟林。
