Summary of model comparisons for each ecosystem process as well as multifunctionality.

The weight of support for the alternative models (TD: taxonomic diversity, FI: functional identity, FD: functional diversity) and estimates of model parameters for each ecosystem process (Cottondecomp: cotton decomposition, Litterdecom 98: litter decomposition in 1998, Productivity: productivity as annual biomass production, Npool bm: nitrogen pool size in aboveground biomass, Multifunctionality: mean performance over all processes). Results of likelihood ratio tests comparing nested models (L.Ratio) and associated p-values. Adjusted R2s for the ordinary least squares regression models and p-value associated to the multiple regressions are presented. The lowest AICc value for each process, the highest adjusted R2 and the significant differences between models (p备选模型的支持权重（其中TD即分类多样性（taxonomic diversity, TD）、FI即功能属性（functional identity, FI）、FD即功能多样性（functional diversity, FD）），以及各生态系统过程对应的模型参数估计值。涉及的生态系统过程包括：棉花分解（Cottondecomp）、1998年枯落物分解（Litterdecom 98）、以年生物量生产量计的生产力（Productivity）、地上生物量氮库规模（Npool bm）以及涵盖所有过程平均表现的多功能性（Multifunctionality）。本数据集包含比较嵌套模型的似然比检验结果（似然比L.Ratio与对应p值），普通最小二乘回归模型的调整后R²，以及多元回归对应的p值。同时呈现了各过程的最低AICc值、最高调整后R²以及模型间的显著差异（p
