Initial litter quality of the investigated litter types (mean ± SE, n = 3).

TC: total carbon; TN: total nitrogen; TP: total phosphorus.Different lowercase letters indicate significant differences among different litter types (p Initial litter quality of the investigated litter types (mean ± SE, n = 3).TC：总碳（total carbon）；TN：总氮（total nitrogen）；TP：总磷（total phosphorus）。不同小写字母表示不同枯落物类型间存在显著差异（p < 0.05）。供试枯落物类型的初始枯落物品质指标（平均值±标准误，n=3）
