图1. 泥炭地每种植物残体及每处泥炭地所有植物残体的初始化学组成(平均值±标准误差, n = 5)。B_all, 桦木属; Ba, 红桦; Br, 油桦; Bf, 柴桦; C_all, 薹草属; Cd, 签草; Cl, 毛薹草; Cs, 瘤囊薹草; S_all, 泥炭藓属; Sp, 泥炭藓; Sc, 中央泥炭藓; Sf, 锈色泥炭藓。D, 来源地为大九湖的平均值; H, 来源地为哈泥的平均值; M, 来源地为满归的平均值。不同大写字母表示不同属之间初始化学组成差异显著(p < 0.05), 不同小写字母表示不同种和不同来源地之间初始化学组成差异显著(p < 0.05)。

Fig. 1. Initial chemical composition of each plant litter in a peatland and initial chemical composition of all the plant litters from each peatland (mean ± SE, n = 5). B_all, the mean of Betula; Ba, B. albosinensis; Br, B. fruticosa var. ruprechtiana; Bf, B. fruticosa; C_all, the mean of Carex; Cd, C. doniana; Cl, C. lasiocarpa; Cs, C. schmidtii; S_all, the mean of Sphagnum; Sp, S. palustre; Sc, S. centrale; Sm, S. magellanicum; Sf, S. fuscum. D, the mean of Dajiuhu; H, the mean of Hani; M, the mean of Mangui. Different capital letters indicate significant differences in initial chemical composition among genera (p < 0.05), and different lowercase letters indicate significant differences in initial chemical composition between both species in a genus or average of all the species among three sites (p < 0.05).
