图3. 大兴安岭泥炭地植物叶片C、N、P含量(A、B、C)及其计量值(D、E、F)的地点间变异系数(KCV)。黑、灰、浅灰色直线分别为草本、落叶灌木和常绿灌木植物KCV的平均值, 植物名称缩写下面的数字为出现的地点数。Bf, 柴桦; Cc, 地桂; Cg, 玉簪薹草; Da, 小叶章; Ev, 白毛羊胡子草; Lp, 杜香; Rc, 头花杜鹃; Sm, 越桔柳; Sr, 细叶沼柳; Vu, 笃斯越桔; Vv, 越桔。

Fig. 3. Inter-site coefficient of variation (KCV) in leaf C, N, and P concentrations (A, B, C) and their stoichiometric ratios (D, E, F) in peatland plants of Da Hinggan Ling. Lines in black, grey, and light grey mark the mean KCV values of graminoids, deciduous shrubs and evergreen shrubs, respectively. The number below each species indicates the number of occurring locations. Bf, Betula fruticosa; Cc, Chamaedaphne calyculata; Cg, Carex globularis; Da, Deyeuxia angustifolia; Ev, Eriophorum vaginatum; Lp, Ledum palustre; Rc, Rhododendron capitatum; Sm, Salix myrtilloides; Sr, Salix rosmarinifolia; Vu, Vaccinium uliginosum; Vv, Vaccinium vitis-idaea.
