图4. 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)的种间变异系数(ZCV)。黑、灰、浅灰色直线分别为草本、落叶灌木和常绿灌木植物ZCV的平均值, 地点名称后的数字分别为该地点草本、落叶灌木和常绿灌木植物种数。

Fig. 4. Inter-species coefficient of variation (ZCV) 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 mean ZCV values for graminoids, decidous shrubs and evergreen shrubs, respectively. The numbers after site names indicate the number of species for graminoids, decidous and evergreen shrubs, respectively.
