图2 内蒙古温带草地所有植物比叶面积(SLA)和叶片的N含量(A, E)、P含量(B, F)、N:P (C, G)、组织密度(D, H)在两个水平上的相关关系(II类线性回归)。A-D, 种群水平; E-H, 物种水平, 用物种平均值。

Fig. 2 Relationships between specific leaf area (SLA) and leaf N concentrations (A, E), P concentrations (B, F), N: P ratios (C, G), tissue density (D, H) at two levels across all species in Inner Mongolia grassland (type II linear regression). A-D, population level; E-H, interspecific level, using species means.
