图4. 内蒙古典型草原单子叶和双子叶植物叶片碳(C)、氮(N)、磷(P)含量(A、B、C)及计量比值(D、E、F)的季节动态(平均值±标准偏差)。回归图中的实线表示特定功能类群的特定计量指标随生长季的推移有显著变化(p < 0.05), 虚线表示特定功能类群的特定计量指标随生长季的推移有边缘显著变化趋势(0.05 < p < 0.1)。
Fig. 4. Seasonal dynamics of leaf carbon (C), nitrogen (N) and phosphorus (P) concentrations (A, B, C) and their ratios (D, E, F) in monocotyledons and dicotyledons in a typical steppe in Nei Mongol (mean ± SD). The solid line in the regression diagram indicates that the specific index of certain group has a significant change trend with growing season (p < 0.05). The dashed line indicates that the specific index of certain group has a marginal significant change trend with growing season (0.05 < p < 0.1).
