图1. 典型阔叶红松(Pinus koraiensis)林不同树种冠层内的叶性状值(平均值+标准误差)。小写字母代表同一树种不同冠层之间叶性状的差异显著性(α = 0.05)。
C, 叶碳含量; CCI, 叶绿素含量指数; LDMC, 叶干物质含量; LMA, 比叶质量; LT, 叶片厚度; N_area, 单位面积的叶氮含量; N_mass, 单位质量的叶氮含量; P_area, 单位面积的叶磷含量; P_mass, 单位质量的叶磷含量。横坐标物种名称缩写见表1。

Fig. 1. Difference of leaf traits (mean + SE) across the canopy layers for different tree species in a typical mixed broadleaved- Korean pine forest. The lowercase letters indicate whether the trait differences were significant across the canopy layers (α = 0.05).
C, leaf carbon content; CCI, chlorophyll content index; LDMC, leaf dry mass content; LMA, leaf mass per area; LT, leaf thickness; N_area, leaf nitrogen content per leaf area; N_mass, leaf nitrogen content per leaf mass; P_area, leaf phosphorus content per leaf area; P_mass, leaf phosphorus content per leaf mass. The full names and abbreviations of species on the horizontal axis are shown in Table 1.
