图2. 内蒙古典型草原不同程度灌丛化样地草本物种丰富度(A)和功能性状多样性(B)的变化(平均值+标准误差)。功能性状多样性(FAD)由4个性状(株高、株丛生物量、茎叶比和比叶面积)计算而得。不同小写字母表示各样地间差异显著(p < 0.05)。
Fig. 2. Species richness and functional attribute diversity (FAD) at light, moderate and heavy encroachment sites in Nei Mongol typical steppe (mean + SE). FAD was calculated by plant height, plant biomass, stem:leaf biomass ratio and specific leaf area. Different lowercase letters indicate significant differences among sites (p < 0.05).
