图3. 内蒙古典型草原不同程度灌丛化样地草本群落加权性状值(CWM)的变化(平均值+标准误差)。群落加权性状值: PBCWM, 株丛生物量; PHCWM, 株高; SLACWM, 比叶面积; SLRCWM, 茎叶比。不同小写字母表示各样地间差异显著(p < 0.05)。
Fig. 3. Community-weighted mean traits (CWM) at light, moderate and heavy encroachment sites in Nei Mongol typical steppe (mean + SE). PBCWM, community-weighted plant biomass; PHCWM, community-weighted plant height; SLACWM, community-weighted specific leaf area; SLRCWM, community-weighted stem:leaf ratio. Different lowercase letters indicate significant differences among sites (p < 0.05).
