图2. 不同草地类型地上活体生物量、凋落物生物量与根系生物量(平均值±标准偏差)。1, 温性草原; 2, 温性草甸; 3, 温性山地草甸; 4, 低地盐化草甸; 5, 暖性草丛; 6, 暖性灌草丛。不同的小写字母表示不同草地类型间的生物量差异显著(p < 0.05)。
Fig. 2. The aboveground biomass, litter mass and root biomass in different types of grasslands (mean ± SD). 1, temperate steppe; 2, temperate meadow; 3, temperate mountain meadow; 4, low-land saline meadow; 5, warm-temperate tussock; 6, warm- temperate shrub tussock. Different lower-case letters indicate significant differences in biomass among different types of grasslands (p < 0.05).
