图4. 不同草地类型地上活体碳密度、凋落物碳密度与根系碳密度(平均值±标准差)。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的生物量之间差异显著(p < 0.05)。
Fig. 4. The aboveground carbon density, litter carbon density and root carbon density 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 carbon density among different types of grasslands (p < 0.05).
