图3. 青藏高原高寒草地5个采样点不同退化程度上土壤微生物碳(MBC)、氮(MBN)、磷(MBP)含量及其化学计量比的变化(平均值±标准差)。不同小写字母表示各项指标在不同退化程度之间的差异性(p < 0.05); NS, p > 0.05。
Fig. 3. Changes in soil microbial biomass carbon (MBC), nitrogen (MBN) and phosphorus (MBP) and their stoichiometric ratios along the degradation sequence for the five sampling sites in Qingzang Plateau alpine grassland (mean ± SD). HD, heavy degradation; MD, moderate degradation; ND, non-degradation. Different lowercase letters indicate significant differences among different grasslands degradation levels (p < 0.05); NS, p > 0.05.
