图2 不同退化阶段亚高山草甸土壤原生生物优势门(a)和存在显著差异优势门(b)的相对丰度。ND: 未退化草甸; LD: 轻度退化草甸; MD: 中度退化草甸; HD: 重度退化草甸。P值表示不同退化阶段亚高山草甸间土壤原生生物门相对丰度的差异水平, *表示存在显著差异(P < 0.05)。

Fig. 2 Relative abundance of dominant (a) and significantly differentially dominant (b) phyla of soil protist in subalpine meadow at different degradation stages. ND, Nondegraded meadow; LD, Lightly degraded meadow; MD, Moderately degraded meadow; HD, Heavily degraded meadow. P value indicates the level of difference in relative abundance of soil protists among subalpine meadows at different stages of degradation, and * indicates a significant difference (P < 0.05).
