图5 不同退化阶段亚高山草甸土壤原生生物群落非度量多维尺度分析(NMDS) (a)及相异性分析(基于Bray-Curtis距离) (b)。r = 0.577, P < 0.001为不同退化阶段亚高山草甸之间原生生物群落相似性的ANOSIM检验结果。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。

Fig. 5 Non-metric multidimensional scaling (NMDS) (a) and dissimilarity analysis (based on Bray-Curtis distance) (b) of soil protist communities in subalpine meadow at different degradation stages. The r = 0.577, P < 0.001 are the ANOSIM test results of protist community similarity between subalpine meadows in different degradation stages. ND, Nondegraded meadow; LD, Lightly degraded meadow; MD, Moderately degraded meadow; HD, Heavily degraded meadow.
