图4. 退化梯度上土壤有机碳潜在输入量、输出量、积累量变化特征(平均值±标准误)。AM, 高寒草甸; HD, 重度退化高寒草甸; SD, 轻度退化高寒草甸。不同小写字母表示该指标在退化梯度上差异显著(p < 0.05)。
Fig. 4. Characteristics of potential input, output, and accumulation of soil organic carbon along degradation gradients (mean ± SE). AM, alpine meadow; HD, heavily degraded alpine meadow; SD, slightly degraded alpine meadow. Different lowercase letters indicate significant difference among the degradation stages (p < 0.05).
