图5. 不同退化阶段高寒草甸的生物多样性。图中不同字母表示处理之间有显著差异(p < 0.1)。实线是非线性拟合结果, 虚线是线性拟合结果。Control, 对照, 无退化草甸; D1, 轻度退化草甸; D2, 中度退化草甸; D3, 重度退化草甸; D4, 极度退化草甸。
Fig. 5. The species diversity of alpine meadow in different degradation stages. Different letters in figures indicate significant difference (p < 0.1). The solid lines are nonlinear fitting results. Dotted lines are linear fitting results. Control, non-degraded meadow; D1, mild degraded meadow; D2, moderate degraded meadow; D3, severe degraded meadow; D4, serious sandy meadow.
