图1. 不同退化程度草地芦苇植株高度和地上干质量的变化趋势(平均值±标准误差, n = 5)。不同小写字母表示不同处理间差异显著(p < 0.05)。NG, 正常草地; MDG,中度退化草地; SDG, 重度退化草地。
Fig. 1. Changes of plant height and shoot dry mass of Phragmites communis in different degrees of degraded grasslands (mean ± SE, n = 5). Different lowercase letters indicate significant differences among the different degrees of degraded grasslands (p < 0.05). NG , normal grassland; MDG , moderate degraded grassland; SDG , severe degraded grassland.
