图1. 青藏高原人工草地地上生物量动态变化特征(平均值±标准误)。1, 无芒雀麦; 2, 老芒麦; 3, 垂穗披碱草; 4, 西北羊茅; 5, 中华羊茅; 6, 青海扁茎早熟禾; 7, 星星草; 8, 冷地早熟禾。不同小写字母表示同一龄期不同物种地上生物量差异显著(p < 0.05)。
Fig. 1. Dynamics of aboveground biomass in artificial pastures on Qingzang Plateau (mean ± SE). 1, Bromus inermis; 2, Elymus sibiricus; 3, E. nutans; 4, Festuca ryloviana; 5, F. sinensis; 6, Poa pratensis var. anceps ‘Qinghai’; 7, Puccinellia tenuiflora; 8, Poa crymophila. Different lowercase letters represent significant differences in aboveground biomass among different species of the same age (p < 0.05).
