图2 固沙植物水分利用效率(WUE)在不同时间(A)和空间(B)上的变化特征(平均值±标准误)。不同大写字母表示不同物种间WUE差异显著(p < 0.05), 不同小写字母表示同种固沙植物WUE在不同月份或不同地点间差异显著(p < 0.05)。

Fig. 2 Characteristics of temporal (A) and spatial (B) changes in water use efficiency (WUE) of different types of sand-fixing plants (mean ± SE). Different uppercase letters represent significant differences in WUE between different species (p < 0.05), and different lowercase letters represent significant differences in WUE of the same sand-fixing plant in different months or different spaces (p < 0.05).
