图2 不同雪被处理对川西亚高山森林土壤可提取腐殖质含量(A)、胡敏酸含量(B)、富里酸含量(C)、胡敏酸/富里酸(D)、胡敏酸/可提取腐殖质(E)、色调系数(F)、光密度值(G)和A600/C (H)的影响(平均值±标准差, n = 5)。*表示在同一土层中不同时间主效应之间的差异显著(p < 0.05)。不同大写字母表示同一土层不同处理间主效应差异显著(p < 0.05)。不同小写字母表示同一土层相同时间下不同处理间简单效应差异显著(p < 0.05)。

Fig. 2 Effects of different snow treatments on soil extractable humus content (A), humic acid content (B), fulvic acid content (C), humic acid/fulvic acid (D), humic acid/extractable humus (E), hue coefficient (F), optical density value (G), and A600/C (H) in subalpine forest soils in western Sichuan (mean ± SD, n = 5). * indicating significant differences in main effects at different times in the same soil layer (p < 0.05). Different uppercase letters indicate significant differences in main effects between treatments at the same soil layer (p < 0.05). Different lowercase letters indicate significant differences in simple effects between treatments at the same time and soil layer (p < 0.05).
