图2. 川西亚高山3种林型凋落物自然输入与去除土壤的胡敏酸/富里酸(平均值±标准误)。不同小写字母表示同一林型相同处理下不同采样时间土壤胡敏酸/富里酸差异显著(p < 0.05)。*, 同一采样时间凋落物自然输入与凋落物去除之间差异显著(p < 0.05)。
Fig. 2. Humic acid/fulvic acid ratio as affected by litter input in broad-leaved forest, mixed coniferous and broad-leaved forest and coniferous forest in subalpine forests of western Sichuan (mean ± SE). Different lowercase letters indicate that the differences in humic acid/fulvic acid ratio between measurement times under given litter treatments are significant (p < 0.05). *, significant differences in humic acid/fulvic acid ratio between litter treatments in the same measurement time (p < 0.05).
