图1. 模拟酸沉降对土壤微生物生物量碳(MBC)、氮(MBN)和磷(MBP)含量以及微生物化学计量比的影响(平均值±标准误)。CK, 对照, pH = 4.5; T1, pH = 4.0; T2, pH = 3.5; T3, pH = 3.0。不同小写字母表示相同土层不同处理下差异显著(p < 0.05); ns表示不存在显著差异(p > 0.05)。
Fig. 1. Effects of simulated acid rain treatments on soil microbial biomass carbon (MBC), nitrogen (MBN), phosphorus (MBP) content and microbial stoichiometric ratio (mean ± SE). CK, control, pH = 4.5; T1, pH = 4.0; T2, pH = 3.5; T3, pH = 3.0. Different lowercase letters indicate significant difference between treatments in the same soil layer (p < 0.05); ns indicates no significant difference (p > 0.05).
