图1. 排露沟流域0-10 cm (A-F)和10-20 cm (G-L)土壤有机碳(SOC)、全氮(TN)、全磷(TP)含量与计量比沿海拔梯度分布状况(平均值±标准误)。不同小写字母表示不同海拔高度的同一指标差异显著(p < 0.05)。
Fig. 1. Variations of soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP) contents and stoichiometry for the 0-10 cm (A-F) and 10-20 cm (G-L) soil layer across the altitude gradient (mean ± SE) in Pailugou watershed. Different lowercase letters indicate significant difference of the same indicator among different altitudes (p < 0.05).
