图1. 不同植被恢复阶段的土壤有机碳含量(平均值±标准偏差)。LAG, 柯-红淡比-青冈常绿阔叶林; LCQ, 檵木-杉木-白栎灌木林; LVR, 檵木-南烛-杜鹃灌草丛; PLL, 马尾松-柯-檵木针阔混交林。不同大写字母表示同一土层不同植被恢复阶段之间差异显著(p < 0.05), 不同小写字母表示同一植被恢复阶段不同土层之间差异显著(p < 0.05)。

Fig. 1. Soil organic carbon concentration at different stages during vegetation restoration (mean ± SD). LVR, Loropetalum chinense-Vaccinium bracteatum-Rhododendron simsii scrub- grass-land; LCQ, Loropetalum chinense-Cunninghamia lanceolata-Quercus fabri shrubbery; PLL, Pinus massoniana- Lithocarpus glaber-Loropetalum chinense coniferous-broad leaved mixed forest; LAG, Lithocarpus glaber-Cleyera japonica- Cyclobalanopsis glauca evergreen broad-leaved forest. Different capital letters represent significant differences among different vegetation restoration stages in the same soil layer (p < 0.05), and different lower letters indicate significant differences among different soil layers at the same vegetation restoration stage (p < 0.05).
