Data are presented as mean ± SD (depth and slope positon n = 9, forest type n = 12). Different lowercase letters in the same column represent significant differences at P ≤ 0.05, and different uppercase letters represent significant differences at P ≤ 0.01. One-way ANOVA was used for the statistical test. NA, Camellia oleiferanew afforestation; GLF, Gardenia jasminoides in a low-yieldingC. oleifera forest; LF, low-yielding C. oleifera forest; GNA, G. jasminoides in C. oleifera new afforestation. TOC, total organic content; HC, humus content; SOM, soil organic matter; TN, soil total nitrogen; TC, soil total carbon.
