Figure 1 . Physical properties of the soil. The soil was sampled
at different depths (a), at different slope positions (b), and in
different forest types (c). SMC (%), soil moisture content; EC
(µs·cm−1), electric conductivity; TDS
(µg·L−1), total dissolved solid; GS
(g·cm−3), specific soil weight. Forest types: NA,Camellia oleifera new afforestation; GLF, Gardenia
jasminoides in a low-yielding C. oleifera forest; LF,
low-yielding C. oleifera forest; GNA, G. jasminoides inC. oleifera new afforestation. Twenty, soil layer at 0–20 cm
depth; Forty, soil layer at 20–40 cm depth; Sixty, soil layer at 40–60
cm depth. The data are shown as the mean ± SD. (depth and slope positon
n = 9forest type n = 12; *P < 0.05, **P< 0.01, ***P < 0.001). Statistical analysis
was performed using one-way analysis of variance (ANOVA), and Tukey’s
multiple comparison test was used to correct for multiple comparisons.
