Responses of Soil Organic Carbon to Long-Term Understory Removal in Subtropical Cinnamomum camphora Stands

Table 1

General characteristics of experimental plots (mean ± SD, 𝑛 = 10).

Stand type	Main plant species	Tree height (m)	DBH (cm)	Stem density (trees·hm^−2)	Stand age (year)	Canopy density	Slope aspect	Understory vegetation
UR	Cinnamomum camphora	13.5 ± 1.07	18.96 ± 1.98	917 ± 88	48	0.9	south	With few shrubs and a few herbs
CK	Cyclobalanopsis glauca and Loropetalum chinensis	10.0 ± 0.59	10.58 ± 2.62	1658 ± 300	48	0.9	south	With lots of shrubs and herbs

UR: understory removal; CK: control; DBH: diameter at breast height (the same as below).
