where RCIvc is the relative contribution index of
the vegetation cover to sediment yield.
We explored the interaction between slope gradient and vegetation cover
on
sediment
yield using two-way ANOVA and the relative contribution index in the
SPSS Statistics 17.0 software (SPSS Inc., Chicago, Illinois, USA). All
figures were made in Origin Lab 9.0 software (Origin Lab Inc., USA).
