Table S4
Fit values of structural equation modeling on the effect of deposited compounds (N, nitrogen; Na, sodium; PAHs, polycyclic aromatic hydrocarbons) and earthworms (micro, without; fauna, with) in deciduous (D) and coniferous forest (C). P indicates the p-value of models, X2/df indicates the ratio of chi-square and degrees of freedom, GFI indicates the goodness of fit, RMSEA indicates the root mean square error of approximation, P_RMSEA indicates the p-value of RMSEA, R2_Loss, R2_SIR and R2_pH indicates the estimate of variances of mass loss, soil microbial biomass and soil pH, respectively.
