**Figure A1.** Correlations between litter and soil C, N and P of four dominate species with two different functional types (Gramineae *Lophatherum gracile* and fern *Woodwardia japonica*, *Dryopteris atrata* and *Dicranopteris dichotoma*) in CK treatment.

**Figure A2.** Correlations between litter and soil C, N and P of four dominate species with two different functional types (Gramineae *Lophatherum gracile* and fern *Woodwardia japonica*, *Dryopteris atrata* and *Dicranopteris dichotoma*) in N addition treatment.
