Figure 8

Comparison of soil separation rate \({D}_{r}\) between four litter decomposition stages. \({D}_{r}\) is the rate of soil separation; N1–N7 are treatments, see Table 2 for treatment specifics; T1 is slope 5°, rain intensity 60 mm·h⁻¹; T2 is slope 10°, rain intensity 60 mm·h⁻¹; T3 is slope 5°, rain intensity 120 mm·h⁻¹; T4 is slope 10°, rain intensity 120 mm·h⁻¹. ND is non-decomposed state, ID is initial stage of litter decomposition, MD is middle stage of litter decomposition, FD is final stage of litter decomposition.
