Abstract: The study shows that in Maoer Mountain, the rates of litter decomposition and consumption were higher in pure Pinus koraiensis-forest than in P.koraiensis broad leaved mixed forest. In the course of litter decomposition and consumption, soil animals, and soil macrofauna in particular, played more important role than soil microbes. The seasonal variation curves of soil animal species and individuals were similar to those of litter decomposition and consumption rates, with the peaks in July, which indicated that the decomposition and consumption of litter was correlated with soil animals.
