%X In this paper, the calorific values of Pinus koraiensis-broadleaved mixed forest litters and soil microfauna in China temperate zone were determined, with their seasonal variation patterns studied. The results showed that both the calorific values and their seasonal variation patterns were differed with the kinds of tree species litters and soil macrofauna in the mixed forest. The mean gross calorific value (GCV) of P. koraiensis litter was the highest (19.71 kJ x g(-1)), followed by Betula costata (18.22 kJ x g(-1)), Tilia amurensis (18.13 kJ x g(-1)), mixed litter (17.91 kJ x g(-1)), Fraxinus mandshurica (16.94 kJ x g(-1)), and Acer mono (16.25 kJ x g(-1)). With the decomposition of litter, the GCV of P. koraiensis and A. mono litters decreased, while that of F. mandshurica litter had little change. The GCV of T. amurensis and B. costata litters presented an increasing trend in the next year of decomposition. Among the marofauna, scolopendra had the highest GCV (22.07 kJ x g(-1)), followed by earthworm (16.72 kJ x g(-1)) and diplopod (13.28 kJ x g(-1)). Earthworm and diplopod had the identical seasonal variation pattern of GCV, while scolopendra was different from them. There was no significant relationship between the seasonal variation of GCV in litters and soil macrofauna.
