    Abstract:
    The storage, biomass, and decomposition of fallen woods in dark coniferous forest on the north slope of Changbai Mountain at elevations of 1260 m and 1620 m were studied. The results showed that the volume of fallen woods was 180.87 m3.hm-2, occupying 21.83% of the stand volume. The volume and biomass of fallen woods at elevation of 1260 m were higher than those at 1620 m. The volume of fallen woods was 52.57 m3.hm-2 at 1260 m, and was 193.85 m3.hm-2 at 1620 m, and their biomass was 6.21 t.hm-2 at 1260 m, and was 53.33 t.hm-2 at 1620 m. Monomial exponential attenuation model could be used to simulate the decomposition process of fallen woods. The results indicated that the decomposition constants of fallen woods were different among different tree species and different elevations. The decomposition constant of fallen woods of Abies was higher than that of Picea, and was higher at 1260 m than at 1620 m. The results also showed that the decomposition of Picea lasted longer.
