Abstract: The annual litterfall production, composition and decomposition of the litterfall of six typical stands in Maoershan, Heilongjiang Province were studied in this paper. The results are as follows: (1)the annual litter production is in the sequence of Pinus koraiensis (5.62 t·hm-2), Fraxinus mandshurica(5.57 t·hm-2), Pinus sylvestris(5.56 t·hm-2), Quercus mongolica(4.31 t·hm-2), Populus davidiana(4.27 t·hm-2),Larix gmelinii(4.08 t·hm-2); (2) the fall of leaves of six forests occupies a higher percentage in the annual total litterfall than that of other components; (3)decomposition rates of leaf litter in the six forests obvious: Fraxinus mandshurica > Pinus sylvestris > Larix gmelinii > Populus davidiana > Quercus mongolica > Pinus koraiensis.The simulated time spans needed for 95% weight loss of litter in Fraxinus mandshurica, Quercus mongolica, Populus davidiana, Larix gmelinii, Pinus koraiensis, Pinus sylvestris stand were 3.5, 8.0, 6.7, 6.6, 8.8 and 4.4 years, respectively.
