Abstract: 49 species, including 42 herbs, 3 shrubs and 4 trees, and 33 species, including 29 herbs, 1 shrubs and 3 trees were recorded in the soil seed bank of a deciduous & evergreen broad-leaved mixed forest and in that of a deciduous broad-leaved forest respectively. The seed density for the former forest was 255 grains/m2 and that for the latter one was 145 grains/m2. Little similarity between the species composition of the soil seed bank and the aboveground vegetation species composition for both forests could be found. 33 species and 413 grains/m2 were observed in the gap part of the soil seed bank for the former forest type, and the similarity in species composition between the gap soil seed bank and the non-gap one was only 53.1%.
