%X Samples were collected from dark-brown forest soil in different depths in the virgin broad-leaved/Korean pine mixed forest in Changbai Mountain. Laboratory study on methane oxidation of forest soil revealed the vertical profiles of methane oxidation activity. The maximum methane oxidation occurred at the horizon 5-15 cm below the soil surface. When incubated with 400 ppmv methane, it had the highest uptake rate of 3.3 nmol.h-1.g-1 dw. Soil at horizon below 25 cm had a negligible capacity to oxidize methane. The methane-oxidation capacity of surface soil (0-5 cm) decreased because of the inhibition effect of high concentration NH4+ on methanotrophs.
