A 50-year-old Quercus mongolica stand and a 49-year-old Quercus variabilis stand in Chuncheon, Kangwan-do were studied to compare their biomass, net production and production efficiency including roots and undergrowth. Total biomass of Q. mongolica stand was 500. 28t/ha and net production was 21.85t/ha/yr. Total biomass of Q. variabilis stand was 321.19t/ha and net production was 17.33t/ha/yr. Biomass accumulation ratio was 22.90 for Q. mongolica stand and 18.53 for Q. variabilis stand. Net assimilation ratio ws 4.05 for Q. mongolica stand and 5.17 for Q. variabilis stand. Since Q. mongolica stand had more leaf biomass than Q. variabilis stand, the former showed a higher total biomass even though its net assimilation ratio was a little lower than the latter.
