To study the comparison of the aboveground biomass of Robinia pseudoacacia L. of 8-, 13- and 20-year-old plantations, the experimental plot of 100㎡ in size located in Youngin-gun were selected. Seven sample trees at different stand ages selected taking account of DBH distribution were felled and the diagram of oven-dry weight distribution of stem, branch and leaf for each 1m segment was constructed. The dry weight of each part of plots was estimated by the method of basal area ratio. If the estimations are extended to a hectare area stand, it contains 36.72, 69.28 and 118.67 tons of the aboveground standing crops in 8-, 13- and 20- year-old stand respectively. The net production was estimated to be as much as 12.56, 13.23 and 16.78 tons per hectare per year and the net assimilation ratio 3.66, 4.13 and 2.50 ㎏/㎏/yr in 8-, 13- and 20-year-old stand respectively. And the efficiency of leaves to produce stem was 1.69, 2.10 and 0.96 ㎏/㎏/yr in same order.
