An investigation of stand biomass and productivity was undertaken of Eucalyptus urophylla planted at spacing of 2 mx3 m in 1990 on Dongmen State Forest Farm, Guangxi Province, China. Stands in 27 plots with 20 m x 24 m each were measured, and 9 individual sampling stands from each diameter class were chosen. Regression equations for predicting biomass production were developed using functional dependence of biomass in different plant components on D2H. Mean biomass production of 10-year-old single tree and
