EStablishment of Biomass and Volume Tables for Acacia auriculiformis

In order to find out the simple method for estimation of biomass and volumeprdocuction of Acacia auriculiformis plantations, this paper selected two models of W(V)1=aDb and W(V)2=a(D2H)b to establish two groups of regression equations that can be usedfor the estimation of the biomass,components(stem,branch and leaf),total above groundbiomass and volume production based on the data of sample trees collected in the fuelwoodresearch.Comparison of the two groups of equations showed that the first model was thebest fit model.Its precision was high and its independent variable(D)was an easy-to-measure parameter that can further improve the precision of estimation.So the biomass andvolume tables were established based on the regression equation drawn from the first model.
