Abstract: Based on the data of biomass and stem analysis of 20-year-old Bruguiera gymnorrhiza, the grey model(1,1) in the grey system theory is used to forecast the individual organ biomass of the tree and their precisions predicted of the grey model(1,1) are compared with those of the nonlinear regressive equation. The results show that grey model(1,1) can be used to predict accurately but the nonlinear regressive equation, owing to the existing major error, can not be applied. Biomass forecast in the near future is made in order to provide a theoretical basis for managing and utilizing Bruguiera gymnorrhiza stand rationally.
