Abstract: To replenish the understory biomass of shrubs and herbs and to provide a more detailed dataset,this study analyzed biomass models which to fit and estimate sapling biomass of primary species in the under-story of the Changbai Mountains. Three Picea jezoensis and Abies nephrolepis (spruce-fir) forests classified according to their canopy densities of 0.6,0.8,and 1.0,sixty 5 m5 m plots were designed,five species (including Tilia,Pinus,Abies,Acer,Picea) were sampled. Results showed that the organ biomass models (for trunk,branches,leaves,and roots) of the primary spruce-fir species was most closely associated with independent variables D2H (where D is basal diameter and H is tree height) and DH with the optimal models being linear functions,coefficient of determination was above 0.85,all functions were significance (P<0.05). In addition,an increase in canopy density,sapling biomass (dry weight) performanced for the W(1.0)>W(0.6)>W(0.8). Also,for canopy densities of 0.6,0.8,and 1.0,fir saplings contributed the most biomass 34.94%,40.79%,and 50.26%,respectively; whereas biomass from spruce saplings contributed the least with 6.03%,8.58%,and 8.03%,in that order,we can predict biomass changes in the different canopy density,and enrich understory biomass for this area.[Ch,1 fig. 4 tab. 16 ref.]
