Based on the biomass data from 140 sampled shrubs of Philadelphus schrenkii, Acanthopanax senticosus, Corylus mandshurica, and Sorbaria sorbifolia, the total biomass and univariate and bivariate additive biomass models of each component for the four main shrub species in Xiaoxing'an Mountains was developed. Using the allometric equations as the base model, the likelihood analysis was employed to determine the error structure of organ-specific biomass models. Optimal biomass models for individual organs were integrated with aboveground and total biomass equations to form a system of simultaneous equations, which was fitted using the seemingly unrelated regression. The established additive biomass models for four shrub species were evaluated using the leave-one-out cross-validation method. The results indicated that log-transformed linear regression validated by the likelihood analysis was suitable for modeling organ-specific biomass of four shrub species. Incorporating height improved the predictive accuracy of the additive biomass models. The optimal additive models exhibited adjusted values ranging from 0.7062 to 0.9831, with mean absolute percentage errors between 13% and 42%. The models for total biomass, aboveground biomass, and stem biomass demonstrated superior performance compared to those for foliage and root biomass.
