Abstract: Biomass Model is one of the important methods used to estimate the shrub biomass.Little attempt has been tried to systematically investigate the biomass in shrublands compared with that in forest and grassland ecosystems because of the harsh conditions to carry out field work.In this study 4 common mathematical models (monadic linear model,binary linear model,logarithmic function model and power function model) and 3 prediction variables (height,H; canopy,C; and volume,V) were used to establish the equations for estimating the biomasses of 26 common temperate shrub species in Inner Mongolia,and the R/S ratios of these shrub species in different habitats were compared.The results showed that: ① The power function and linear function models were the main models used for estimating the biomass,and C and V were the optimal predictors; ② The optimal equations and their prediction variables for estimating the biomasses of different organs of 17 shrub species were the same,which indicated that the equation forms for estimating the biomass were similar.However,the coefficients for different organs in the model were different,it was more accurate to estimate the biomass by using the species-specific biomass equations for each species and organs; ③ The R/S ratio of shrub species in grassland and mountainous habitats was significantly higher than that in desert habitat.Through developing the biomass models and studying the R/S ratios of common temperate shrub species in Inner Mongolia,the vegetation biomass and carbon storage of the shrubland ecosystem in Inner Mongolia could be conveniently estimated.
