  • Shrub biomass is frequently estimated by modeling methods.In this paper,we es-tablished biomass models using height and basal diameter as variables for twelve common under-forest shrubs in Jinggangshan Nature Reserve.We compared the value of R 2 to choose the best model for biomass estimation.Three equations W=a+bx12,W=a+bx+cx2,and W=a xb had high related coefficient.When we simulated biomass,the values(R 2) reached a significant level and equaled 0.904-0.991.The three equations can be used to estimate actual biomass of shrubs.However,the equations W=a+bx,W=a+bx1+ cx2 and W=a+b ln X showed poor accuracy.Building models must have high precision and be easy to use as it is important to estimate biomass of shrubs as it relates to factors such as carbon storage.
