Abstract: Based on the measurement data of aboveground biomass from 604 sample trees and underground biomass from 212 sample trees of Chinese fir(Cunninghamia lanceolata)and Masson pine(Pinus massoniana)in southern China,the single tree above and under ground biomass models involving forest origin were constructed by using nonlinear mixed model and dummy variable model approaches,and the impact of forest origin on biomass models was analyzed.The results showed that the aboveground biomass models for different origins had no significant difference,while the underground biomass models were significantly different,from which the underground biomass estimate of natural tree with same diameter and height was highly greater than that of planted tree.Specially,the underground biomass estimates of natural trees are nearly 30% and about 45% greater than those of planted trees for Chinese fir and Masson pine respectively.
