Abstract: In order to understand the community ecology process of Fargesia and explore the carring capacity of panda habitat,studies were made of on the biomass distribution pattern of above-ground organs of three kinds of Fargesia and the regression models of each biomass component were also based on BD and culm height. The results showed that:(1) among the above-ground organs, the culm biomass was much more than the branch and leaf biomass. In the culm biomass allocation, Fargesia angustissima > Fargesia nitida > Fargesia scabrida. In the branches biomass allocation,Fargesia scabrida > Fargesia angustissima > Fargesia nitida. In the leaf biomass, Fargesia scabrida > Fargesia nitida > Fargesia angustissima. (2) Various components were highly correlated with BD. The models of fresh culm weight(W₁) based on BD of the three Fargesia species were W₁=1/7.761 + (-29.385e^-B)(Fargesia angustissima), W₁=0.367B^2.614(Fargesia nitida), W₁=1/4.804 + (-11.414e^-B)(Fargesia scabrida). According to these models the community biomass of those three Fargesia species could be accurately estimated,and thus the carrying capacity of panda habitat could also be estimated.
