Abstract: During 1985-1990 a continuous investigation was carried out in the bamboo (Phyllostachys pubescens) forests at the Dagangshan Experimental Centre, CAF, located in Jiangxi Province,to monitor the structural dynamics of stands. The research results showed that the correlations between DBH(D)and the culm length(H), clear length(HL), crown length(L) and total weight (W) could be expressed in power function,D^b = H (H_L,L,W),where the parameter, a, varies with stem stocking (N)^a of bamboo stands. As the stem stocking rises, the stand productivity will go up, thus the age class distribution within the stand will tend to even out. The differentiation of diameter class generally followed weibull distribution in the stands, however, it would become a normal distribution in some stands with higher productivity.
