摘　　要：对云南省水富县引种撑绿竹的不同径阶生物量进行了测定,结果表明:撑绿竹各构件的生物量随径阶的增大而逐渐增大,其分布规律是:秆>枝>叶>蔸>根,且生物量与胸径相关性显著,采用回归模型W=355 6.98+0.337 89(D2H)可较准确地预测单株生物量,该模型在生产中具有广泛的应用价值。The biomasses of different diameter classes of introducing Bambusa pervariabilis × Dendrocalamopsis grandis were surveyed in Shuifu County. The results showed that the biomasses of different parts of B. pervariabilis × D. mopsis grandis were increased with the increase of diameter classes, and the order of the biomass of various parts was. culm 〉 branch 〉 leaf 〉 bamboo stake 〉 root. The relationship between biomass and diameter of B. pervariabilis × D. mopsis grandis was significantly, and the regression model, W = 3 556. 98 ＋ 0.337 89 （D^2H） , could be used to accurately predict the individual biomass, and this model would be expected to be applied in practice extensively.
