摘　　要：以江西瑞金林区毛竹林为研究对象,对不同龄级毛竹各器官生物量回归模型进行研究。结果表明:不同龄级毛竹生长特性的差异影响其生物量分配,毛竹各器官生物量分配比例表现为竹秆(56.91%)>竹蔸(15.96%)>竹根(10.48%)>竹枝(9.53%)>竹叶(7.12%)。毛竹各器官生物量之间及其与胸径和秆高均具有较好的相关性,建立了基于立竹胸径和高度的各龄级毛竹各器官生物量回归模型。Taking Phyllostachys edulis forest as the research object in Ruijin County,Jiangxi Province,the regression models of biomass of various organs of Ph.edulis at different age classes were studied.The results showed that the biomass allocation of different age classes of Ph.edulis were affected by growth characteristics.The biomass allocation proportion of each organ of Ph.edulis was as follows:bamboo stalk(56.91%)>bamboo stump(15.96%)>bamboo root(10.48%)>bamboo branch(9.53%)>bamboo leaf(7.12%).There was a good correlation between the biomass of each organ and DBH and culm height of Ph.edulis.The regression model of biomass of each organ of Ph.edulis based on DBH and culm height was established at different age classes.
