摘　　要：为合理经营管理油松林,对八达岭林场30 a生油松林的生物量进行了研究。结果表明:30 a油松林的总生物量为69.52 t/hm2,其中乔木层为68.11 t/hm2,灌木层为1.4 t/hm2,草本层为0.27 t/hm2。乔木层各器官生物量所占比例的顺序为干>根>枝>叶,且林木全株生物量以及各器官生物量与胸径和树高建立的回归方程相关系数都在0.90以上。The biomass of 30 year-old Pinus tabuia（ormis forest is studied for reasonable management in Badaling Tree Farm. Results show that the biomass of Pinus tabuiaeformis forest in the farm is 69.52 t/hm^2 ,and the distribution of biomass is mostly in the arbor layer, which is about 68.11 t/hm^2, the shrub layer and the herb layer are 1.14 t/hm^2 and 0.27 t/hm^2. To the arbor layer biomass, the think, the branch, the leaf and the root in proper order is tnmk〉 root 〉 branch 〉 leaf, the correlative coeffident of regression equation which is established between total biomass,each biomass and D^2H is higher than 0.90.
