摘　　要：对南靖林场5a山地麻竹林生物量、生产力及能量结构进行了研究,结果表明,麻竹林现存生物量、能量贮量和移出林外利用的生产力随林龄的增大而增大,3a以后竹林地下部分生物量、能量贮量大于地上部分生物量,林下植被生物量和能量随竹龄增大而减小,1、2a竹林林下植被能量贮量高于麻竹林层;麻竹林各组分的热值为17 2059～20 2806kJ·g-1,灌木的最高,地表残留物的最低。Through measuring biomass,productivity and energy structure of different-aged Dendrocalamus latiflorus plantations planted on mountainous areas,results showed that biomass,productivity and energy structure tended to increase with the age of stand.In the stand aged over three,the structures of the biomass and energy on ground were larger than those under ground.Biomass and energy of vegetation under forest tended to decrease with the age of stand,energy store of vegetation layer were larger than that of arbor layer in one-year-old and two-year-old plantations.Energy value of different groups of forest ranged from 17.205 9 to 20.280 6 kJ·g^(-1),the largest was shrub layer,the lowest was litter layer.
