摘　　要：采用样地法对嵩山地区侧柏10,17,21,31,44,65龄人工林的生物量和生产力进行了调查.结果表明:在不同林龄的侧柏人工林中,其单株侧柏各器官生物量的分配规律均为树干>树枝>树叶;不同恢复时期侧柏人工林乔木层的各部分器官生物量以及地上部分总生物量随林龄的增长都呈增加的趋势,但不同时期的生产力不同.The biomass and productivity of Platycladus orientalis plantation of different ages were discussed in the Songshan Mountains National Forest Park. By investigating 12 arbors plots, the results showed as following： At age-dependent plantation, the biomass of organs of Platycladus orientalis tree showed such a regularity as stems〉 branches〉leaves; The different part and the total biomass of Platycladus orientalis plantation increased with age,however, the productivity were very different at the different aged P. orientali plantations.
