| 摘 要： | 通过对白桦天然次生林中15株树龄16~54年标准木的研究,建立了以D和D2H为基础的林木全株及器官生物量估测模型,林木单株生物量变化为17 361.7~364 634.7g,白桦的根茎比变化为0.210~0.465,平均值为0.320;建立了以林龄为基础的生物量估测模型,对其多年平均净生产力与年均净生产力进行了研究,认为20年左右林木进入速生期时应加强抚育。

| Abstract: | Based on the investigation of 15 standard trees in Betula platyphylla natural secondary forest which of tree age were bewteen 16 and 54,the individual biomass chang from 17361.7 to 364634.7g.The biomass equations of tree and tree organs are found which based on the D and D2H.The root-shoot ration chang from 0.210 to 0.465,the average was 0.320.The biomass equations were found based on the tree age,the net productivity for many years and every year were studied.It showed that fast growing period was after 20... |
