摘要: 本文对黑龙江省绥棱林区红皮云杉人工林的生物量和净生产量进行了测定和研究。按平均标准木法调查并分析了林龄为6~31年红皮云杉人工林乔木层干、皮、枝、叶、根的生物量、净生产量及其分配.用维量分析法建立了估测乔水层单株林木各器官生物量的回归方程, 方程的相关系数和估测精度较高, 具有参考价值。分析结果表明:红皮云杉人工林乔木层生物量随年龄的增长而增加, 到31年生, 林分总生物量平均为151.13t·hm-2, 净生产量并不是随着年龄规律是增长, 积累速度快慢不一, 一般在30年左右其净生产量值为11~14t·hm-2·a-1, 表明红皮云杉人工林群落具有较高的生物生产力。

Abstract: In this paper, the biomass and net production of Picea koraiensis artificial forestsof Suiting, Heilonajiang Province are measured and studied According to the "averagestandard tree", the biomass, net production and its distribution of the trunk, bark, branch, leaf e and root of the Picea koraiensis artifical forests of 6-31 years old areanalysed. The regression equation for the estimation of the dry weight of each organis founded by the dimension analysis. The relative coefficient of equation and themeasurement precision are high. The results shows: with the increase in age. thebiomass of Picea koraiensis artificial forests increase. At the age of 31 years old.the average biomass of forest is 151. 13t. hm-2, The net production doesn't relatewith the age. Usually, at the age of 30 years old, the net production is 11-14t. hm-2. a-1 Thus, the community of Picea koraiensis artificial forests possesseshigh biological production.
