摘要
根据样地调查获得的数据,选择已建立的各种相关生物量预测模型进行统计,对千岗坑林区分别不同的阔叶林类型进行生物量的测定研究,结果表明,4个主要类型由于树种组成和林龄的不同,其直径分布变异较大,在生物量上阔杉混交林生物量最高达337.3t/hm2,常绿与落叶阔叶林的生物量最低为166.0t/hm2,在各类型的生物量组分中,树干组分的比例最大,其次为枝,再次是根,最低是叶。而生态功能的强弱序列为常绿阔叶林>常绿与落叶阔叶混交林>阔松混交林>阔杉混交林,木材生产能力的大小序列为阔杉混交林>阔松混交林>常绿阔叶林>常绿与落叶混交林。
Determination on biomass of different broad-leaf stand types in Qiangangkeng, Qingyuan Forest Center of Zhejiang province resulted that diameter distribution had significant difference because of different tree species and age composition of 4 stand stands. Mixed forest of broad-leaf and Cunninghamia lanceolata had biomass of 337.3t/ha, while evergreen broad-leaf and deciduous had only 166.0t/ha. The ratio order of tree component in the biomass was as follows: trunk>branch>root>leaf, while ecological function of forest type ordered as: evergreen broad-leaf>mixed forest of evergreen broad leaf and deciduous broad leaf>mixed forest of broad leaf and pine>mixed forest of broad leaf and C. lanceolata, timber yield ordered: mixed forest of broad leaf and C. lanceolata> mixed forest of broad leaf and pine> evergreen broad-leaf>mixed forest of evergreen broad leaf and deciduous broad leaf.
