摘要
用回归分析方法 ,对我国亚热带湖南会同红栲 青冈 刨花楠群落的生物生产力进行了研究 ,结果表明 ,林分总生物量为 45 1.0 2t·hm-2 ,其中乔木层、灌木层和藤本生物量分别为 42 6 .76、17.76和 1.80t·hm-2 ,枯枝落叶层现存量为 4.70t·hm-2 ,乔木层净生产量和平均生产量分别为 34.46t·hm-2 ·年 -1、13 .32t·hm-2 ·年 -1.
Based on the mean DBH measurements of sample trees,the bioproductivity of subtropical Castanopsis hysrix Cyclobalanopsis glauca Machilus pauhoi community in Huitong, Hunan province was studied by regression analysis (y=a(D 2·H) b). The results showed that the total biomass of the forest was 451.02 t·hm -2 , and the component biomass of tree, shrub, liana and litter layer was 426.76,17.76,1.80 and 4.70t·hm -2 , respectively. The net production and average production of tree layer were 34.46 and 13.32 t·hm -2 ·yr -1 ,respectively.
