摘要: 对渝东重庆石柱林场不同林龄(8 a、20 a、30 a)马尾松生长及生物量分配状况研究,结果表明:①马尾松的胸径和树高在幼龄林(8a)和中龄林(20a)生长速度最快,材积量则在成熟期(30a)达到最大。②马尾松各器官生物量和总量随着林龄的增加而增加,树干的生物量增长速度最快,在成熟期最高,达到72.68%。③各林龄马尾松林内,各层次生物量的高低排序都为乔木层、枯落物层、草本层、灌木层;乔木层生物量和林地地上总生物量均随着林龄的增加而增加,并占有绝对的优势;灌木层、草本层和枯落物层占地上部分总生物量比重则逐渐降低。④马尾松林的地上部分各林层的净生产力在中龄林的高低排序都为乔木层、枯落物层、草本层、灌木层,幼龄林和成熟林则表现为乔木层、草本层、枯落物层、灌木层;乔木层生产力在地上总生产力中占绝对比重。

Abstract: Research was conducted on the status of Masson pine's growth and biomass allocation at different forest ages (8 years,20 years,30 years) in Shizhu State Forest Farm of East Chongqing. The results showed that ① the DBH and tree height of Masson's pines grew the fastest at young age (8 years) and the middle age (20 years), the timber volume reached the maximum at maturity (30 years). ② Masson's pine's various organs and total biomass would increase along with the increasing of the stand age,the trunk biomass had the fastest increase velosity,and was the highest at the maturity,reaching 72.68%. ③ Within each Masson's pine age,the sorting of all levels of biomass was as follows:tree layer, litter layer, herb layer,shrub layer; tree biomass and forest floor layers' total biomass would increase with increasing age and had an absolute advantage; shrub, herbaceous layer and litter layer occupying the proportion of the total biomass decreased. ④ The sorting of aboveground net primary productive forces of each Masson's pine layer level at the middle-aged forest was as follaws tree layer,litter layer,herb layer,shrub layer. And yet in young forest and mature forest, the sorting was tree layer > herb layer > litter layer > shrub layer; tree layer productivity accounted for the absolute proportion of the total above ground productive forces.
