| 摘 要： | 森林是陆地生态系统的主体,在全球陆地生态系统碳循环和碳储量中占有十分重要的地位(Dixon et al.,1994;Watsonetal.,2000;史军等,2004;徐新良等,2007)。测定森林群落生物量,可以反映群落利用自然的潜力,衡量群落生产力的高低,也是研究森林生态系统物质循环的基础(薛立等,2004)。森林乔木层生物量研究是开展森林群落生物量碳库研究的基础,国内外已有不少该方面的研究,分别从不同角度分析了树种生物量的组成与分配特征,并进行了相关因子分析(Chidumayo,1990;林开敏等,1996;Arashkevich et al.,2002;樊后保等,2006;陈美高,2006)。冯宗炜等(1999)总结了全国不同森 |

| Abstract: | Biomass allometric equation and allocation pattern was collected from 10 trees each of three dominant tree species (group), Pinus massoniana, Cunninghamia lanceolata and the natural evergreen broadleaf species (groups) were researched by full harvest method. The results showed that the fitted precision with one-independent-variable allometric equation was better than two-independent-variable allometric equation. The biomass proportion accounted for more than 60% of the total tree biomass, with 68.36%±5.81% in P. massoniana, 63.61%±3.24% in C. lanceolata , and 61.92%±6.72% in the evergreen broadleaf tree species. The proportion of branch biomass to whole tree biomass showed a trend as follows: evergreen broadleaf tree species (groups) (14.65%±4.766%) > P. massoniana (11.23%±3.40%) > C. lanceolata (8.69%±1.77%). The proportions of root biomass to whole tree biomass had an order: C. lanceolata (19.25%±2.56%)> the evergreen broadleaf tree species (17.71%±6.63%) > P. massoniana (17.34%±3.92%). The proportion of leaf biomass to tree biomass showed a trend as follows: C. lanceolata (8.11%±1.51%) > the evergreen broadleaf tree species (5.03%±1.48%) > P. massoniana (3.40%±0.81%). The ratio of root to stem in the three tree vegetables fluctuated from 0.20 to 0.25, there was no significant difference over the vegetables. |
