Biomass Characteristics of Dominant Tree Species (Group) at Lingnan Forest Farm in Anhui Province
摘要
Abstract
Biomass allometric equation and allocation pattern was collected from 10 trees each of three dominant tree species ( group) , Pinus massoniana, Cunn.in.gh.amia 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.关键词
