| 摘 要： | 以枝、叶、根等构件种群为基本构件单元,结合其它指标,对不同生境的4年生猴樟构件种群生物量的差异及变化规律进行了研究。结果表明:同一生境下,4年生猴樟老枝生物量的变化规律均表现为:一级枝>二级枝>三级枝>四级枝。而对于新生枝生物量的变化规律来说,林中和孤立木均为:二级枝>一级枝>三级枝,而林缘略有差异。不同生境下,根的平均长度、平均粗度、总长度、生物量的变化规律大体上均为:孤立木>林缘>林中,只是一级根在生物量和总长度上出现了孤立木>林中>林缘。

| Abstract: | The difference and change rule of modular population of branch,leaf,root of 4-year-old Cinnamomum bodinieri were studied in different habitats.The result showed that in the same habitat the change rule of old branch biomass is in the order of primary >secondary branch>tertiary branch> quaternary branch.The change rule of new branch biomass in forest center and isolation habitats is in order of secondary > primary branch>tertiary branch,while that in forest edge is slightly different.In different habitats,the average length,diameter,total length and biomass of root are all in the order of isolated >forest edge>forest center,whereas the biomass and total length of first-grade root is in the order of isolated> forest center >forest edge. |
