| 摘 要： | 在福建柏人工林生物量中 ,乔木层占主要部分 (90 %以上 ) ,其次是枯枝落叶层 ,下木活地被物层最小 ;林分总生物量、乔木层、凋落物层生物量随年龄的增大而增大 ,下木活地被物层随郁闭度的增加而减少。不同龄级的福建柏林分生产力差异明显 ,以Ⅵ龄级的林分生产力最大 ,生产力的总趋势随龄级的增加而增大 ,至Ⅵ龄级后又减少。福建柏人工林胸径与枝叶重、干重、枝重、叶重呈极显著相关 ,结合树高因子 ,可建立相关方程W =aDbHc。

| Abstract: | In the biomass of Fokienia hodginsii plantations,the biomass of the arbor layer accounts for over 90% of that of a whole tree,the biomass of the litter layer occupies the second place,and the biomass of the understorey living ground cover layer is the smallest.The stand total biomass,arbor layer biomass and litter layer biomass increase with the increase of age whereas the biomass of the understorey living ground cover layer decreases with the increase of shade density.The productivity difference of different age class F.hodginsii is evident. |
