| 摘 要： | 对福建省连城邱家山国有林场9年生秃杉人工林地上部分和地下部分生物量及其分配规律进行研究。结果表明,9年生秃杉人工林平均胸径、平均树高及总生物量均表现为下坡位〉中坡位〉上坡位;就各器官生物量而言,不同坡位平均木叶和干生物量表现为下坡位〉中坡位〉上坡位,枝生物量表现为中坡位〉上坡位〉下坡位,骨骼根、大根、中根生物量表现为下坡位〉中坡位〉上坡位,小根和细根生物量为上坡位〉中坡位〉下坡位。就各器官生物量分配率而言,不同坡位秃杉人工林各器官生物量分配率表现为干〉叶〉枝,上坡位和下坡位均表现为骨骼根〉大根〉中根〉粗根〉小根〉细根;中坡位则表现为骨骼根〉大根〉粗根〉中根〉小根〉细根。

| Abstract: | The distribution and the above and under ground biomass of nine-years-old Taiwania flousiana plantation in national farmland in Qiujiashan in Liancheng County were studied in this paper.The result showed that the average DBH,average tree height and total biomass of Taiwania flousiana plantation were as follow:lowslope>midslope>upslope;as for the biomass of different organs,leaf and trunk biomass were:lowslope>midslope>upslope;Branch biomass was:midslope>upslope>lowslope;stump root,big root and middle root b... |
