Abstract:
Fitted with component biomass data of individual trees with variable allometric rates model for armosia xylocarpa plantation stands in 22-year-old, the result showed that total stand biomass was 165. 165 t/ha, crops were 161. 571 t/ha, average net production was 8. 983 t/(ha ?a) (Crops were 7. 344 t/(ha ?a)). Components biomass were 83. 572, 40. 039, 13. 526 and 24. 474t/ha for stem (wood and barks), branches, leaves and roots respectively. Based on the DBH, the result from tree hight and timber volume data of analysis tree with Logistic increment equation showed that fast growing stage was 9-12, 9-14 and 15-17 year-old for DBH, tree hight and timber volume respectively.
