Study on the Individual Tree Biomass of Larix kaempferi Plantation in Xiaolong Mountain, Gansu Province

  • Received Date: 2010-11-08
  • By using the methods of regression analysis and model optimal selection, the biomass of each organ of Larix kaempferi was measured, and the biomass equations for L. kaempferi in Xiaolong Mountain of Gansu Province was built. The results showed that: The average biomass of young, immature, nearly mature, and mature forest of L. kaempferi were 3.617,29.846,123.954,and 177.482 kg. The biomass ratio of the stem, roots, branches, bark, leaves of different-aged L. kaempferi were 32∶ 17∶ 23∶ 11∶ 17 (young growth);50∶ 20∶ 15∶ 10∶ 5 (immature);62∶ 15∶ 10∶ 9∶ 4 (nearly mature);and 58∶ 23∶ 9∶ 8∶ 2 (mature forest).The biomass between DBH, height and various components, between each component and root and needle, and between aboveground and underground were significantly correlated. The final prediction model of individual tree biomass is lnWtotal=-1.916 4+0.768 11 ln(D2H) and the value of R2 is 0.986.
