摘  要:
在收集的36块标准地资料和建立的单株生物量模型基础上,基于非线性度量误差模型方法,对鄂西山区日本落叶松林相容性单株生物量模型进行研究。结果表明,鄂西山区日本落叶松单株生物量平均分配规律呈树干生物量>树根生物量>树冠生物量;所构建的日本落叶松相容性单株生物量模型,确定系数和预估精度均在0.90以上,模型拟合效果较好,预估精度较高,较好地解决了传统模型不相容问题;各组分生物量占总生物量的比例随直径的增大呈不同变化特点,客观反映了林木生物量随直径生长的变化规律。

摘  要:
Based on the data from 36 standard plots and the established individual-tree biomass model,the compatible individual-tree biomass model of Larix kaempferi plantation in western Hubei Mountainous area was studied based on the nonlinear measurement error model.The results showed that the average distribution rule of individual biomass was in a rank of trunk biomass>root biomass>crown biomass;The established compatible individual-tree biomass model of L.kaempferi plantation was above 0.90 in terms of determination coefficient and its prediction accuracy.The model fitting effect was well and the prediction accuracy was high,and it could solve the incompatibility of other traditional models.The biomass proportion of different components in the total biomass showed different characteristics with the increase of diameter and it can provide theoretical basis for the biomass estimation of L.kaempferi plantation in the study area.
