为了解偃松单木地上生物量及其分配模式，采用嵌套回归法对偃松伐倒木进行调查，用异速生长方程建立各组分的独立生物量模型，并对模型进行相容性处理。结果表明：偃松单木各组分相容性生物量模型的拟合效果均显著，决定系数均大于0．80。

For clarifying the aboveground biomass and its allocation pattern of Pinus pumila trees, we surveyed felled trees by u -sing the nested regression method.Independent component biomass models were established with the allometric growth model, and model compatibility was dealt afterwards.The fitting effects of compatible models for each component were all significant with the determination coefficients of more than 0.80.
