以云南云杉为研究对象，对云杉地上生物量和地下生物量模型进行研建。建立云杉地上总生物量、树干、树冠、干材、干皮、树枝、树叶独立模型与材积相容模型，采用分级联合控制和度量误差模型方法，建立地上总生物量和所有分量相容的立木生物量模型，建立根茎比模型对云杉地下生物量进行估计。结果表明：建立的云杉地上总生物量、树干、干材生物量二元模型预估精度均达95％以上，干皮生物量模型预估精度达94％以上，树冠、树叶、树枝生物量的预估精度均在92％以上，地下生物量模型预估精度在88％以上；所建立的模型可以用于云杉生物量的估计。

In this paper, the approach on establishment of above-ground and below-ground single-tree biomass equations of sprucewas studied. First we established itstotal above-ground, stem, crown, stem wood, stem bark, branches, leaves independent biomass models and compatible with the volume biomass models. Then a system of spruce biomass models was established, in which the total above-ground biomass equationswas compatible with stem, crown, stem wood, stem bark, branches, leaves biomass equationswas successfully established by classification control scheme and error-in-variable model method. Finally a root-shoot ratio model was build up, which could be used to estimate below-ground biomass together with above-ground biomass equation. The results showed that：the prediction precision ofabove-ground biomass, stem, stem woodweremore than 95 %, stem bark was more than 94% and was more than 92% for crown, branches,leaves biomass estimation respectively, the prediction precision of below-ground biomassmodel was more than 88% , all models were recommended to be applied to biomass estimation ofspruceforests.
