摘　　要：为了探究华北落叶松的生物量最优生长模型,以承德围场县北沟营林区华北落叶松人工林为研究对象,通过设置标准地,对其17-43a生林分进行详细调查,利用Spass曲线估计方法,最终确定其生物量估算模型。结果表明：二次函数为生物量最优模型,地上总生物量W总=-53.846-0.486 D＋0.558 D2,树干生物量W干=-65.067＋2.648 D＋0.312 D2,树枝生物量W枝=-0.701＋0.024 DH-4.868×10-6（DH）2,树叶生物量W叶=-2.205-0.479 D＋0.066 73 D2,树皮生物量W皮=-3.536＋0.004 D2 H-7.998×10-8（D2 H）2。In order to explore the optimal biomass estimation model of Larix principis-rupprechtii,the detailed investigation on Larix principis-rupprechtii plantation of Beigou forest area of Weichang County in Chengde City as the research object was conducted by setting the standard of the 17-43astand and the biomass estimation model was ultimately determined by using the estimation method of Spass curve.The results showed that the quadratic is the optimal biomass estimation model,with the total above ground biomass W 总 =-53.846-0.486 D＋0.558 D2,the trunk biomass W 干 =-65.067＋2.648 D＋0.312 D2,the branch biomass W 枝 =-0.701＋0.024 DH-4.868×10-6（DH）2,the leaf biomass W 叶 =-2.205-0.479D＋0.066 73D2 and the bark biomass W 皮 =-3.536＋0.004D2 H-7.998×10-8（D2 H）2.
