%X 华北落叶松是我国东北部主要针叶树种之一，研究华北落叶松人工林的生物量对提高林分生态价值具有重要作用。采用固定样地调查法对样地内乔木层、灌木层和草本层的生物量进行取样与调查，结果表明乔木层生物量为标准木52.36 kg/株、优势木118.33 kg/株、被压木8.55 kg/株，灌木生物量为7.257 7×103 kg/hm2，草本生物量5.49 kg/hm 2。林下灌木及草本植物生物量对整个林分生态效益具有一定程度影响，因此，在经营过程中应改善林分结构，使林分发挥最大生态效益。</br>Larix principis？？rupprechtii (larch) is a major composition tree of alpine coniferous plantation in the northeast, north, southwest of China. The biomass of larch plantation plays an important role in enhancing the economic and ecologic value of plantation. We sampled and investigated the biomass of the tree layer, shrub layer and herb layer by the method of fixed sample plot survey. The results indicated that the biomass of the standard wood of the tree layer was 52.36 kg/strains, which of the dominant tree was 118.33 kg/strains, of the oppressed wood was 8.55 kg/strains, of the shrub was 7.257 7×103 kg/hm2, and of the herb was 5.49 kg/hm2.The structure of the plantation should be improved to release more economic benefit of the larch plantation
