摘　　要：分别采用维量分析法和＂全体收获法＂,对克拉玛依人工杨树林乔木层生物量及地下植被层和地上凋落物层生物量进行分析。结果表明：1乔木层各器官生物量分配排序为：树干（60.79%）〉树根（14.27%）〉树枝（9.84%）〉树皮（8.96%）〉树叶（6.14%）;2径级在6~12 cm的乔木生物量占到61.78%;3单沟单植8 m×0.75 m和单沟单植4.5 m×2 m造林模式是该区域的较好选择;4在相同种植模式下,人工林内新疆杨比俄罗斯杨更具有优势;5乔木层、林下植被层和凋落物层的平均生物量分别为45.285 t·hm^-2、1.753 t·hm^-2和4.171 t·hm^-2。Using dimensional analysis and all harvesting method,this study measured and analyzed the biomasses of the arbor layer,the understory vegetation layer and the litter layer in the poplar plantations in Karamay. The results showed that the tree organ biomasses of the arbor layer decreased as an order of trunk（ 60. 79%） root（ 14. 27%） branch（ 9. 84%） bark（ 8. 96%） leave（ 6. 14%）. The biomass of the arbor vegetation with 6-12 cm diameter breast height（ DBH） accounted for 61. 78% of the arbor vegetation biomass. It was a better choice to adopt 8 m × 0. 75 m and 4. 5 m × 2 m single groove single plant models in this area. Populus alba var. pyramidalis was more suitable than than Populus russkii under the same tree-planting patterns in the poplar plantations. The mean biomasses of the arbor layer,the understory vegetation layer and the litter layer were 45. 285 t · hm^- 2,1. 753 t·hm^- 2and 4. 171 t·hm^- 2,respectively. The research provided theoretical and practical guidance for the implementation of the large-scale poplar plantations in desert environment.
