摘　　要：以木兰林管局北沟林场内的典型的针阔混交-人工林的山杨为对象,经过5a对标准地山杨等树种进行了调查研究,利用分层切割法对山杨生物量等进行测定。结果表明：1）混交林中山杨单株总生物量的变化范围是4.10~344.16kg,其生物量各器官分配百分比为：干均值为63.03%（53.21%~69.14%）,枝均值为11.40%（5.26%~18.12%）,根均值为20.12%（16.69%~22.67%）,叶均值为5.44%（3.42%~8.46%）。2）山杨树高、胸径与各器官生物量有较高的相关性,建立的山杨生物量最优模型为：W干=111.985 D1.702;W枝=119.21（D2 H）0.578;W根=1/（0.000012 1＋0.001 91×0.77D）;W叶=1/（0.000 033 3＋0.003 69×0.815D）;W全=1/（0.000 002 5＋0.000 003 7×0.771D）。3）山杨生物量的最优模型推算林分中山杨的总生物量为33 632.98kg·hm-2,碳储量为13 808.77kg·hm-2,各器官分别占总碳储量的60.06%（树干）、15.40%（树枝）、5.31%（树叶）、19.24%（树根）。林分碳储量分配情况为干〉根〉枝〉叶。Taking Populus davidianain typical theropencedrymion-plantation in Beigou Forest Farm of Mulan Forest Bureau as object,A 5-year-long investigation was carried out on the biomass and carbon storage by using the methods of stratified cutting and establishing the growth model to calculate the biomass and carbon storage.The results showed that：1）ranges of variation of total biomass of the individual plant were 4.10to 344.16kg,the biomass distribution percentages of individual organ were trunk：63.03%（53.21%-69.14%）,branch：11.40%（5.26%-18.12%）,root：20.12%（16.69%-22.67%）,leaf： 5.44%（3.42%-8.46%）.2）Height and DBH of P.davidianaexhibited higher correlation with organ biomass,and the established optimal models were WT =111.985D1.702;WB =119.21（D2 H）0.578;WR =1/（0.000 012 1＋0.001 91×0.77D）;WL =1/（0.000 033 3＋0.003 69-3×0.815D）;WF =1/（0.000 002 5＋0.000 372×0.771D）.3）According to the optimal model,the total biomass was 33 632.98kg·hm-2 in stand,carbon storage was 13 808.77kg·hm-2.The percentages of each organ were 60.06%（trunk）, 15.40%（branch）,5.31%（leaf）,19.24 %（root）.Carbon storage distribution was in the order of stem rootbranchleaf.
