摘　　要：以木兰林管局北沟林场内的针阔混交林为对象研究,对标准地白桦等树种进行了详细的调查研究,利用分层法对白桦生物量等进行测定,建立生长模型并推算林分中白桦生物量和碳储量,结果表明:1)幂函数为白桦生物量最优模型。2)白桦生物量的最优模型推算林分中白桦的总生物量为43 921.27 kg/hm2,碳储量为21 433.58 kg/hm2,各器官分别占总碳储量的49.72%(树干)、21.04%(树枝)、6.14%(树叶)、23.10%(树根);林分碳储量分配情况为干>根>枝>叶。Taking the mixed coniferous and broadleaf forest of Beigou forest farm in Mulan Forestry Bureau as a research object,we carried out a detailed investigation of Betula platyphylla.The biomass of Betula platyphylla was measured by using stratified method for establishing the growth model and calculating the Betula platyphylla biomass and carbon storage in forest. The result shows that （1 ）Power function is the op-timal model of Betula platyphylla biomass.（2）According to the optimal model of Betula platyphylla biomass the total biomass of Betula platyphylla is 43 921.27 kg/ha in stand and carbon storage is 21 433.58 kg/ha. The carbon storage of each organ is respectively 49.72%（trunk ）,21.04%（Branch ）,6.14%（leaf）, 23.10%（root）of the total carbon reserves ratio.Carbon storage distribution is stem〉root〉branch〉leaf in the stand.
