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 coniferous and broad-leaved mixed forest in Beigou Forest Farm of Mulan Forest Management Bureau as the research object, the species of Betula platyphylla in the standard field were studied in detail. The biomass of the birch was determined by the stratified method and the growth model was established and the forest stand The results showed that: 1) The power function is the optimal model for the biomass of Betula platyphylla. 2) Optimum model of Betula platyphylla The total biomass of Betula platyphylla was 43 921.27 kg / hm2 and 21 433.58 kg / hm2, accounting for 49.72% (trunk), 21.04% of total carbon storage, (Tree branches), 6.14% (leaves) and 23.10% (tree roots). The distribution of carbon storage in the stands was dry> roots> branches> leaves.
