摘　　要：以黔东南杉木林生物量为研究对象,采用随机设样及建立相对生长模型的方法对黔东南杉木林单木生物量、乔木层生物量及林分下层生物量进行了研究。结果表明:杉木林的生物量为305.82 t/hm2,地上部分生物量为267.55 t/hm2,地下部分生物量为38.27 t/hm2。其中树干生物量为167.53 t/hm2,树皮生物量29.38 t/hm2,树枝生物量46.13 t/hm2,树叶生物量24.51 t/hm2,根系生物量38.27 t/hm2,各器官生物量分配比例的大小顺序为:树干﹥树枝﹥根系﹥树皮﹥树叶。乔木层生物量为305.82 t/hm2,占林分生物量的98.14%;灌木层生物量为1.09 t/hm2,占林分生物量的0.35%;草本层生物量为1.19 t/hm2,占林分生物量的0.38%;枯落物层生物量为3.51 t/hm2,占林分生物量的1.13%。To research biomass and its allocation of Chinese fir forests in Southeast of Guizhou, and evaluate ecosystem of Chinese fir forests, two methods of random sample and relative growth model were used to estimate biomass of Chinese fir single tree, arbor layer and undergrowth layer of stands. The results indicated that biomass of Chinese fir forests was 305.82 t/hm2, overground biomass was 267.55 t/hm2, and underground biomass was 38.27 t/hm2. Biomass of stem, branch, root, bark and leaf was respectively 167.53, 46.13, 38.27, 29.38 and 24.51 t/hm2. Biomass of Chinese fir organs varied as follows： stem〉branch〉root〉 bark〉leaf. Biomass of arbor layer was 305.82t/hm and accounted 98.14%; biomass of shrub layer was 1.09 t/hm2 and accounted 0.35%; biomass of herb layer was 1.19t/hm and accounted 0.38%; biomass of litter layer was 3.51 t/hm2 and accounted 1.13%.
