在印度尼西亚东加里曼丹省塞布卢的一片以龙脑香科为主的高大原始热带低地常绿雨林中，对地上植物生物量进行了检查，特别关注森林生长周期的间隙期、建设期和成熟期。根据分层修剪技术检查的样本树木的尺寸记录和研究样地树木的胸径库存数据，通过异速生长相关法估算较大树木（胸径≥4.5 cm）的生物量。较小植物（DBH < 4.5 cm）的生物量是通过在小样方地块中收获植物来估算的。尽管不同生长阶段不同斑块的地上生物量估算值存在较大差异，但1.0 ha小区的地上生物量为509 t/ha，单侧LAI为7.3 ha/ha。这些值似乎是由于高大的森林结构、巨大的挺水树木（超过 70 m 高）和适度的植物体堆积所致，胸径≥4.5 cm 的树木的断面积值为 38.8 m2/ha。
Aboveground plant biomass was examined in a tall virgin tropical lowland evergreen rain forest dominated by Dipterocarpaceae in Sebulu, East Kalimantan, Indonesia, with special reference to the gap-, building- and mature phases of the forest growth cycle. From the records of dimensions of sample trees examined by the stratified clip technique and DBH inventory data of trees in a study plot, the biomass of larger trees (DBH ≥4.5 cm) was estimated by the allometric correlation method. The biomass of smaller plants (DBH < 4.5 cm) was estimated by harvesting the plants in small quadrat plots. Although large differences were found between aboveground-biomass-estimates in different patches of different growth stages, the aboveground biomass in a 1.0 ha plot was 509 t/ha, and the one-sided LAI was 7.3 ha/ha. These values seem to result from the tall forest architecture with huge emergent trees (over 70 m high) and a moderate packing of plant mass indicated by the basal area value of 38.8 m2/ha for trees with DBH ≥4.5 cm.
