We excavated 121 root systems of various species (78) and sizes (up to 116 cm in dbh), and estimated both above- and below-ground biomass in a lowland primary dipterocarp forest in the Pasoh Forest Reserve, Peninsular Malaysia. Total below-ground (BGB) and above-ground biomass (AGB) was estimated to be 95.9 and 536 Mg ha-1, respectively. The biomass-partitioning ratio (BGB/AGB) was about 0.18. The dbh-based allometric equation developed in this study, might be useful for evaluating below-ground carbon stocks in other stands of similar forest (old-growth dipterocarp) in South-East Asia.

我们挖掘了121根系统的不同物种（78）和大小（高达116厘米的DBH），并估计地上和地下生物量在一个低地主要龙脑香林的Pasoh森林保护区，马来西亚半岛。地下生物量和地上生物量估计分别为95.9和536兆毫克公顷。生物量分配比（BGB/AGB）约为0.18。基于胸径的异速生长方程在这项研究中，可能是有用的，在东南亚类似的森林（古老的龙脑香）的其他林分地下碳储量的评估。
