利用最近对不同热带森林类型的面积及其相应的林分体积的评估来计算热带森林的生物量密度和总生物量。总生物量估计为20.5倍。未受干扰的阔叶林和开放阔叶林的加权生物量密度分别为176和61 t /ha。这些值比以前报道的要低得多，这引起了人们对陆地生物群在全球碳收支中的作用的质疑。
Recent assessments of areas of different tropical forest types and their corresponding stand volumes were used to calculate the biomass densities and total biomass of tropical forests. Total biomass was estimated at 205 .times. 109 tons, and weighted biomass densities for undisturbed closed and open broadleaf forests were 176 and 61 tons/ha, respectively. These values are considerably lower than those previously reported and raise questions about the role of the terrestrial biota in the global carbon budget.
