树木根系生物量的估算对于了解森林系统和树木生长的动态具有重要意义。在估计树桩下生物量时，木质根的提取困难且耗时，这往往是一个限制因素。从其他研究中推导出的根系生物量与胸径的回归方程在林业应用中可能是有用的，并可作为生长模型的简单输入变量。数据开发回归方程，并在可能的情况下，方程取自最近的文献云杉，花旗松，樟子松，辐射松，火炬松，山毛榉，冬青栎和栎。用欧洲研究项目的数据建立了石油栎的方程。
Estimates of tree root system biomass are important to understanding the dynamics of forest systems and tree growth. The difficult and time-consuming extraction of woody roots is often a limiting factor when estimating the below-stump biomass. Regression equations of root system biomass on diameter at breast height derived from other studies might be useful for applications in forestry and as a simple input variable for growth models. Data for developing regression equations and, where possible, equations were taken from the recent literature for Picea abies, Pseudotsuga menziesii, Pinus sylvestris, Pinus radiata, Pinus taeda, Fagus sylvatica, Quercus ilex and Quercus douglasii. The equation for Quercus petraea was developed using data from European research projects.
