摘要
<jats:p>Power function model and linear function model were commonly used to express the relationships between stand volume and biomass. However, the relative accuracy is still unclear. In order to compare the accuracy of the two types of model, field measurement data of 279 pine forest stands in China were collected from published literatures. Using the data collected, the relationships between stand volume and aboveground biomass (AGB) of <jats:italic>Pinus koraiensis</jats:italic> forest, <jats:italic>Pinus armandii</jats:italic> forest, <jats:italic>Pinus massoniana</jats:italic> forest, <jats:italic>Pinus tabulaeformis</jats:italic> forest and <jats:italic>Pinus</jats:italic> forest were established. The mean relative error and mean absolute values of relative errors were employed to test the errors of the established equations. The goodness-of-fit and errors of these two types of model were compared. The results show that the power function models could generally express the relationships better than the linear function models. Also, the errors of the power function models are generally lower than those of the linear function models.</jats:p>
