马尾松种群生物量及密度效应研究结果显示，马尾松生物量随生长阶段不同，各组分分配比例存在差异，但主要集中在干材部位。随种群密度增加，生物量呈逻辑斯蒂曲线递减。
Masson and Pinus massoniana population biomass and density effects of the results showed that the biomass of Pinus massoniana different stages of growth, the proportion of each component distribution differences, but mainly concentrated in the dry material parts. With the increase of population density, biomass decreased in a logistic curve.
