马尾松种群生物量及其密度效应研究

Studies on Biomass and Density Effect in the Pinus Massoniana lamb

摘要:

马尾松种群生物量及密度效应研究结果显示，马尾松生物理随生长阶段不同，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。

Abstract:

The population biomass and density effect of Pinus massoniana Lamb were studied. Results showed that the Pinus massoniana Lamb biomass distribution propertion in every part with different growth stage,but the biomass main concentrate in trunk .and the biomass is Logistic decrease with the density increase.
