摘要: 森林自疏理论的研究已经有了很大发展,然而到目前为止很少有人去研究林木自疏过程中的密度变化规律。根据“3/2自疏法则”和植物种群生物量增长模式,我们提出了森林自疏过程中种群密度变化规律的模型。

Abstract: According to "-3/2 self-thinning rule" and the model of biomass growth of plant population,the authors offer a mathematical model of forest population density change during population undergoing selfthinning:where r,β,k are positive constant,N represents forest density.
