摘要
本文提出同龄纯林自(然)稀硫的理论方程式。这个方程式概括了各种不同立木度林分的自稀疏规律,由此方程式结合断面积生长模型可以导出不同初始密度林分的自然生长过程。熟知的完满立木度林分的自稀疏规律是本文所述方程式的特例。一个实例说明不同初始密度林分自然生长过程的计算方法及例证不同密度林分自稀疏规律的不同。
A theoretical equation discribing the self-thinning laws for even-aged pure stands is derived. The equation summarizes self-thinning laws forvarious stocking stands. A series of growth tables of unthinned even-agedstands in relation to initial densities can be obtained by using both of theself-thinning equation and a basal area growth model. The well-knownself-thinning law for fullstocking stand is a special case of the equation asshown in this paper. An example illustrates an algorithm of stand growthtables and confirms the relationship between the self-thinning rate and thestand density.
