摘要
本文讨论林分表法预估林分生长的核心,以单木模型计算树木生长量、转移概率和未来直径分布。结合其它一些林分调查因子的生长方程编制,模拟兴安落叶松(Larix gmenilii)天然林的生长程序(UIMN BAS)。该程序可模拟林分在自然状态和间伐后的生长过程,为定量间伐提供选择依据。
The issue of predicting growth was discussed. Tree diameter increment, transition probability and future diameter distribution were calculated based on individual tree growth model. Combined with growth equation of other stand factor, computer programme of UIMN BAS for stimulating growth of natural larch stand was constructed. It can simulate stand growth both in natural state and after thinning, and provide basic data for quantitive thinning.
