对直径生长转移概率矩阵模型进行了线性扩展,用以研究混交异龄林的树种组成问题。以扩展后的矩阵模型为基础建立了考虑树种组成的最优经营模型,并以吉林省东部长白山林区针阔混交异龄林为对象,对模型进行了求解。结果显示作者所建立的模型同原模型一样具有直观性强、易于理解和应用的优点;特别是该模型在不增加问题复杂性的情况下,考虑了长期以来不易于定量化的最优树种组成问题。所得到的经营方案可供该地区制定经营决策时参考。
The linear expansion of the diameter growth transfer probability matrix model was used to study the tree species composition of heterogeneous mixed forest. Based on the expanded matrix model, an optimal management model considering the composition of tree species was established. The model was solved for the mixed stands of coniferous and broadleaf trees in Changbai Mountain of eastern Jilin Province. The results show that the model established by the author has the advantages of intuitiveness, easy to understand and apply as the original model. Especially, the model does not increase the complexity of the problem and takes into account the composition of the optimal tree species, which is not easy to quantify for a long time problem. The operating plan is available for reference in the development of business decisions in the region.
