摘要
以矩阵模型作基础,利用进界生长、径阶向上生长和枯损量的材料,拟合了异龄林动态系统模型,并建立了最优控制模型。以新疆天山云杉异龄林为研究对象,分析现实异龄林的生长动态并对最优调整策略进行探讨,有关结果可作为生产的依据。
In this paper the models of uneven-aged forest dynamic system and optimal control system are discussed. On the basis of matrix model and the data of Ingrowth,Upgrowth and Mortality, the model of uneven-aged forest dynamic system and the model of optimal control system have been established. Taking the schren sprua (Picea schrenkiana var. tianshanica) in Xinjiang as a research object, the growth dynamics of an actual uneven-aged forest is analysised and the optimal conversion regimes are approached. Some results obtained can be used in production management.
