摘要/Abstract

摘要： 以矩阵模型为基础,利用林分直径生长、进界生长和枯损的资料,用非线性动态模型模拟长白山阔叶红松林动态生长,并预测短期内在不同的采伐强度下林分的径阶变化,分析不同采伐强度对年生长量、年收获量和恢复年数的影响。结果表明,非线性动态模型在模拟林分生长上具有结构严谨和精度高的优点。将模型推广到采伐林分中,为科学地经营阔叶红松林,制定合理的采伐方案提供科学依据。

Abstract: The objective of this study was to present a matrix model of uneven-aged broadleaved and Korean pine mixed forest in Changbai Mountain,based on equations of ingrowth,upgrowth and mortality model.Predictions were tested against post-sample observations for short-term accuracy.This growth model was then applied to study dynamic varivation of diameter grade,and effects on different cutting intensity to periodic average increment,annual yield and refaunation time were also analysed.The validity of the model was tested,which can provide the basic data for forest management policy makers.
