摘要
根据黑龙江省孟家岗林场、江山娇林场的固定标准地及吉林省松江河地区的团状枝解析样地调查数据，基于Ｋｏｒｆ生长方程，导出了落叶松人工林分自然稀疏模型和断面积生长模型，以此为核心构造了满足相容性原则的树高曲线动态预估模型、林分收获预估模型落叶松人工林生长模型系统。用由这４个模型构成的模型系统可模拟不同林分的平均胸径、每公顷株数、林分断面积及林分蓄积的生长过程，并与实际林分很接近。
Based on the data of permanent plots in Mengjiangang Forest Farm,Jingshanjiao Forest Farm of Heilongjiang Province and of some circular branchanalysis plots in Songjianghe area of Jilin Province,the selfthinning model and basal area growth model were derived for larch plantation.The whole stand model system,set up in this research,was composed of 4 compatible models, i.e.the selfthinning model,prediction model of heightdiameter curve,stand basal area growth model,Schumacher′s stand yield model.Using the model system,quadratic mean diameter,mean height,the number of surviving trees per hectare,stand basal area,and stand volume can be evaluated for various levels of initial density and different sites.
