本研究以豫西山区日本落叶松人工同龄纯林为研究材料，模拟了优势水平均高随立地因子变化的混合型数量化回归模型；按５个地位级模拟了平均标准木、优势木的树高、胸径、蓄积生长的理查德曲线、修正指数曲线模型；按５个地位级模拟了每ｈｍ２蓄积生长的罗辑斯蒂克曲线模型及每ｈｍ２立木株数随树龄递减的双曲线模型。该研究共模拟林分及单株林木生长的数学模型４１个，较系统地描述了日本落叶松人工林主要生长指标与诸立地因子的定量关系以及随树龄变化的动态定量关系，为日本落叶松人工林的计算机管理、林地生产力预估奠定了数学基础，提供了科学依据。
In this study, the artificial forests of Larch (Larix kaempferi) in the mountainous area of western Henan were used as the research materials to simulate the mixed quantitative regression model that the average level of dominant species varied with the site factors. The average standard tree and dominant tree Height, diameter at breast height, accumulated growth and modified exponential curve model. According to five status levels, the model of logistic curve per hm2 accumulation and the hyperbolic model with decreasing number of standing trees per hm2 were studied. In this study, 41 mathematical models of stand and individual tree growth were simulated. The quantitative relationship between main growth index of Larix kaempferi plantation and site-setting factors and the dynamic quantitative relationship with age were described systematically. Plantation computer management, forestry productivity estimates laid the mathematical foundation, provides a scientific basis.
