| 摘 要： | 收集朝阳县主要造林树种油松、刺槐和华北落叶松的解析木数据,按照不同立地类型对数据进行分类整理,运用6种高生长模型对树高生长进行拟合和研究.结果表明,大部分树种高生长用Logistic模型最佳,油松在阴坡厚土层和阳坡厚土层的高生长用Richards方程最佳.相对生长方程在刺槐阳坡中土层和阳坡厚土层的高生长模拟也取得了满意的结果.

| Abstract: | Stem-analysis data of such major afforestation tress species as Pinus tabulaeformis,Robinia pseucdoacacia and Larix principis-rupprechtii in Chaoyang county were collected and classified in terms of site types,growth of height was simulated and studied by using 6 growth models of height.The results showed that: Logistic equation was optimum for most tree species,and Richards equation was best equation for growth of height of Pinus tabulaeformis in both shady and sunny slopes with thick soil layers.Satisfied effects were obtained by simulating growth of height with relative growth equation for Robinia pseucdoacacia in sunny slopes with medium-thick and thick soil layers. |
