本文展示了如何使用 SilviScan-3 数据来绘制木材属性的树内分布，并计算可用于树与树比较的相关统计数据。为此开发了一种名为 EvaluTreeMap 的算法，该算法基于将树干细分为三角形元素。它使用具有圆锥对称特性的圆锥形茎进行了验证。为了说明该程序的一些应用，它被用于初步评估蜜环菌根病对花旗松树纤维粗度的影响。关键词: SilviScan-3, 纤维特性, 树内变化, EvaluTreeMap, 网格划分, 映射, 茎体积, 树的平均特性和标准差, 奥氏蜜环菌, 纤维粗度, 花旗松
This paper shows how SilviScan-3 data can be used to map the within-tree distributions of wood properties, and to compute relevant statistics useful for tree-to-tree comparisons. An algorithm named EvaluTreeMap was developed for this purpose, based on subdividing the stem into triangular elements. It was validated using a stem of conical shape with properties exhibiting conical symmetry. To illustrate some applications of the program, it was used for the preliminary evaluation of the impact of Armillaria root disease on the fibre coarseness of Douglas-fir trees. Key words: SilviScan-3, fibre properties, within-tree variations, EvaluTreeMap, meshing, mapping, stem volume, tree's mean properties and standard deviation, Armillaria ostoyae, fibre coarseness, Douglas-fir
