摘要:
树木干曲线具有分形的结构，文章应用分形方法对甘肃小陇山地区86棵不同树种的单木以及解析木干曲线进行研究，通过计算得到干曲线的分形维数介于2～3之间，研究结果表明同一树种树木干曲线的生长趋势是一致的。经过对单木干曲线和标准解析木干曲线分形维数的测定以及比较分析，可以发现同一树种不同径阶的树木干曲线具有统计意义上的自仿射分形特征，表明分形方法在对树木及其组成部分的形态上的描述作用极大。文章针对立木的测量，采用三维激光扫描成像系统，不仅获得了丰富的测树因子信息，更以此为基础对森林计测学研究进行了扩展。
Abstract:
The stem curve of trees has fractal configuration,the main work of this text is study the stem curve of signal tree and parse tree of 86 different kinds on Xiaolongshan in Gansu province with methods of fractal.From the calculation we can see that the fractal dimension of stem curve is between 2 and 3,which show that the vegetal trend of stem curve of the same kind is coincident.According to the determining and comparative analyse of stem curve between simple trees and standard parse trees,we can see that the stem curve of same kind but different diameters is provided with self-affine characteristic in the statistical meanings,and indicate that fractal methods play an important role in describing the configuration of trees and the compositive parts.This research aims at the surveying of stumpage by 3-D laser scanning imaging system which is not only obtain abundant information of surveying tree gene,but also expend the research of forest calculating and surveying which is a very significative work.
