摘要：
Complex branching and irregular foliage distribution render the quantitative description of tree crowns a scientific and technological challenge. This study explores the use of fractal geometry to describe crowns. Based on the derivation of a classical model-the Sierpinski tetrahedron-a new method we call comprehensive structural relationships (CSR) is described for estimating fractal dimensions in 3-D space. All possible structural relationships were examined under the scale transformation and space expansion modes, resulting in 15 structural relationships. The method was applied to a deciduous species to describe structural characteristics of branching and foliage distribution. Results demonstrate that it is practical to estimate fractal dimensions of tree crowns in the field. © 2014 - Canadian Institute of Forestry.
