Quantitative Estimation of Tree Branches and Analysis of Plane Distributional Structure of Park Trees

Abstract

This paper describes the quantitative estimation of tree branches and the analysis of plane distributional structure of the park trees. Following results were obtained.
1. By use of stream order that is used for the quantitative analysis of rivers, we observed the linear relations between branch order and numbers, length or diameter of branches on semilog or log-log graphs. With these regressions, we could estimate the quantity of branches only from diameter at the clear height of the tree.
2. By use of the division of the park area, with triangular elements that have three neighboring trees as the vertexes, we could obtain the stand branch densities at each element and the plane distribution of them. We think them applicable to the structural analysis of the park tree distribution.
