| Outline of Final Research Achievements |
We developed statistical models to estimate mortalities of tree branches, growth rates of trunk and foliage depending of three dimensional light distribution in forest. The light distribution was reconstructed based on an open data, Inabu experimental forest of Nagoya University. Reconstructed forest using OpenGL library allowed us to know the relationship between forest structure and light resource distribution. We also developed a time-series data of tree ring to know the relationship between the external environment and the radial growth of trees.
