  1. Classification of the models

  2. At genesis of forest modelling the three Wisemenhave operated : The first has been called BIOLOGIST and searched for answer to: „Why tree organs growth?“ He gave to world: algorithm of photosynthesis Gift has been accepted in disciplines: bioclimatology, ecopedology, plant physiology Process-based models have been established. The second has been called MATHEMATICIAN and searched for answer to: „How the tree is formed in space ?“ He gave to world: fractal Gift has been accepted in disciplines : formal grammar, fractal geometry, computer graphics Structural models have been established. The third has been called FORESTER and searched for answer to: „What benefit is produced by forest?“ He gave to world: regression equation Gift has been accepted in disciplines : biometry, forest mensuration, forest yield science Empirical models have been established. 1 2 3 2 1 3 1
