Simuler des peuplements de structures variées pour faciliter l'utilisation des modèles "arbre" spatialisés

Abstract : In order to study mixed or uneven forest stands, foresters have modelled the dynamics of each individual tree as a function of its characteristics and local neighbourhood. These spatially-explicit individual-based models can be difficult to use, because the characteristics and location of each tree in the initial state have to be specified before running a simulation. Modellers have therefore developed specific tools to simulate such spatially-explicit initial state. The aim of this paper is to detail this concept of spatially-explicit initial state simulation, and to illustrate how such tools can facilitate the use of individual-tree growth models. We first present two applications, one on a regular stand, and another one on a mixed uneven stand. Then we propose a formalisation of these tools, and discuss their advantages and drawbacks.
