4.Description##plugins.generic.mcfnsReadingTools.abstract##Most models of forest communities cannot represent the asymmetry of crowns resulting from inter-tree competition. However, such a representation is important for the accurate simulation of mixed and uneven-aged forest stands. In the paper we propose a new model of a forest stand, which is individual-based and spatially-explicit, i.e., taking into account the relative positions and properties of all competing trees within a plot. The model uses species-specic coecients to take into account the dierent strategies of competition for light. The model operates with the 3D-representation of tree crowns and light transmission through the canopy using discrete spatial and temporal resolution. It is thus capable to represent the asymmetry of crown shapes and biomass distribution being a response of tree geometry to the local surrounding of the given tree. In order to estimate the performance of the model in the simulation of aboveground competition, a set of simulation scenarios, representing stands of dierent spatial structures, ages, and species compositions, were used. Simulations showed a positive eect of species mixture on crown size and light interception eciency, as well as speciesand age-related dependencies of these parameters. Dierences in the spatial structure mostly aected the light transmission pattern at the stand level. The importance of crown asymmetry in the increase of light interception eciency was also shown. Thus, the proposed model allows to simulate light absorption by the canopy with a high spatial resolution, using relatively few parameters. The model imitates a mechanism allowing trees to decrease the aboveground competition in forest stands, and it is also applicable for simulating aboveground competition in mixed uneven-aged stands.
