A numerical simulation model is presented to describe primary production and species transition of stream periphyton communities, in which the net growth rate of periphyton biomass is estimated by the balance of primary production, immigration, respiration and detachment of the periphyton biofilm. The interspecific competition of filamentous periphyton and non-filamentous periphyton is included in the model via the differences of the algal densities and the immigration patterns to the substrate. The solar radiation inside the periphyton biofilm is estimated by the Lambert-Beer's equation, and the nutrient distribution inside the biofilm is calculated from the diffusion equations of nutrients. The physiological parameters used in the present computations are evaluate from the labatory data on periphyton growth. The results of the computation show that the model can predict the temporal variation of periphyton biomass and the species transition from the non-filamentous periphyton to filamentous periphyton well.
