Un modèle énergétique pour la dynamique de la végétation

Abstract We try here to model the vegetal dynamics, so progressive as regressive one, by using concepts stemming from the classic physics and we try to compare some results obtained in the empirical observations, specially the fact that the speed of the evolution in a series decreases when one get closer to the climax. At the same time, we discuss the concepts of bryoclimax, homothety, specialized vegetations, philosophy of trop, sylvigenetic maturation, complexity. We also illustrate the progressive dynamics by means of some spectral series (biological, systematic, architectural, or seeds scattering and adaptative strategy).
