Abstract: The paper discusses stability concepts and methods of stability investigation in models describing the climate-biosphere interaction for a hypothetical zero-dimensional model. The climate-biosphere model proposed by Svirezhev-& von Bloh, 1997, exhibited interesting features concerning the stability and sensitivity to perturbations of the global system. The work is focused on the determination of transition times between the equilibriums due to random perturbations. In investigate bifurcations in the model to describe complex behavior in the model with multiple equilibriums. Global vegetation pattern dynamics strongly depends on production and hence evolutionary models must explicitly use this concept. We have shown analytically that GVP dynamics could demonstrate complex behavior with multiple equilibria, chaotic dynamics associated with them as well as transition zones between consequent states.
