Transition matrix modelling on disturbance-controlled persistence of plant population

We consider the disturbance-controlled persistence of plant population with a transition matrix modelling, and discuss the contribution of ecological disturbance to the population persistence. The considered population is assumed to be the species subordinate about the competition for its persistence, so that it goes extinct in the environment without ecological disturbance. Our mathematical results indicates such a possibility that the ecological disturbance with an appropriate period assures the persistence of such species of plant.
