Chaos and Control in a Prey-predator System with Periodical Harvesting and Stage Structure

摘要：

With the purpose of investigating the dynamics of prey-predator system with stage structure and periodical harvesting, a stage-structured prey-predator model with periodical harvesting is established.By virtue of the Poincar ′e surface-of-section technique and computation of Lyapunov exponents,chaotic behavior and quasiperiodic behavior in the proposed model are stud-ied.Furthermore,chaotic behavior in the model system is controlled by constructing a special form of a continuous perturbation. Numerical simulations are carried out to show the consistency with theoretical analysis.
