摘要：A single species stage structure system with pos-itive feedback control is proposed and studied in this paper.Local and global stability property of the boundary equilibriumand the positive equilibrium are investigated, respectively. If thesystem without feedback control is extinct, then we show that bychoosing suitable control variables, extinct species can becomeglobally stable, or still keep the property of extinction. If thesystem without feedback control is global stability, then to en-sure the system admits a globally stable positive equilibrium, weshould also restrict the feedback control variable to the suitableinterval. An example together with its numeric simulations ispresented to verify the main results.
