【Abstract】 A stochastic Beddington-DeAngelis functional response prey-predator system with impulsive perturbations is proposed and investigated.By the Itd formula and comparison theorem of stochastic equations,we proof that our system has a unique positive solution, the conditions for extinction of system and the boundedness of the system’s solution.更多还原
