摘　　要：研究了具有无穷时滞具有m个捕食者和n个食饵的的Lotka-Volterra非自治系统,主要利用比较定理得到了系统内生物种群持续生存的充分条件.In this paper, a class of m-predators and n-preys nonautonomous Lotka-volterra system with infinite delays is studied. The conditions guarantee the persistence of the system are obtained, by the use of comparison theorem mainly.
