摘　　要：讨论了在具有常数避难所情况下的带阶段结构的捕食和食饵种群的持久性.食饵的种群大小比避难所可容纳的种群小,食饵种群都躲在避难所中;食饵的种群大小比避难所可容纳的种群大,一部分的食饵被捕食.得到了在这两种情况下种群都可持久发展的条件.This paper has studied the permanence of a stage-structured predator-prey system with constant refuge（ stage structure for both predator and prey）. While the size of prey population is smaller than that of the refuge,the prey population all hide in refuge,otherwise they are partially preyed by predator. Therefore,predator-prey system has obtained the conditions for sustained development in both cases.

关 键 词：常数避难所 阶段结构 持久性
