摘　　要：考虑一类具有阶段结构和Holling-TannerⅡ类功能反应的Leslie周期系统,利用重合度理论得到该系统正周期解存在的充分条件.In this paper, a class of nonautonomous stage structure Leslie system with Holling-tanner type Ⅱ functional response is investigated. By using continuation theorem of coincidence degree theory, sufflcient conditions are obtained for the extistence of positive periodic solution.

关 键 词：正周期解 重合度 阶段结构 Leslie系统
