中文摘要：

研究了具有HollingⅣ型功能性反应的非自治三种群食物链模型,利用重合度理论中的延拓定理在周期的情况下获得了系统正周期解存在的充分条件.

英文摘要：

A non-autonomous three-species food-chain model with the Holling Ⅳ functional response is proposed in this paper.The condition for existence of a periodic solution for periodic case is obtained by using the continuation theorem of coincidence degree.
