摘　　要：本文研究了一类具有多时滞脉冲单种群模型.利用迭合度连续性定理,讨论了系统正周期解的存在性.此外,并应用实例和数据模拟来验证分析了主要结论.In this paper, we investigate a single-species system with multi-time delays. By using the co- incidence degree theory, the positive periodic solution of system is discussed. In addition, the practical application and numerical analysis are also used to illustrate the result.
