研究一类具有两类脉冲扰动与Holling-Ⅱ功能性反应的捕食-食饵模型,利用比较原理得到系统成年食饵灭绝周期解全局吸引与系统持续生存的充分条件,并用数值模拟验证所得理论结果的可靠性.%A class of predator-prey model with two impulsive perturbations and Holling- Ⅱ functional response was investigated. Using comparison theorem, the sufficient conditions for global attractiveness of the mature prey-eradication periodic solution and permanence of the system were obtained. It was Verified by numerical simulations that the theoretical result obtained was reliable.
