摘要 本文利用半连续动力系统构建一类带有气象因素影响和状态反馈脉冲控制的蚜虫生物治理模型.首先研究无控制系统和控制系统的动力学性质,包括平衡点及周期解的存在性、唯一性和稳定性,以及系统的吸引域.然后运用数值模拟的方法,一方面验证理论结果的正确性,另一方面分析温度、湿度以及天敌释放量对两类种群发展以及蚜虫生物防治效果的影响. In this paper,a kind of aphid biological control model with meteorological factors and state feedback impulsive control is constructed by using semi-continuous dynamic system.Firstly,the dynamic properties of the uncontrolled system and the control system are studied,including the existence,uniqueness and stability of equilibrium points and periodic solutions,as well as the region of attraction of the systems.Then,using the method of numerical simulation,on the one hand,the correctness of the theoretical results is verified,on the other hand,the effects of temperature,humidity and the release of natural enemies on the development of two kinds of populations and the biological control effect of aphids are analyzed.
