摘　　要：研究基于Volterra捕食模型的非线性系统,利用MATLAB软件,用理论分析结合数值模拟的方法描述周期解的性质和相图形貌,讨论系统的稳定性及其应用。结果表明,MATLAB软件能很好的应用于捕食模型的建立,并且得到一些渔业生产和农业害虫防治的理论,以指导现实生产。The nonlinear systems based on the Mode of Volterra predation are studied in this paper.The properties of periodic solutions and phase diagrams are described with theoretical analysis and numerical simulation by matlab.And the stability and applications of the systems are discussed.The results show that,matlab software can well applied to the model of predation.And theory of fisheries and agricultural production pest controlling can be obtained,and used to guide the production.
