摘要
在生态系统中,种群的稳定性一直是研究的重点内容之一,考虑了一个同时具有时滞和功能性反应的n种群模型,其中一个为被捕食者,其它的为捕食种群,通过微分不等式和构造合适的Lyapunov泛函给出了解的有界性和正平衡点全局稳定的充分条件,并给出模型的数值模拟结果。
others-studied. stability One of the predator) ratio By differential of the positive most interesting topics in ecology systems is the stability of species. It isa n-species (one-prey, the -dependent predator--prey system with time delay and functional response at the seme time and was inequality constructing suitable Lyapunov functional, a sufficient condition was obtained for the global equilibrium of the system. Finally, the numerical simulation result of population model was given.
