摘要
讨论一类食饵具常数投放率的捕食者-食饵模型的平衡点性态问题,得到了正平衡点周围极限环的不存在性、存在性与唯一性的充分条件.利用数值模拟验证了所得结论的正确性,并给出了相应结论的生态意义.
The quality of the equilibrium point for a class of predator-prey system with constant rate stocking on prey is discussed.The sufficient conditions for the nonexistence,existence and uniqueness of the limit cycle around the positive equilibrium point are obtained.The results are proved by the technology of numerical simulation.At the same time,the meaning of the ecology is given.
