摘要
在蚜虫种群折叠突变模型的基础上,本文考虑到作物种群对蚜虫种群的影响作用,建立麦蚜种群广义系统模型.利用广义系统稳定性理论,得到其各平衡点稳定的充分条件.最后通过数值模拟验证结论的正确性.
Consider the influence of crop population on the wheat aphid populations, a singular system model of wheat aphid populations is build up based on the model with fold catastrophe. Using the stability theory of singular systems, the corresponding sufl：ieient conditions are give. Finally, numerical simulations are carried out to prove the results.
