Abstract EN
In recent years, the impulsive population systems have been studied by many researchers.
However, seasonal effects on prey are rarely discussed.
Thus, in this paper, the dynamics of the Holling-type IV two-competitive-prey one-predator system with impulsive perturbations and seasonal effects are analyzed using the Floquet theory and comparison techniques.
It is assumed that the impulsive perturbations act in a periodic fashion, the proportional impulses (the chemical controls) for all species and the constant impulse (the biological control) for the predator at different fixed time but, the same period.
In addition, the intrinsic growth rates of prey population are regarded as a periodically varying function of time due to seasonal variations.
Sufficient conditions for the local and global stabilities of the two-prey-free periodic solution are established.
It is proven that the system is permanent under some conditions.
Moreover, sufficient conditions, under which one of the two preys is extinct and the remaining two species are permanent, are also found.
Finally, numerical examples and conclusion are given.
