Computational Simulation on The Model of Three Species System Under Pulse Input of Toxin in a Polluted Environment

摘要：

In this paper,based on the Mdel of three species Volterra system under the effects of contin-uous discharge of environmental toxin,we established and considered the model of persistence and extinc-tion for the three species system with the in put of impulsive toxin in a polluted environment. Researches on the dynamical behavior of the model enable us to obtain the key factors for determining the existence and extinguishments of each species by using computa-tional simulation;Researches also enable us to obtain in theory,the conditions for each species to continue to live.By simulating,a unique positive periodic so-lution that is globally asymptotically stable in the sys-tem model is found.
