| Summary: | In the world today, with the rapid development of modern agriculture and industry, a large quantity
of pollutants enter into ecosystems one by one, which is a threat to the persistence of the
exposed populations. This paper investigates a stochastic delayed competitive system with impulsive
toxicant input in a polluted environment. Under a simple condition, sufficient and necessary
conditions for stability in the mean and extinction of each species are established. Some
recent works are improved and extended greatly. Some numerical simulations are also included
to illustrate and support the findings. |
