摘要:
建立了一个具有毒素脉冲输入和干扰的非自治随机模型.通过构造比较系统，利用微分方程的比较定理等方法，证明了系统的均值有界性和全局吸引性，确定了系统非平均持续生存和平均持续生存的充分条件，进而研究了系统的一些动力学行为.
Abstract:
A nonautonomous stochastic population model with pulse input of environment toxin and random perturbation was proposed.By constructing comparison systems and utilizing comparison theorem of differential equation,the boundedness of expectation and global attractivity of the system were proved.The sufficient condition of non-persistence in the mean and persistence in the mean were established.Furthermore,some dynamic behaviors of the system were investigated.
