Under linear growth condition, we discuss the p-th asymptotic boundedness of the numerical solutions for stochastic age-dependent population system and establish a criterion for the asymptotical boundedness by using Euler-Maruyama (EM) method. Finally, numerical example is presented to demonstrate the accuracy of the conclusion %K 随机种群系统 线性增长条件 Euler-Maruyama方法 p阶矩渐近有界性< %K br> %K stochastic population system linear growth condition Euler-Maruyama method p-th asymptotic boundedness %U http://sxzz.whu.edu.cn/sxzz/ch/reader/view_abstract.aspx?file_no=20180115&flag=1
