摘　　要：本文对有限空间年龄结构种群模型提出了一种新的数值方法,通过将标准的间断Galerkin有限元法与流线扩散有限元法相结合,建立了一个稳定的间断有限元格式,并讨论了格式解的收敛性。In this paper, a numerical method is considered for an age--structured population model with space--limited recruitmen. The method is constructed by making use of the difference discrete method for time variables and the discontinuous streamline diffusion method for space variables. The convergence in proper norm is established for the considered scheme.
