摘　　要：根据Bak-Sneppen模型的特点,从五个方面分析了它的研究进展,尤其是对各种情况下模型表现出的自组织临界性给出了详细的论述;分析了该模型在复杂性理论研究中的地位;最后,还对该模型的未来研究工作做了评述.Bak-Sneppen model is an extremal dynamical model, which plays an important role in the study of selforganized criticality. According to the features of the model, we review the rescarch advances in five aspects, especially on the self-organized criticality of the model in various circumstances. We also discuss the importance of the model in the study of complexity theory, and make comments on possible future works of the model.
