摘　　要：复杂系统研究是当前的热点,脆性是复杂系统的一个基本属性.在一个复杂系统中,当一个子系统遭受足够大的打击而崩溃时,整个系统将会崩溃.元胞自动机是一个离散的动力学系统,它可以用来仿真复杂系统的行为.文章应用元胞自动机对复杂社会系统的脆性进行仿真.仿真结果说明传染病扩散对其它社会子系统具有很大的影响.作为复杂系统的一个子系统,传染病的大规模扩散会使社会混乱,进而得出它具有脆性的结论.Now the research on complex system is a hot spot. Brittleness is one of the basic characteristics of complex system. In complex system, after an enough power strikes one of subsystems, which leads to its collapse, the whole system will be collapsed. The cellular automata is a discrete dynamic system which can simulate the action of a complex system. With cellular automata, the simulation of the complex society system' brittleness is built. The result of simulation proves that the diffusion of an infectious disease has a great influence on another society subsystem. As a society subsystem, the large-scale diffusion of the disease can make the society chaos, and it possesses brittleness.
