摘　　要：什么是信息?在这个信息爆炸时代,尤其是理解复杂系统的涌现行为时,信息熵有什么作用?为了回答和理解这些问题,我们讨论了信息熵的起源,信息熵与热力学熵的区别,信息熵对复杂性理论(包括混沌理论和分形理论)的作用,并推测了信息熵可能会起重要作用的新领域。What is information?What role does information entropy play in this information exploding age,especially in understanding emergent behaviors of complex systems?To answer these questions,we discuss the origin of information entropy,the difference between information entropy and thermodynamic entropy,the role of information entropy in complexity theories,including chaos theory and fractal theory,and speculate new fields in which information entropy may play important roles.

关 键 词：信息熵 热力学熵 涌现 混沌 分形 复杂性理论 多尺度分析
