摘　　要：多态现象对了解物种的遗传、变异和进化有着重要意义,鸟类羽色多态现象的进化机制,是多态现象研究中非常重要的内容。鸟类羽色多态现象的进化机制假说主要有:分化选择假说、异类选择假说和非随机性交配假说等。本文对鸟类羽色多态现象的概念和以上进化机制假说进行了综述,并针对鸟类羽色多态现象进化机制研究中存在争议的问题及研究的不足提出了自己的看法。Polymorphism is meaningful in understanding the heredity, variation and evolution of species. The evolutionary mechanism of avian color polymorphism is one of the important parts in polymorphism research. Several main hypotheses have been put forward to explain the evolutionary mechanism of color polymorphism in birds, including disruptive selection hypothesis and apostatic selection hypothesis and nonrandom mating hypothesis etc. All kinds of hypothesis on evolutionay mechanism of color polymorphism in birds are summarizd and a general review about the controversies and absences of existent references are also presented in the paper.
