摘　　要：森林生境片断化对生活在其中的鸟类产生着难以估量的影响,鸟类的种群动态、种群遗传和局部进化等都不同程度地受环境变化的影响。不同的鸟类对片断化的反应也不尽相同。边缘效应对物种具正负2种效应。片断化对鸟类基因库的影响也随种类而异,它取决于物种遗传变异的数量和性质。鸟类的森林栖息地片断化的反应不仅取决于栖息地及其质量,还取决于其本身所具有的行为的可塑性和内在的遗传变异。Forest fragmentation has immeasurable effects on birds. The population dynamics, population genetics and local evolution of birds are to some extent affected by the changes of environment. Different species of birds respond differently to forest fragmentation. 'Edge effects' have two kinds of effects: negative and opposite. The response of bird to forest fragmentation depends not only on quantity and quality of habitat, but also on plasticity in behavior and its inherent genetic variation.
