扩散是动物生活史中最重要的事件之一，它强烈地影响着种群的动态和分布，对物种内部各种群之间基的因交流、各局部种群的地理适应及分化等均有深远影响，因此对野生动物扩散现象的研究已成为近年来野生动物生态学中的一大热点．在对各类历史研究文献进行综合的基础上，笔者在本文中就食肉动物扩散的模式及进化后果进行了一般性的归纳，并就在大熊猫生态学研究中开展迁移扩散的研究进行了讨论．%Dispersal is one of the key prolesses in the history of animal life, and it not only strongly influences the dynamic condition and distribution of the population, but also affects the gene flow within population, the adoption to environment and diversity of the local population . Hence, the research on the dispersal phenomenon of wild ani- mals in recent years has become one of hot topics in the world animal ecology. On the basis of summing up kinds of literature reviews in the history, we generally conclude the spread of predators mode and evolution consequence, then discuss the research on migration dispersal in giant panda's ecology.
