Abstract: Dispersal is one of the hottest fields in ecological research,while dispersal ecology has become a new discipline in biological sciences.This paper reviewed some basically theoretical problems about dispersal ecology,such as the definitions of dispersal,research scopes and its relationships with other disciplines in biology,and the significance of dispersal was also summerized.The research scopes of dispersal ecology are very wide and covers from microbes to vertebrates,involving not only ecological theories (e.g.metapopulation,diversity,complex and stability of community and ecosystem) and evolutionary theories (e.g.speciation),but also the application for species protection,biodiversity conservation,pest control (inclusive invading species),epidemic prevention,environmental protection,and demographic management.It is essential to study dispersal for the biological theories and practical problems.
