Abstract: The studies of amphibian population ecology are far less deep and extensive than those of mammals and birds.This paper mainly deals with summarizing the amphibian population structure and dynamic disciplinarian,behavior of taking food and foods analysis,call analysis and communication,process and habit of reproduce,preparation and adaptation for hibernation,and amphibian decline of the worldwide.A lot of reports stated had been reported both in the domestic and the abroad.Through the summary,the authors try to expatiate upon the research status in quo and existing problems among different studies,then to analyze what areas should be studied more and where may be developing trends in the future.As the environment worsen and survival space decreased,populations of all amphibian species are faced with tremendous survival pressure,and may be extinct in someday indeed.Thus,it is important to explore the relationship between the amphibian and the external circumstances through research on the amphibian population ecology widely and deeply,which will have many realistic and theoretic values for the environment inspection and for the protection and utilization of the amphibian population.
