So far, amphibian chytridiomycosis has led to regional extinction of nearly 200 kinds of amphibians and reduced 50% of amphibian populations in the world. In recent years, amphibian chytridiomycosis occurs frequently in Europe. For instance, amphibian chytridiomycosis cases have been found successively in Spain, Germany and Italy, especially in Germany. Currently, with the development of prosperous world trade, the spread of chytrid fungus through trade between countries has posed a huge poten- tial threat to the ecological security of amphibians in China. [ Method] According to entry-exit inspection and quarantine standards of the people＇s Republic of China, in this paper, release assessment, contact exposure assessment and consequence assessment technologies were integrated to obtain the risk assessment result of chytrid fungus from Europe and the possibility assessment result of the colonization and dissemination of chytrid fungus after the introduction. [ Result] The risk assessment result of chytrid fungus from Europe to China was identified as ＂moderate＂, and the possibility assessment result of the colonization and dissemination of chytrid fungus after the introduction was identified as ＂high＂. [ Conclusion] The importation of amphibians from Europe to China exhibits a certain risk. The intro- duction of chytrid fungus in China will cause a high risk of colonization and dissemination.展开更多
