摘　　要：大鲵是我国珍贵稀有的物种资源,具有广泛的社会经济生态价值。目前在世界上,只有美国、日本和中国有分布,并且这3个地区的大鲵在形态上有一定的差异。大鲵是我国两栖物种中特有的濒危物种之一,其可以作为生物多样性、生物进化、性别决定分子机制等问题的研究材料。近年来,野生大鲵在自然界中的数量急剧下降,为了保护和人工养殖的要求,人们对它的研究力度不断加大,著述颇多。文章对近期大鲵在生物学方面的研究资料进行了整理与回顾,并简要探讨了大鲵今后主要的研究工作,以期为后续学者提供参考。Chinese giant salamander(Andrias davidianus)is an endangered amphibian in China.It has a great economic and ecosystem value.And now in the world there are three kinds of giant salamander,locating in China,America and Japanrespectively,and they has a fow differences in some aspects.Nowadays,Chinese giant salamander has declined steeply in both distribution range and population number since 1950s,because of excessive hunting for commercial trade and loss of habitat that lead many people do lots of research on it.The giant salamander in biology research data were collected and reviewed in recent years,the main research work of giant salamander was also discussed briefly,to provide reference for the further research of schdars.
