摘要: 大鲵(Andrias davidianus)为我国特有的珍稀两栖动物,已列入国家二级保护动物名录,并列入CITES公约附录I中。自20世纪50年代起,由于过度收购、非法捕杀和栖息地丧失等原因,大鲵种群数量下降极为严重,湖南、安徽等地的大鲵产量在20世纪50年代至70年代下降超过80%,分布区也极度萎缩,形成了12块岛屿状区域,目前分布于以我国中部山区的长江流域为主的17个省区。部分已建立的大鲵保护区经费短缺,人员不足,管理不力,状况不容乐观。非法捕捉和栖息地丧失仍是威胁大鲵生存的主要因素,保护管理力度还需进一步加强。

AbstractChinese giant salamander ( Andrias davidianus ) is an endangered amphibian in China. The species is currently listed in annex I of CITES and in class II of the national list of protected animals in China, even though its status is not clear. Chinese giant salamander has declined steeply in both distribution range and population number since the 1950s because of excessive hunting for commercial trade and loss of habitat. The quantity of purchase of Chinese giant salamander in Hunan and Anhui Province declined over 80% from 1950s to 1970s. The salamander survives now in 17 provinces of China, mainly in the mountainous areas of the middle Yangtze River. Illegal hunting in the wild and loss of habitats are still major threats to Chinese giant salamander survival in some established reserves. The problems of these reserves are lack of funds and personnel, as well as ineffective management. We make some recommendations for conservation management of the Chinese giant salamander.
