摘要
有尾类是两栖动物三大类群中一个重要而特殊的类群,其四肢较弱,运动能力不强,分布地域性明显,开展有尾类分布现状和受危状况研究,对探讨有尾类动物系统进化和促进资源保护均具有重要的意义。作者通过广泛查阅国内外重要文献发现,中国有尾目现已记录50种及3亚种,隶属于3科15属,其中有中国特有种42种及3亚种,占中国有尾类物种总数的84.9%。对中国有尾类特有种的区系组成、分布特点、保护现状和受危状况进行了分析,并探讨了有尾类特有种的分布特征;针对有尾类种群数量下降的原因,提出了相应的保护对策。
Urodela are an important category of the three main types of living amphibians. Their limbs and locomotor ca- pacity are not strong, and their distributions are within certain regionalism, so it is helpful to understand animal phylogenet- ics that studying their distributions and threatened status. According to the domestic and foreign literature, there are 50 spe- cies and 3 subspecies of Urodela in China, belonging to 3 families and 15 genera. Among which, there are 42 species and 3 subspecies endemic to China that accounted for 84.9% of the total number of Chinese Urodela species. The distribution, protection status, threatened factors, and the composition characteristics of those endemic species are analyzed. At last, some protective measures against the decline of Urodela population are suggested.
