摘　　要：山溪鲵属(Batrachuperus)是我国特有属,已知6种,除稻城山溪鲵(Batrachuperus daochengensis)外,其余5种全部被列入国家二级重点保护野生动物名录.该属物种主要分布于青藏高原东缘及邻近地区.为了解贡嘎山国家级自然保护区内山溪鲵属动物资源现状,2022年和2023年利用样线法对该保护区内的山溪鲵属动物开展了种群数量和分布调查.在实地调查的44条样线中,有20条样线发现有山溪鲵属动物的分布,占调查样线总数的45.46%,分布于保护区内的康定市、泸定县和石棉县所辖区域;山溪鲵属动物在该保护区内的分布海拔为2 900~4 300 m. 20条样线两年调查共发现成体和幼体250只,卵胶袋17对;在20条样线中,雅家埂泸定方向和虫草基地下两条样线中发现个体数相对较多,其他样线相对较少,部分样线仅发现1只个体.种群数量较大的5条样线2次调查发现的成体和幼体数的差异可能与调查季节有关.最后根据调查结果提出了今后工作的方向和内容.Genus Batrachuperus is a unique genus in China,with 6 known species.except Batrachuperus daochengensis,all the other 5 species were listed in the list of national key protected wildlife in China.The species of genus Batrachuperus are mainly distributed in the eastern margin of Qinghai-Tibet Plateau and adjacent areas.To understand the resources status of salamander in genus Batrachuperus in Gongga Mountain National Nature Reserve,the population distribution and population quantity of salamander in genus Batrachuperus were investigated by line transect method in 2022 and 2023.Among the 44 transect lines,the salamander in genus Batrachuperus were found in 20 transect lines,accounting for 45.46% of the total transect lines,which distributed in Kangding,Luding and Shimian Counties in Gongga Mountain National Nature Reserve.The distribution elevation of salamander in genus Batrachuperus in Gongga Mountain Reserve ranges from 2900 to 4300 m above sea level.A total of 250 adults and juveniles and 17 pairs of egg sacs were found in 20 trans lines during two years.Among the 20 transect lines,a relatively large number of individuals were found in the transect line of Luding direction of Yajiageng and Chongcaojidixia,other transect lines were relatively few,especially only one individual was found in some transect lines.The difference of adult and juvenile numbers found in two surveys of 5 transect lines with large population size may be related to the survey season.Finally,according to the results of the investigation,the direction and content of the future work are proposed.
