摘要:

西藏珠穆朗玛峰国家级自然保护区(以下简称珠峰保护区)是全球海拔最高、相对高差最大的自然保护区, 主要保护世界上独一无二的极高山生态系统、原始的山地森林以及异常丰富的山地生物多样性, 但人类目前对区内两栖爬行动物多样性的研究和了解却十分有限。为了掌握野生动物资源现状, 促进保护区的有效管理, 2010-2012年, 我们先后5次对珠峰保护区两栖爬行动物资源进行了系统的实地调查, 共采集到61号两栖爬行动物标本。结果显示: 保护区至今已记录到两栖动物9种, 隶属1目3科6属; 爬行动物11种, 隶属1目4科10属。区内两栖爬行动物区系组成以东洋界物种占绝对优势, 共有17种, 古北界物种仅3种; 区系特有性明显, 中国特有种2种、主要分布在中国的物种6种。古北界与东洋界在区内的分界明显且没有交汇, 分界线约在海拔3,600-3,800 m之间。我们相信随着实地调查工作的深入, 在保护区南坡沟谷区域的两栖爬行动物物种总数还会有所增加。

Abstract:

The Qomolangma National Nature Reserve (QNNR) in Tibet, China, is the highest nature reserve in the world and is characterized by a wide range in altitude. The QNNR was established to protect its vegetation, unique alpine ecosystem, and overall abundant biodiversity. Amphibians and reptiles are important components of its biodiversity, but are poorly understood. Thus, we surveyed amphibians and reptiles in the QNNR on 5 occasions between October 2010 and October 2012. This survey revealed 9 amphibian species, which belong to 6 genera, 3 families, and 1 order. All of these species belong to the Oriental Realm. We also recorded 11 reptile species belonging to 10 genera, 4 families, and 1 order. Among these species, 8 belong to the Oriental Realm and 3 to the Palearctic Realm. According to our records, the herptofauna of the QNNR is characterized by both endemic amphibian and reptile species with 2 endemic species and 6 quasi-endemic species in China. The estimated species richness of amphibians and reptiles in the reserve is likely to increase with further survey, especially along the southern slope of the Himalayas. A sharp dividing line between the Palearctic region and Oriental region in the QNNR occurs between 3,600-3,800 m a.s.l. with no transition zone.
