佛坪自然保护区两栖爬行动物的组成与分布

Composition and Distribution of Amphibians and Reptiles in Foping Nature Reserve

地处秦岭中段南坡的佛坪自然保护区具有丰富的两栖爬行动物资源。当前该保护区分布有16种两栖动物和28种爬行动物,其中的10种两栖类和7种爬行类为中国特有种。分析这些两栖爬行动物的保护状态发现,除大鲵为国家Ⅱ级重点保护的、处于极危状态的物种外,还有11种为处于濒危或易危状态的物种。区内两栖爬行动物的垂直分布特征并不明显,但在海拔1 500m以下的区域分布的种类较多、数量较大。表明佛坪自然保护区是秦岭两栖爬行动物多样性保护的关键区域。针对该区域两栖爬行动物的保护与管理提出了一些建议。

Foping Nature Reserve is located on the southern slope of the middle range of the Qinling Mountains in China,and a rich resource of amphibians and reptiles.Currently,16 amphibians and 28 reptiles occurred in the reserve.Among them,10 amphibians and 7 reptiles belong to the endemic species of China.Giant salamander（Andrias davidianus） belongs to the second-class key species under state-protection,and is a critically endangered species.Besides this species,another 11 species in the reserve are also listed as endangered or vulnerable species in the IUCN Red List of Threatened Species.No obvious characters of ecological distribution along the altitudinal gradient were found for the amphibians and reptiles.However,more species and populations were distributed in the area below 1 500 m a.s.l.Foping Nature Reserve is a key region for the diversity conservation of amphibians and reptiles in the Qinling Mountains.Some suggestions were put forward to protect and manage these species.
