西藏墨脱县小型兽类多样性研究

Biodiversity of Small Mammals in Medg County,Tibet of China

墨脱县位于我国西藏东南部,雅鲁藏布江下游,交通极为不便。县域最南部海拔不到500 m,最高峰是南迦巴瓦主峰,海拔7 782 m。生态系统原始,植被垂直带谱完整,雨量充沛,生物多样性丰富。2008年和2011年,我们两次对墨脱县的小型兽类(食虫类、翼手类、啮齿类和鼠兔类)进行了调查,结合资料,确认墨脱县有小型兽类4目7科31种。东洋界种类占绝对优势,喜马拉雅-横断山系分布型为最多的分布类型。

Medog area is located in southwestern Tibet and lower Yarlung Zangbo River. Its transportation is extremely inconvenient. The southern altitude of this county is less than 500 metres and its highest mountain is the Nanjagbarwa Feng with the elevation of 7 782 metres. Medog county has a very aboriginal ecosystem, very plentiful rainfall and abundant vegetation and biodiversities. Small mammals （insectivores ,bats ,rodents and pikas） were surveyed in 2008 and 2011. Combined with references ,31 species of small mammals were confirmed, belonging to 4 orders and 7 families. Most of small mammals belonged to Oriental realm species.
