湖北神农架国家级自然保护区两栖爬行动物物种多样性

对神农架自然保护区两栖爬行动物进行调查,整理了神农架自然保护区两栖爬行动物名录共71种,新发现湖北省新分布种6种,其中腾格里蛙Rana tenggerensis Zhao,Macey et Papenfuss、宁陕小头蛇 Oligodon ningshaanensis Yuan离原分布区较远,神农架新分布种3种,神农架两栖爬行动物的区系特征以东洋界(74.69%)为主,广布种(18.31%)、古北界(7%)种类次之,体现了南北混杂的特点.随着海拔的升高,两栖爬行动物生物多样性总体呈下降趋势,400～1600 m两栖爬行动物生物多样性最高,随海拔下降的趋势不明显,1900 m以上多样性急剧下降.
