摘　　要：为了厘清白水河自然保护区的小型兽类区系及多样性调查,2020年4—9月利用铗日法和陷阱法对白水河自然保护区的小型兽类开展了调查,涵盖了8个海拔段共10个调查样方,海拔跨度为1400 m到3350 m,共采集到小型兽类26种。参考本项目组采集历史记录和发表的文献资料,确定白水河自然保护区小型兽类共计44种,分属4个目,13科;其中,啮齿目最多,有23种;食虫目其次,有12种;翼手目、兔形目各5种。通过生物多样性指数计算,Margalef指数和Shannon-Weiner指数表明1400 m海拔段物种多样性最低,Simpson指数显示3550 m海拔段物种多样性最低,物种均匀度指数表明1500 m海拔段物种相对密度最不均匀,1800 m海拔段物种分布个体数最为均匀。本研究结论可为白水河自然保护区小型兽类物种多样性研究和生物保护起到理论和数据支持。In order to investigate the fauna and diversity of small mammals in Baishuihe National Nature Reserve Nature Reserve,a survey of small mammals was conducted by snap traps and pitfall traps from April to September 2020.The survey covered 10 survey quadrats at 8 elevation sections,spanning from 1400 m to 3350 m altitude,and 26 species of small mammals were collected.According to the historical records and published literatures published by the project team,a total of 44 species of small mammals belonging to 4 orders and 13 families were identified in Baishuihe National Nature Reserve.Among them,there were 23 species of Rodentia,12 species of Insectivora,5 species of Chiroptera and 5 species of Lagomorpha.According to the calculation of biodiversity index,Margalef index and Shannon-Weiner index showed the lowest species diversity at 1400 m altitude,Simpson index showed the lowest species diversity at 3550 m altitude,species evenness index showed that the relative density of species at 1500 m was the most uneven,and the number of individuals at 1800 m was the most uniform.The conclusion of this study could provide theoretical and data support for species diversity research and biological protection of small mammals in Baishuihe National Nature Reserve.
