摘要 2022年3—10月,对贡嘎山国家级自然保护区开展小型兽类专项调查,布设了5条样线48个样方,总计下铗9226铗次,布设陷阱桶1687桶次,布设鼠笼60笼次。共采集标本1299号,经鉴定包含3目6科16属27种。较之以往研究新采集到小型兽类11种。对贡嘎山国家级自然保护区南、北坡小型兽类物种多样性进行了比较,结果表明:(1)贡嘎山国家级自然保护区南坡的小型兽类物种丰富度更高,北坡的小型兽类物种均匀度更高;(2)南、北坡小型兽类优势种有明显差异;(3)不同物种垂直分布区大小存在差异,相同物种在南、北坡垂直分布区大小亦有差异;(4)南、北坡小型兽类物种多样性差异主要体现在啮齿目和兔形目。 From March to October 2022,a special survey of small mammals was carried out in Gongga Mountain National Nature Reserve,and 48 quadrates of 5 sample lines were laid out,with a total of 9,226 forges,1,687 forges of traps and 60 forges of squirrel cages.A total of 1299 specimens were collected and identified,including 3 orders,6 families,16 genera and 27 species.Compared with previous studies,11 species of small mammals were newly collected.The results showed that:(1)The species richness of small mammals on the south slope of Gongga Mountain Nature Reserve was higher,and the species uniformity of small mammals in the north slope was higher;(2)There were obvious differences in the dominant species of small mammals on the north and south slopes;(3)The vertical distribution areas of different species were different,and vertical distribution area of the same species was also different on the south and north slopes;(4)The difference of small mammal species diversity on the south and north slopes was mainly reflected in Rodentia and Lagomorpha.
