摘要
根据2020年5月—2021年6月对四川米亚罗自然保护区的实地调查,结合红外相机监测数据和文献资料,统计出兽类7目23科86种。其中国家一级重点保护野生动物9种,国家二级重点保护野生动物17种,中国特有种27种。IUCN红色名录评估为濒危(EN)、易危(VU)和近危(NT)的分别为4种、8种和9种。红外相机记录的25种大中型兽类中,相对多度指数最高的是猕猴Macaca mulatta(14.47),其次是中华鬣羚Capricornis milneedwardsii(8.92)、猪獾Arctonyx collaris(5.66)和黄喉貂Martes flavigula(3.56)。在采集的24种小型兽类标本中,以北社鼠Niviventer confucianus、中华姬鼠Apodemus draco、针毛鼠Niviventer fulvescens和小纹背鼩鼱Sorex bedfordiae为优势种。物种丰富度在海拔3000~3500 m最高,共记录33种;2000~2500 m最低,仅10种。保护区的珍稀濒危物种多,有蹄类丰富,但捕食性兽类种类及多度较低,高山区放牧严重。保护区需要进一步加强监测,特别是对高山区的监测,同时控制放牧强度,以进一步了解保护区的兽类资源及提升保护成效。
From May 2020 to June 2021,field survey was conducted in the Miyaluo National Nature Reserve,Sichuan.Combined with the infrared camera monitoring data and historical data,a total of 86 mammalian species belonging to 23 families and 7 orders within the reserve were recorded.Specifically,there are 9 species ranked as classⅠnationally key protected species in China and 17 species ranked as classⅡ,and 27 species are endemic to China.Moreover,4 are evaluated as EN,8 as VU,and 9 as NT by the IUCN Red List.Among the 25 large and medium-sized mammal species recorded by infrared cameras,Macaca mulatta had the highest relative abundance index(14.47),followed by Capricornis milneedwardsii(8.92),Arctonyx collaris(5.66)and Martes flavigula(3.56).Of the 24 small mammal species,the dominant species were Niviventer confucianus,Apodemus draco,Niviventer fulvescens and Sorex bedfordiae.The highest species richness(33 species)was detected at the elevation ranged from 3000 m to 3500 m,while the lowest species richness(10 species)was detected at the elevation ranged from 2000 m to 2500 m.There are many rare and endangered species and abundant ungulates species in the reserve,but fewer number and abundance of predatory mammals.Given that the grazing activities in high mountain areas are intensive,the reserve needs to strengthen the routine observation and limit the grazing intensity for more effective conservation of animal resources in the reserve.
