摘要
2022 年 5 月至 2023 年 3 月,在广东新丰云髻山省级自然保护区布设 80 台红外相机,累计获得 20 705 个相机工作日,获得独立有效照片 14 881 张,共记录到鸟兽 63 种,隶属 12 目 29 科.物种相对多度指数中,排前 5 位的兽类依次为鼬獾、小麂、野猪、花面狸和倭花鼠;排前 5 位的鸟类依次为白鹇、紫啸鸫、虎斑地鸫、灰胸竹鸡和灰背鸫.月活动节律分析结果与其他文献调查结果基本一致.在不同海拔段、生境类型下兽类物种数及相对多度指数均存在差异不显著;不同海拔段鸟类物种数及相对多度指数存在差异显著,不同生境类型下鸟类物种数存在差异不显著、相对多度指数存在差异显著.调查结果为云髻山自然保护区后续的保护管理和动态监测提供了可靠的数据支持和指导.
Abstract
From May 2022 to March 2023,80 infrared camera traps with a total working day of 20,705 were set up in the Yunji Mountain Provincial Nature Reserve in Xinfeng County,Guangdong.A total of 14,881 inde-pendent photos were collected,from which 63 wild bird and mammal species belonging to 12 orders and 29 families were identified.For the index of relative abundance,the top five mammal species were Melogale moschata,Muntiacus reevesi,Sus scrofa,Paguma larvata,and Tamiops maritimus,and the top five bird species were Lophura nycthemera,Myophonus caeruleus,Zoothera aurea,Bambusicola thoracicus,and Tur-dus hortulorum.The monthly activity rhythm analysis results were consistent with those from other literature.There were no significant differences in the number and relative abundance index of mammal species across different altitudes and habitat types.In terms of bird species,the number and the relative abundance index were significantly divergent at different altitudes,while at different habitat types,only the relative abundance index showed a significant difference.The results provided reliable data support and guidance in the Yunji Mountain Nature Reserve for biodiversity management and long-term dynamic monitoring.
