红外相机技术目前已成为调查监测大中型兽类和地面活动鸟类的一种常规手段,在自然保护区物种资源编目中具有重要的应用价值.在2014年10月至12月间,我们采用红外相机技术在云南哀牢山国家级自然保护区北部布设了40个相机位点,布设密度为1台/2 hm2,对中山湿性常绿阔叶林野生鸟兽进行了初步调查.相机累计工作1 961个有效工作日,共获得野生动物独立有效照片566张,鉴定出隶属4目9科的10种兽类和2目4科的10种鸟类.相对丰富度指数较高的前2种兽类和3种鸟类分别为红颊长吻松鼠 (Dremomys rufigenis) 、野猪 (Sus scrofa) 和白鹇 (Lophura nycthemera) 、长尾地鸫 (Zoothera dixoni) 及斑背燕尾 (Enicurus maculatus) .属于国家Ⅱ级重点保护野生动物的有4种,被IUCN红色名录评估为"易危 VU"级别的物种有2种,列入CITES附录Ⅱ和Ⅲ的物种分别有2种和3种.本次调查仍有多种重要大中型兽类和鸟类未被记录,但是为保护区后续的野生动物红外相机常规监测和保护管理提供了基础信息.%Camera-trapping has been considered as an important method for monitoring large and medium-size mammals and terrestrial birds,and with high applied value to biological inventory for protected areas. From October to December 2014,we set up 40 infrared camera monitoring sites (1 camera for each two hactera) in the northern part of Ailaoshan National Nature Reserve,Yunnan Province,to monitor wild mammals and birds in mid-mountain humid evergreen broadleaved forest. During the total 1 961 camera days,we identified 10 mammals species and 10 bird species from 566 independent images. According to the relative abundance index (RAI),Asian red-cheeked squirrel (Dremomys rufigenis) and wild boar (Sus scrofa) were ranked as two most abundant mammals,while silver pheasant (Lophura nycthemera) 、longtailed thrush (Zoothera dixoni) and spotted forktail (Enicurus maculatus) were ranked as the three most abundant bird species. Among the twenty wild mammal and bird species,four species were categorized as class Ⅱ state key protected wild animals,two species were listed by the IUCN global red list as Vulnerable,two and three species were classified as Appendix Ⅱ and Ⅲby CITES,respectively. Although several key territorial mammal and bird species were not recorded, this preliminary research still provides basic information of biodiversity for establishing camera-trapping routine survey and conservation management of the natural reserve.
