摘要
四川九寨沟国家级自然保护区地处岷山中部,拥有丰富的野生动物资源与较高的生物物种多样性。2019年11月至2021年12月,使用红外相机技术在九寨沟保护区开展鸟兽多样性调查,共布设红外相机调查位点106个,覆盖海拔范围为2189~3514 m,总有效工作量76342相机日。野生兽类、鸟类的独立有效探测数分别为11045次和648次,共记录到分属5目13科的野生兽类25种,其中国家重点保护野生动物14种(一级4种,二级10种),种群相对多度最高的为毛冠鹿(Elaphodus cephalophus,相对多度指数RAI=48.66);记录到分属4目10科的鸟类33种,其中国家重点保护野生动物13种(一级3种,二级10种),种群相对多度最高的为血雉(Ithaginis cruentus,RAI=2.33)。偶蹄目和鸡形目分别是红外相机记录到兽类和鸟类中的优势类群,分别占兽类和鸟类独立有效探测总数的84.92%和64.50%。调查中记录到九寨沟保护区新记录种7个,包括藏酋猴(Macaca thibetana)、亚洲狗獾(Meles leucurus)、小麂(Muntiacus reevesi)、水鹿(Rusa unicolor)、梅花鹿(Cervus nippon)5种兽类和四川淡背地鸫(Zoothera griseiceps)、乌鸫(Turdus mandarinus)2种鸟类。相比于保护区之前的2次红外相机调查,本次调查的工作量和覆盖范围均大大增加,记录到的鸟兽物种数量也有明显增长,调查结果为九寨沟保护区的生物多样性编目和物种名录更新提供了可靠数据,为保护区系统建立野生动物监测体系、有效开展保护管理提供了基础。
Jiuzhaigou National Nature Reserve,Sichuan Province,locates in central Minshan Mountains and harbors a rich fauna with high species diversity.From November 2019 to December 2021,we conducted a camera-trapping survey in Jiuzhaigou reserve to investigate its terrestrial mammals and birds.With an extensive sampling effort of 76342 camera-days at 106 camera stations which spans across a broad elevation range from 2189-3514 m,we recorded 25 wild mammal species(belonging to 13 families and 5 orders)with 11045 independent detections and 33 bird species(belonging to 10 families and 4 orders)with 648 independent detections.Among these species,14 mammal species(4 as Class Ⅰ and 10 as Class Ⅱ)and 13 bird species(3 as Class Ⅰ and 10 as Class Ⅱ)are listed as China’s key protected wildlife species.Tufted deer(Elaphodus cephalophus,RAI=48.66)and blood pheasant(Ithaginis cruentus,RAI=2.33)are the most detected mammal and bird species,respectively.Artiodactyla and Galliformes are the dominant mammal and bird group in the community,whose independent detections account for 84.92% and 64.50%,respectively,of all mammal and bird detections.Seven species,including five mammals,i.e.,Tibetan macaque(Macaca thibetana),Asian badger(Meles leucurus),Reeves’muntjac(Muntiacus reevesi),sambar(Rusa unicolor)and sika deer(Cervus nippon),and two birds,i.e.,Sichuan thrush(Zoothera griseiceps)and Chinese blackbird(Turdus mandarinus),are recorded for the first time in Jiuzhaigou.Compared to the two previous camera-trapping surveys in Jiuzhaigou,this study covered much broader areas with higher sampling efforts and recorded more species in the reserve.These results will provide reliable data base for the biodiversity inventory and species list updating of Jiuzhaigou,and will serve as the foundation for the reserve to establish a systematic wildlife monitoring system and carry out future conservation and management actions.
