摘要
2019-2021年通过红外相机陷阱法对四川贡嘎山国家级自然保护区九龙片区进行了大中型兽类监测.共布设相机90台(正常工作71台),累计完成14 495个相机工作日,获得大中型兽类独立有效照片1 926张.共记录到大中型兽类4目12科20种;包括国家一级重点保护野生动物林麝Moschus berezovskii,以及13种国家二级重点保护野生动物.此外,在该地区首次记录到赤麂Muntiacus vaginalis.相对多度指数(RAI)居前3的为毛冠鹿Elapho-dus cephalophus(RAI=8.058)、中华鬣羚Capricornis milneedwardsii(RAI=1.352)和岩羊Pseudois nayaur(RAI=1.338).共有33台相机记录到以放牧和采集为主的人为活动,表明该地区人为干扰较为严重.本研究结果可为该区域大中型兽类物种多样性编目及保护区的管理提供基础数据.
Abstract
As an indispensable part of ecosystem,species diversity and population size of large and medium-sized mam-mals are important indicators to reflect the quality of ecological environment.From 2019 to 2021,camera-trapping was used to monitor the large and medium-sized mammals in the Jiulong area of Gongga Mountain National Nature Reserve(Sichuan Province,China).A total of 90 cameras were set up with 71 cameras in normal operation,and 1 926 indepen-dent and effective photos of large and medium-sized mammals were obtained during the 14 495 camera working days.In to-tal,20 species of large and medium-sized mammals belonging to 4 orders and 12 families were recorded.In addition to the class Ⅰ nationally key protected wild animal,forest musk deer(Moschus berezovskii),there were 13 class Ⅱ nationally key protected wild animals.Notably,the red muntjac(Muntiacus vaginalis)was newly recorded in the area.The top three large and medium-sized mammal species with high relative abundance index(RAI)were tufted deer(Elaphodus cephalo-phus)(RAI=8.058),Chinese serow(Capricornis milneedwardsii)(RAI=1.352)and blue sheep(Pseudois nayaur)(RAI= 1.338).Furthermore,33 cameras recorded human activity,mainly grazing and gathering,indicating a high level of hu-man disturbance in the area.This study can provide a scientific basis for the inventory of large and medium-sized mammal species diversity and the management of protected areas in this region.
