安西极旱荒漠国家级自然保护区冰洞子沟区域野生动物红外相机监测初报

采用公里网格布设法,在安西极旱荒漠国家级自然保护区冰洞子沟区域设置红外触发相机20部,对区域内大中型兽类和地面活动鸟类进行初步调查。结果显示:监测到兽类4目5科7属7种,鸟类4目7科7属8种,包括北山羊、金雕2种国家Ⅰ级重点保护动物;盘羊、猞猁、狼和短耳鸮4种国家Ⅱ级重点保护动物;兽类中北山羊和中亚兔相对丰富度指数较高,鸟类中石鸡和漠即鸟相对丰富度指数较高。物种稀疏曲线显示,兽类在3个月后趋于稳定,鸟类在10个月后趋于稳定,表明调查取样充分。本次初步调查基本上掌握了保护区冰洞子沟区域鸟兽本底信息,总结讨论了红外相机在鸟兽资源监测中存在的问题及措施,为保护区的科学管理提供地依据和指导。

Preliminary Report on Wildlife Monitoring by Infrared Camera in Bingdongzigou Area of Anxi Extra-arid Desert National Nature Reserve

In order to investigate the status of wild mammals and birds in Bingdongzigou area of Anxi Extra-arid Desert National Nature Reserve,20 infrared trigger cameras were set up by using kilometer grid layout.The results showed that there were 7 wild mammal species belonging to 7 genera,5 families and 4 orders,and 8 wild birds species belonging to 7 genera,7 families and 4 orders,including 2 class I national key protected wild animals,Capra ibex and Aquila chrysaetos,and 4 class II national key protected wild animals,Ovis ammon、Lynx lynx、Canis lupus and Asio flammeus.Capra ibex and Lepus capensis had higher relative abundance index than other mammals,while Alectoris chukar and Oenanthe deserti had higher relative abundance index than other birds.The results of species rarefaction curve showed that mammals tended to be stable after 3 months,and birds tended to be stable after 10 months,which indicated that the survey sampling was sufficient.This preliminary investigation basically grasped the background information of mammals and birds in Bingdongzigou area of the reserve,summarized and discussed the problems and measures of infrared camera in the monitoring of birds and animals resources,and provided basis and guidance for the scientific management of the reserve.
