摘要
雅鲁藏布江加查峡谷内栖息着种类丰富的野生动物,国家一级重点保护野生动物——喜马拉雅鬣羚(Cap-ricornis thar)也生活在峡谷内,但一直未见喜马拉雅鬣羚的系统调查研究,而影响对喜马拉雅鬣羚的科学保护.因此,为了促进加查峡谷后续开展科学、有效地保护和管理工作,2020 年5 月到 2022 年 12 月,在加查峡谷内共布设85 台红外相机对喜马拉雅鬣羚进行监测,并且对喜马拉雅鬣羚的活动节律进行初步研究.相机总工作天数39 109 d,其中80 台相机拍摄到喜马拉雅鬣羚,共获得有效照片 15 744 张,其中独立有效探测照片数 2 650张.研究结果:1)喜马拉雅鬣羚全年的日活动节律呈现双峰型,活动高峰出现在4∶00-6∶00 和19∶00-21∶00,活动低谷出现在10∶00-15∶00;2)四季对比发现秋季的活动强度比春、夏、冬季高;3)旱季的活动高峰比雨季 的活动高峰提前1h,并持续更长的时间;4)喜马拉雅鬣羚为夜行性动物.使用红外相机对加查峡谷进行了近两年半的监测,对峡谷喜马拉雅鬣羚的活动节律有了一定了解,为后续的研究、保护以及管理打下基础.
Abstract
Jiacha Gorge of Yarlung Zangbo River is home to a rich variety of wild animals,a national priority protected wild animal Himalayan iguana(Capricornis thar)also lives in the gorge,but there has been no systematic investigation of the Himalayan iguana,which affects the scientific protection of the Himalayan iguana.From May 2020 to December 2022,a total of 85 infrared cameras were deployed in Jiacha Gorge to monitor the Himalayan iguana and conduct preliminary studies on the activity rhythm of the Himalayan iguana.The total working days of the cameras were 39109 days,of which 80 cameras captured the Himalayan iguana antelope,obtaining a total of 15744 effective photos,of which 2650 in-dependent effective detection numbers.The results showed that:1)the daily activity rhythm of the Hi-malayan iguana presented a bimodal pattern throughout the year,with the peak of activity occurring at 4∶00-6∶00 and 19∶00-21∶00,and the trough at 10∶00-15∶00;2)The activity intensity in autumn was higher than that in spring,summer and winter;3)The activity peak of the dry season is one hour earlier than that of the rainy season,and lasts longer;4)Himalayan iguanas are nocturnal animals.The infrared camera has been used to monitor the Jiacha Gorge for nearly two and a half years,and the ac-tivity rhythm of the Himalayan iguana in the gorge has been understood to a certain extent,which lays a foundation for subsequent research,protection and management.
