摘要
基于国家重大工程川藏线建设需求,为降低道路建设和运营对野生动物的影响,于 2019 年 6 月—2021 年6 月通过红外相机技术对拟建川藏铁路沿线(康定至巴塘段)6 种有蹄类动物的活动节律进行了研究.结果表明:1)毛冠鹿(Elaphodus cephalophus)在6 种有蹄类动物中相对丰富度最高,其次为中华鬣羚(Capricornis milneed-wardsii),水鹿(Rusa unicolor),野猪(Sus scrofa),马麝(Moschus chrysogaster),中华斑羚(Naemorhedus griseus).2)毛冠鹿与中华鬣羚的年活动格局具有较高的相似度,1-4 月相对丰富度为全年最低,5-6 月逐渐上升,7 月达到全年最高峰,之后逐渐降低.3)毛冠鹿和马麝的日活动规律相似,均属双峰型,具明显晨昏习性;野猪和水鹿日活动模式呈单峰型,水鹿活动曲线呈U形,午间出现低谷,属于特殊的单峰模式;中华鬣羚和中华斑羚活动规律不明显.4)毛冠鹿和野猪在旱季和雨季的日活动节律具有明显的分化.5)水鹿和马麝是典型的夜行性动物,毛冠鹿和野猪是典型的昼行性动物,中华鬣羚和中华斑羚不具有明显的昼夜行性.
Abstract
Based on the construction needs of the Sichuan-Tibet Line,a major national project,in order to reduce the impact of road construction and operation on wildlife and protect biodiversity,from June 2019 to June 2021,the activity rhythms of 6 ungulates along the proposed Sichuan-Tibet Railway(Kangding to Batang section)was studied by using infrared camera technology.The results show that:1)Elaphodus cephalophus has the highest relative abundance among the six ungulate species,followed by Capricornis milneedwardsii,Rusa unicolor,Sus scrofa,Moschus chrysogaster and Naemorhedus gri-seus.2)The annual activity patterns of Elaphodus cephalophus and Capricornis milneedwardsii gazelle exhibit a high degree of similarity.The relative abundance is lowest from January to April,gradually in-creasing from May to June,reaching its peak in July,and then gradually decreasing afterwards.3)The diurnal activity patterns of Elaphodus cephalophus and Moschus chrysogaster are similar,both belonging to bimodal type,with obvious dawn and dusk habits;The daily activity patterns of Sus scrofa and Rusa unicolor are unimodal,and the activity curve of Rusa unicolor is U-shaped,and the trough appears at noon,which belongs to the special unimodal pattern.The activity regularity of Capricornis milneedward-sii and Naemorhedus griseus is not obvious.4)The diurnal activity rhythm of Elaphodus cephalophus and Sus scrofa in the dry season and the rainy season is significantly differentiated.5)Rusa unicolor and Moschus chrysogaster are typical nocturnal animals,Elaphodus cephalophus and Sus scrofa are typi-cal diurnal animals,and Naemorhedus griseus and Capricornis milneedwardsii do not have obvious diur-nal movement.
