高黎贡山北段西坡鸟兽多样性垂直分布特征
Species diversity and vertical distribution characteristics of birds and mammals on the western slope of northern Gaoligong Mountains
摘要
Abstract
The northern section of Gaoligong Mountains is the southern extension of the Qinghai-Tibetan Plateau.Due to its high altitude,complex terrain,and difficulties in replenishment for monitoring teams,wildlife monitoring in this area is particularly weak,especially in high altitude areas.Therefore,it is necessary to conduct a fundamental survey of the bird and mammalian biodiversity in this region,grasp its resource status and spatial distribution law,and adjust its corresponding investigation,monitoring and protection management measures accordingly.From May 2018 to November 2019,using infrared camera technology,an investigation was conducted at different altitudes on the western slope of the northern section of Gaoligong Mountains.A total of 22 mammal species belonging to 13 families and 6 orders,and 43 bird species belonging to 15 families and 4 orders were recorded,including four national first-class protected wild animals,namely,Asian Golden Cat(Catopuma temminckii),Himalayan Takin(Budorcas taxicolor),Dhole(Cuon alpinus)and(Lophophorus sclateri).There were 22 national second-class protected animals such as Gongshan Muntjac(Muntiacus gongshanensis)and Mainland Leopard Cat(Prionailurus bengalensis).The results of relative abundance index showed that the most common mammal in this area was Pallas's Squirrel(Callosciurus erylhraeus),and the most common bird was Blood Pheasant(Ithaginis cruentus).In low-altitude areas,the number of species was higher in spring and winter,whereas in mid-altitude and high-altitude areas,the peak species diversity occured during summer.The Jaccard index calculation results indicated that high-altitude area(3 500-4200 m)had more unique species composition than the mid-altitude area(2700-3 499 m)and low-altitude area(2000-2699 m).Mammalian diversity exhibited a unimodal distribution along the altitudinal gradient,whereas bird diversity appeared the peak at(2 500-3 000 m)and(4000-4200 m)respectively.The following suggestions were proposed:(1)Construction of monitoring trails at high altitude areas to facilitate routine patrols and regular species monitoring;(2)Establishment of monitoring stations to ensure long-term scientific research.关键词
