长青国家级自然保护区大中型兽类及雉类垂直分布特征

The Vertical Distribution and Abundance of Large and Medium-sized Mammals and Pheasants in Shaanxi Changqing National Nature Reserve

为给保护区制定科学、合理、经济的保护措施提供参考和依据,2008年3月至2012年6月,利用被动式红外触发相机陷阱调查技术,并以300 m海拔为间隔,调查研究了陕西长青国家级自然保护区大中型兽类(食肉目动物和偶蹄目动物)和雉类(鸡形目动物)的种类及其多度和分布,结果为在共调查的393个有效相机监测位点和14431个有效相机工作日中,记录到本保护区有大中型兽类16种、雉类4种,其中国家一级、二级重点保护动物分别有5种和10种;优势动物食肉目是大熊猫、黑熊,偶蹄目是羚牛、中华斑羚、野猪,鸡形目是红腹角雉;海拔1500~2500 m范围,物种相对多度更大,保护地位更重要。

For supporting better regional conservation strategy development,the distribution of large and medium-sized mammals and pheasants in the region was investigated.The relative abundance index(RAI)of targeted species was piecewise calculated per 300 meters from high elevation to low elevation.16 species of large and medium-sized mammals and 4 species of pheasant had been captured by 393 effective camera monitoring sites with 14,431 effective camera workdays from March 2008 to June 2012,including 5 species of fist class and 10 species of second class of national protected animals.Among these species,giant panda is the dominant species of carnivora(average RAI=10.03),takin is the dominant species of artiodactyla(average RAI=155.68),and temminck's tragopan is the dominant species of pheasant(average RAI=3.45).The RAI of large and medium-sized mammals and pheasants is higher in the elevation range between 1,500 m to 2,500 m,thus the conservation efficiency of this region is critical for protecting large and medium-sized mammals and pheasants in the research area.
