摘要:

本研究以四川王朗国家级自然保护区为研究区域, 利用红外相机对保护区内的主要野生动物进行了初步调查, 分析了该区域的物种多样性现状、相机数量和相机工作日与物种数量间的关系以及物种的相对丰富度。结果表明: 42台红外相机共拍摄到物种独立照片1,793张, 鉴定出野生动物25种, 包括大熊猫(Ailuropoda melanoleuca)、四川羚牛(Budorcas tibetanus)和黄喉雉鹑(Tetraophasis szechenyii) 3种国家一级重点保护野生动物, 黑熊(Ursus thibetanus)、黄喉貂(Martes flavigula)、中华鬣羚(Capricornis milneedwardsii)、中华斑羚(Naemorhedus griseus)等8种国家二级重点保护野生动物。在相机数量增加到23台的时候拍摄到了本次记录的全部25种野生动物, 并且在单台相机工作日达到180天时, 物种数达到饱和。保护区内物种相对丰富度最高的是血雉(Ithaginis cruentus)(29.28)和毛冠鹿(Elaphodus cephalophus)(15.78); 大熊猫的相对丰富度为8.09; 红腹角雉(Tragopan temminckii)、中华鬣羚和黄喉雉鹑的相对丰富度在2-5之间; 中华斑羚、勺鸡(Pucrasia macrolopha)、黑熊、四川羚牛和蓝马鸡(Crossoptilon auritum)的相对丰富度最低, 不到1。综上所述, 红外相机能够有效地对野生动物资源进行监测调查, 对于相对丰富度较低的物种需要投入更多的精力, 这些物种的栖息地保护对于自然保护区的发展至关重要。

Abstract:

We used infrared camera to monitor wild animals in Wanglang National Nature Reserve. Our goal was to estimate species diversity, the relationship between the number of cameras and number of species, the relationship between the camera days and number of species, and the relative abundance of species. Across 42 locations, we recorded a total of 1,793 images in which we found 25 species of wildlife. Species found in our camera traps included three national first-class protected species such as giant panda (Ailuropoda melanoleuca), Sichuan takin (Budorcas tibetanus) and buff-throated partridge (Tetraophasis szechenyii). We also recorded eight national second-class protected wild animals such as the Asiatic black bear (Ursus thibetanus), yellow-throated marten (Martes flavigula), Chinese serow (Capricornis milneedwardsii), Chinese goral (Naemorhedus griseus). These 25 species were captured when we increased the number of trap-days increased to 23 or any single the trap was placed for at least 180 days. Furthermore the blood pheasant (Ithaginis cruentus) (29.28) and the tufted deer (Elaphodus cephalophus) (15.78) had the highest relative abundances in the reserve. The relative abundance index for the giant panda was 8.09 and the indices for temminck’s tragopan (Tragopan temminckii), Chinese serow and buff-throated partridge was between 2 and 5. The Chinese goral, koklass pheasant (Pucrasia macrolopha), Asiatic black bear, Sichuan takin and blue eared-pheasant (Crossoptilon auritum) had the lowest relative abundance values (all < 1). In summary, we found camera-trapping to be an effective method for wildlife survey. Our findings suggest that less abundant species need more camera trapping effort. Nature reserves are important for protecting habitats of endangered species.
