Abstract: We documented home ranges for 3 radio-marked (2 ♂,1 ♀)Tibetan foxes (Vulpes ferrilata) in Gouli township, Dulan County,Qinghai Province,China in Sep. 21 - Oct. 21, 2006 and Jan.14 - Jan. 20, Feb. 6 - Feb.12 and Mar.13 - Apr. 8,2007. Home anges of 3 collared Tibetan foxes were quantified using the fixed kernel ethod,and a simple index of home range overlap was also calculated. Mean home range size was 6.4 km² (SE = 0.4)and the mean core area was 1.6 km² (SE = 0.2). Home ranges and core area of all 3 foxes overlapped. Percentage home range overlap was 50% - 60% ,and overlap of core areas was 7% - 20%.

摘要： 2006 年9 月21 日至10 月21 日、2007 年1 月14 ～ 20 日、2 月6 ～ 12 日和3 月13 日至4 月8 日, 应用无线电追踪技术对青海省都兰县沟里乡3 只藏狐(2 雄,1 雌)进行追踪定位,采用Kernel 方法计算了3 只藏狐的家域面积,确定了该物种的核域,并探讨了不同藏狐个体间家域及核域的重叠状况。结果表明,沟里乡藏狐平均家域面积为6.4 ± 0.4 km²,平均核域面积为1.6 ±0.2 km², 核域约占家域总面积的1 /5 ～ 1 /4。3 只藏狐总体家域面积相差不大, 藏狐家域及核域均有一定程度的重叠,家域重叠程度约为50% ～ 60% ,核域重叠程度则远远减小,约为7% ～20% 。
