蜂桶寨自然保护区小熊猫巢域初步研究

Home range of red pandas(Ailurus fulgens)in Fengtongzhai Nature Reserve, Sichuan, China

2002年5~11月,在蜂桶寨自然保护区利用无线电遥测技术对6只小熊猫的巢域利用进行了初步研究。结果表明,6只戴颈圈个体M1、M2、M3、F1、F2、F3的巢域面积分别为330·26hm^2、135·18hm^2、190·67hm^2、98·23hm^2、141·60hm^2、204·80hm^2;雄性个体平均巢域面积为218·70hm^2,雌性个体为148·21hm^2。小熊猫个体间巢域重叠普遍,平均重叠率达25·33%,其中雄性个体之间为26·00%,雌性个体之间为23·67%,两性个体之间为25·67%。可能受人为干扰的影响,M1在6只监测个体中巢域面积、日均移动距离均为最大。

Home range is an area where an animal performs its normal living activities. The home-range sizes of six red pandas （Ailurus fulgens） were determined by radio-tracking technique in Fengtongzhai Nature Reserve, Sichuan Province from May to November in 2002. The results indicated that home range sizes of these six pandas, M1, M2, M3, F1, F2 and F3 respectively were 330. 26 ha, 135. 18 ha, 190. 67 ha, 98. 23 ha, 141.60 ha and 204. 80 ha, and the average size was 183.46 ha. Average home-range size for the three males was 218. 70 ha, and for the three females was 148. 21 ha. Males had larger home ranges than did females. Average home-range overlap among these individuals was 25. 33%, and that for males, females and inter-sexualily were respectivly 26%, 23.67% and 25.67%. Perhaps because of human disturbance, home range and average daily movement distance of M1 were the largest among these individuals.
