Abstract: In winters (October~December) from 1991 to 1993, we conducted a research on home ranges of 7 wild sables (4 males, 3 females) with radio collars in Daxingan ling Mountains, Northeast China. Research results indicated that average home range size of males was 13.03km2 (9.13~17.33 km2) , that of females was 7.18km2 (6.13~8.42km2 ). Males had almost two times larger homeranges than that of females. The longest diameter of homeranges of male sables was 5.50 km , that of females was 4.17 km.There was over-lap of homeranges between male and female. Average degree of over-lap was 62.0%. Over-laps of homeranges hardly existed among male individuals. Factors affecting homerange size mainly were sable exes, abundance of foods , human disturbance and so on.

摘要: 1991至1993年10~12月的三个冬季中, 借助无线电遥测技术对7只紫貂(4雄, 3雌) 活动范围进行了研究。结果表明雄性紫貂的活动范围为13.03 km2, 雌性为7.18 km2, 雄性的几乎为雌性的2倍。活动范围多为长条形, 且多与山脉走向相一致。雄性活动范围的最大距离为5.50km , 雌性为4.17 km。雌雄个体间的活动范围有部分重叠现象, 重叠程度为62.0%。雄性个体间几乎无重叠现象。影响活动范围大小的因素主要为动物体型大小、食物丰富度和人为干扰等。
