【摘要】 本文利用雪地跟踪方法对哈尔滨西郊5只赤狐在1985—1986年冬季的巢区做了观察。结果表明,5只狐对巢区内各部分使用的强度是不等的,对巢区中部的某些地块使用强度要高于对外围的使用,并具有明显的方向性。5个巢区的平均活动半径为320±68米至557±82米,面积为1.44—4.09平方公里,线性指数为1.079至2。5只狐相邻距离约1000米。更多还原

【Abstract】 Home ranges of five red foxes (Vulpes vulpes) in the west suburbs of Harbin were studied during the winter of 1985-1986 with the snow-tracking method. Results revea-led that activities of five foxes in their home ranges were concentrated near centers with apparent deviation in directions influenced ty man. Mean radii of home ranges were 320 (±68) to 557 (±82)m.,sizes were 1.44 to 4.09 km2 and indices of linearity were 1.079 to 2. Individual distances of five foxes averaged about 1 km.更多还原
