１９８９－１９９２年冬季，作者在大兴安岭林区调查２５６９ｋｍ样线，遇见５７条貂熊足迹链和５个洞穴，研究了貂熊的冬季活动特征和卧息习性。结果表明，在２５ｃｍ雪深时，貂熊足迹印大小平均长宽为８×２５ｃｍ，印深５．５ｃｍ，步距２８ｃｍ，左右步宽２４ｃｍ；每昼夜活动距离为１４．０３±２．８７ｋｍ。据此推算貂熊在大兴安岭冬季活动范围可达２６２－４２２ｋｍ￣２，其活动路线主要有捕食、游荡和拾渣等各种类型。貂熊多夜间活动，白天卧息，行走时很少休息。卧息地分为临时休息地、睡卧地和洞穴３种。洞穴最大可达２．５×１．８×０．８ｍ￣３。
In the winter of 1989-1992, the author investigated 2569km samples in the forest of Daxinganling, met 57 beetle footprint chains and 5 caves, and studied the winter activities and habitat of the bears. The results showed that at a depth of 25cm, the mean size of the footprint of the bears’ bear footprints was 8 × 25cm, the depth of imprinting was 5.5cm, the step distance was 28cm, the step width was about 24cm, and the distance between day and night was 14.03 ± 2.87km. According to this calculation, the winter wilderness area of Daxinganling can reach 262-422km ~ 2. The main routes for its movement are predation, wandering and picking up slag. Sogota bear activities at night, rest during the day, rarely resting when walking. Rest is divided into temporary rest, sleeping and caves 3 species. Cave up to 2.5 × 1.8 × 0.8m ~ 3.
