摘要
2008年12月,在大兴安岭地区松岭林业局壮志林场对貂熊冬季生境进行了调查,并利用Vanderploeg&Scav-ia选择法进行分析。结果显示:貂熊冬季喜欢栖息在海拔600～800 m,雪深较厚的东向或北向缓坡上,选择在距河流500～1 000 m,郁闭度为40%～60%,隐蔽度30%～50%,乔木密度>80株/100 m^2和倒木数>10株/100 m^2的针阔混交林、针叶林或阔叶林中活动,而要求距铁路和公路距离大于5 km,距居民点距离大于20 km。
We investigated winter habitat selection by wolverines（Gulo gulo） in December 2008 at the Zhuangzhi Forestry Centre of Songling Forestry Bureau in the Great Xing＇an Mountains of northwest Heilongjiang Province,China.We analyzed data using the Vanderploeg Scavia selection index（DATE）.Wolverines preferred mixed broad leaf - coniferous forests with canopy closure of 30%-50%and canopy density of 40%-60%.Forests were located 500 -1 000 m from rivers on hillsides or hill peaks at elevations of 600 -800 m,and supported deep snow accumulations.Tree densities were80/100m^2 and fallen trees numbered10/100 m^2.Preferred sites were farther than 5 km from road or rail corridors,and 20 km from residential areas.
