摘　　要：2008年9月至2009年8月,在黑龙江省方正林业局新风林场,用不定宽样线法对藏獾洞穴生境选择进行研究,共记录了55组藏獾洞穴,藏獾洞口平均直径为(27.40±7.15)cm,洞深平均为(84.18±22.04)cm,倾角平均为(26.36±9.10)°,洞口总数=3.02个常用洞数+0.80个不常用洞数+0.56个废弃洞数。相对于对照样方而言,藏獾洞穴更偏爱选择位于郁闭度和植被盖度小,灌木密度大、距离近,乔木距离远,距水源和农田近、人为干扰距离远,坡度较缓的向阳中坡位的生境。资源选择函数模型为:logit(p)=246.980-1.059×植被盖度-0.703×距水源距离-1.403×坡度-45.005×坡向,模型的正确预测率为93.9%。The sett plays an important role in the badger habitat selection for providing a shelter to resist adverse weather, escape predators, and reproduce. In the context of rapid transformation of agriculture lands to forest plantations and increasing human development activities, understanding the badger sett habitat selection is requisite to conserve badger habitats. Nevertheless, the Asian badger sett habitat selection has rarely been studied in China. From September 2008 to August 2009, we used six randomly selected 8 km line-transects that covers the entire study area to investigate the sett habitat of Asian badger （ Meles leucurus） in Xinfeng Forest Farm of Fangzheng Forestry Bureau, Heilongjiang Province, China. We established a plot of 10 × 10 square meters that centers at each of the detected setts and measured 18 variables of the sett habitat （vegetation type, elevation, dominant tree species, tree density, tree height, average diameter at breast height of the nearest tree, distance to the nearest tree, canopy closure, shrub density, shrub height, distance to the nearest shrub, herbage coverage, distance to water resource, distance to cropland, distance to human disturbance, slope, aspect, and slope position）. It was found from a total of 55 badger setts that the average size, depth, and obliquity of setts were （27.40±14.30） cm, （84.18±44.07） cm, and （26.36±18.2） degree, respectively. We also used equal number of plots of 10 × 10 square meters （i.e. 55） as controls to collect the same variables of the sett habitat, which were randomly established 500 m away from the detected setts in a random direction. In this paper, the Kolmogorov Smiruov test was used to assess the normality of 14 numerical sett habitat variables. The two-tailed t-test and Mann-Whitey U test were used to compare the sett habitat variables measured from both the sett and control plots. The results reveal that the Asian badger prefers the setts with lower canopy closure and herbage coverage, and higher shrub dens
