[Objectives] Habitat is the basis of wild animals, and bed-sites is one of the most important functional patches. In order to understand the bed-sites habitat characteristics and selective utilization pattern of wild Alpine Musk Deer, this study was conducted from December 2021 to January 2022, in Xinglongshan National Nature Reserve of Gansu Province in northwestern China. [Methods] We obtained the bed-sites records of Alpine Musk Deer by sample line survey method. Vanderploeg selection coefficients and Scavia selection indices were used to calculate the selection of discrete variables, and principal component analysis and resource selection function were used to assess the bed-sites habitat selection. [Results] The results showed that wild Alpine Musk Deer preferred to use habitats with lower altitude (2 488.5 ± 26.6 m), higher shrub height (1.3 ± 0.3 m), higher shrub canopy (31.08% ± 3.14%), higher ground-plant cover (38.36% ± 3.27%), more fallen wood (0.5 ± 0.1) plot and shallower snow cover (1.0 ± 0.3 cm) in winter (Table 1); and preferred to use habitats in southern lower slope, closer to water resources, shrub habitats with good concealment condition in winter (Table 2); the principal component analysis showed that the cumulative contribution of arbor factor, food factor, safety factor and topographical factor amounted to 67% (Table 5). The resource selection function yielded a log-linear model: Logit(x) =﹣4.967 + 0.001 × altitude﹣0.02 × slope gradient + 0.03 × arbor canopy + 0.104 × arbor height + 0.17 × shrub canopy﹣0.466 × snow depth﹣1.015 × slope aspect (Table 7). [Conclusion] Our results reflected the comprehensive ecological demands of security, food and water resources adaptability of bed-sites used by Alpine Musk Deer during winter.
