| 【目的】对黄泥河自然保护区内原麝冬季栖息地的选择策略进行研究，为原麝栖息地保护及其种群恢复提供依据。【方法】2011-11－2012-01，采用机械布点随机设置样线法，调查黄泥河自然保护区内63个原麝利用样方和109个对照样方，首先运用Bailey’s置信区间法分析坡向、坡位、植被类型、石砬子等4个名词型变量；然后运用单样本Kolmogorov-Smimov检验方法及非参数检验中的2个独立样本Mann Whitey U检验，分析海拔、坡度、隐蔽级、郁闭度、灌丛盖度、食物丰富度、距人为干扰距离、雪深、倒木等9个数量型变量，并通过主成分分析法，综合分析了13个因子在原麝冬季栖息地选择中的影响。【结果】Bailey’s置信区间法分析表明，原麝冬季喜欢栖息在有石砬子的阳坡中坡位的针阔混交林中活动；9个数量型变量的原始数据不遵从正态分布（P＞0.05），进一步分析表明，除距人为干扰距离外的其他8个数量型因子在利用样方和对照样方间存在显著差异（P＜0.05），结合置信区间分析结果认为，原麝冬季喜欢在相对海拔、隐蔽级、郁闭度都较高，灌丛盖度较高、坡度陡、雪浅且有倒木、食物丰富的栖息地活动；对这13类生态因子的主成分分析结果与上述分析结果基本一致。【结论】原麝冬季喜欢在相对海拔、隐蔽级、郁闭度都较高，食物丰富、灌丛盖度较高、坡度陡、雪浅且有倒木和石砬子的阳坡中上坡位的针阔混交林中栖息。 |

| Abstract: |
| 【Objective】Selection of winter habitat by musk deer (Moschus moschiferus) in Huangnihe Natuer Reserve was investigated to protect the habitat and recover population of musk deer.【Method】From November 2011 to January 2012,mechanical sampling and random lining method was used to investigate 63 musk deer quadrats and 109 control quadrats in Huangnihe Nature Reserve.First,four nominal variables including slope direction,slope position,forest type,and steep rocky slope were analyzed by Bailey’s confidence interval analysis.Then nine quantitative variables including altitude,slope gradient,sheltering class,canopy,thickets coverage,food abundance,human disturbance,snow depth,and fallen tree were analyzed using single sample Kolmogorov Smimov test.Through principal component analysis,these 13 factors were analyzed comprehensively.【Result】Bailey’s confidence interval analysis indicated that steep rocky slopes,sunny slope,middle slope,and mixed forest were favored by musk deer for habitat selection in winter.Single sample Kolmogorov Smimov tests did not follow normal distribution (P>0.05).Further analysis indicated there were significant differences in eight factors between investgating quadrats and control quadrats (P<0.05).In winter,musk deer liked habitats with high relative elevation,sheltering class,canopy thickets,and coverage,steep slope,light snow and fallen tree,and abundant food.Principal component analysis showed similar results for these 13 ecological factors.【Conclusion】In winter,musk deer preferred mixed forest with high relative elevation,sheltering class and canopy,abundant food,high thickets coverage,steep slope,light snow,fallen tree and steep rocky slopes. |
