摘  要:
2005年7月和2006年8月,在黑龙江呼中国家级自然保护区,采用机械布点法设置样线,对原麝夏季生境选择进行了研究。Mann-Whitey U检验表明,原麝夏季喜欢活动在乔木密度小、郁闭度低、坡度较陡且隐蔽度高的生境中;卡方检验表明,原麝夏季偏好远离人为干扰的中上坡位、接近碎石坡和水源的阴坡或半阴半阳坡的针阔混交林中;主成分分析表明,前6个特征值的累计贡献率达72.28%,可较好地反映原麝生境特征,因而将原麝夏季生境选择影响因子分别命名为干扰因子、林型因子、坡度因子、水源因子、空间因子和郁闭度因子。

摘  要:
By the method of mechanical transect line, the habitat selection by Moschus moschiferus in summer in Heilongjiang Huzhong National Nature Reserve was studied from July 2005 to August 2006. Mann-Whitey U test showed that M. moschiferus favored the habitats with low tree density, low canopy density, steeper slope gradient, and high sheltering. χ2 test showed that in summer, M. moschiferus preferred to live in the conifer and broadleaf mixed forest at the mid-up slope position far away from human disturbance, close to detritus slope and water source, and of half shady and half sunny. Principal component analysis showed that the first 6 principal components, i.e., human disturbance, forest type, slope location, water source, space, and canopy density, explained 77.28% of all eigenvalues, being able to better reflect the characters of habitat.
