摘要
2008年6～7月,在广西岑王老山国家级自然保护区采用样带法对再引入黑颈长尾雉(Syrmaticus humiae)的栖息地选择进行了研究。共测定了7条样带上的22个栖息地样方和17个对照样方的24个生态因子。结果表明,再引入黑颈长尾雉的夏季栖息地偏向于选择海拔低、坡位低、乔木较低和灌木较高、落叶盖度较大、灌木层盖度大、草本高且盖度大的阔叶林、针阔混交林或者针叶林;逐步判别分析的结果显示坡位、草本层盖度是重要的生态因子,由这两个变量构成的方程在对栖息地和对照区进行区分时,正判率可以达到77.3%,这种选择与黑颈长尾雉的隐蔽条件和食物密切相关。
Habitat selection of the Reintroduced Mrs Hume＇s Pheasant （ Syrmaticus humiae） was studied from June to July 2008 in Cenwanglaoshan Nature Reserve. Total of 22 sites used by the pheasant were located in 7 transects crossing the whole study area. Twenty-four ecological factors associated with those used sites and 17 random plots were examined in the study area. The results showed that habitats were characterized by low altitude,low slope location,low average height of arbor,high herbs,large cover of deciduous leaf,large cover of shrub and grasses. The classification showed that the slope and herb cover were important factors. The overall classification model constructed from those two variables was successful to distinguish the habitats from random ones at the precision of 77. 3% . Summer habitat selection of the Mrs Hume＇s Pheasant was mainly related to food and concealment.
