摘要
1998年 3月～ 1999年 2月在四川省青川县唐家河自然保护区 ,对鬣羚 (Capricornissumatraensis)春冬季的生境利用进行了研究。结果表明 :影响鬣羚春季生境选择的主要生态因子为人为干扰、植被型、乔木距离、乔木密度、坡度、岩石距离、乔木大小和坡位 ;影响其冬季生境选择的主要生态因子为人为干扰、植被型、坡位、郁闭度、水源、乔木距离、乔木密度、乔木大小、灌木大小、岩石距离、坡向、动物干扰度 ;鬣羚春冬季对生境的选择分离主要表现为坡度、海拔、乔木大小、乔木距离、灌木距离、岩石距离、坡位、植被型、郁闭度。
Habitat selection of mainland serow ( Capricornis sumatraensis ) was studied in Tangjiahe Natural Reserve,Qingchuan County of Sichuan Province from March 1998 to February 1999.The results showed as follows:The main ecological factors notably influenced on habitat selection of mainland serow in spring were human disturbance,vegetation type,tree dispersion,tree density,slope,rock dispersion,tree size and slope position.The main ecological factors notably influenced on habitat selection of mainland serow in winter were human disturbance,vegetation type,slope position,canopy,water source,tree dispersion,tree density,tree size,shrub size,rock dispersion,slope aspect and animal dispersion.The separation of habitat selection of mainland serow in spring and winter showed mainly in the ecological factors,slope,elevation,tree size,tree dispersion,shrub dispersion,rock dispersion,vegetation type,slope position,canopy and water source.
