摘要
1998年 3～ 4月和 1999年 1～ 2月 ,作者在四川省青川县唐家河自然保护区 ,应用主成分分析和判别分析的方法 ,对斑羚 (Naemorhedusgoral)春冬季对生境的利用进行了研究。研究结果表明 :影响斑羚春季生境选择的主要生态因子为人为干扰度、植被型、坡位、郁闭度、水源、乔木距离、乔木大小、灌木距离、坡度、灌木大小 ;影响其冬季生境选择的主要生态因子为人为干扰度、植被型、坡位、郁闭度、坡向、海拔、灌木大小、坡度、食物丰富度、乔木密度 ;斑羚春冬季生境选择的分离主要表现为植被型、郁闭度、水源、坡位、坡度、乔木大小、乔木距离、灌木密度等生态因子的分离。
Habitat selection of Long tailed Goral (Naemorhedus goral ) was studied by using the main factors analysis and the discriminant functional analysis in TangJiahe Natural Reserve, Qingchuan county of Sichuan province from March to April 1998 and from January to February 1999.The results showed as follows: The main ecological factors notably influenced on habitat selection of Long tailed Goral in spring were human disturbance, vegetation type, slope, canopy, water source, tree dispersion, tree size, shrub dispersion, slope, shrub size and animal disturbance. The main ecological factors notably influenced on habitat selection of Long tailed Goral in winter were human disturbance, vegetation type, slope position, canopy, slope aspect, elevation, shrub size, slope, food abundance, tree density and tree dispersion. The separation of habitat selection of Long tailed goral in spring and winter showed mainly in the ecological factors, slope, tree size, tree density, shrub density, vegetation type, slope position, canopy and water source.
