四川扭角羚春冬季对栖息地的利用初步研究

1998年3月至1999年2月，在四川省青川县唐家河自然保护区，对四川扭角羚（Budorcas taxicolor tibetana)春冬季对栖息地的利用进行了初步研究。结果表明，影响四川扭角羚春季栖息地利用的主要生态因子为人为干扰，植被型、乔木大小、乔木距离，乔木密度、食物丰富度，海拔，坡位、郁闭度，影响冬季栖息地利用的主要生态因子为人为干扰。植被型，乔木距离，灌木大小，灌木密度，动物干扰度，乔木大小、灌木距离，坡位，郁闭度，水源，四川扭角羚春冬季栖息地利用的分离主要表现为食物丰富度，乔木大小，乔木密度，乔木距离，植被型，水源，坡位等生存因子的分离。

A Preliminary Study on Habitat Use of Sichuan Takin in Spring and Winter

Habitat use of Sichuan Takin(Budorcas taxicolor tibetana)in spring and winter was studied in Tangjiahe Natural Reserve, in Qingchuan county, Sichuan Province from March 1998 to February 1999.The results showed as follows: The main ecological factors notably influenced on habitat use of Sichuan Takin in spring were human disturbance, vegetation type, tree size, tree density, tree dispersion, food abundance, elevation, slope position and canopy. The main ecological factors notably influenced on habitat use of Sichuan Takin in winter were human disturbance, vegetation type, tree dispersion, shrub size, shrub density, animal disturbance, tree size, shrub dispersion, slope position, canopy and water source. The diference of habitat use of Sichuan Takin between spring and winter showed mainly in food abundance, tree size, tree density, tree dispersion, vegetation type, water source and slope position.
