摘要
2014和2015年冬季,在大兴安岭图强林业局奋斗林场,利用布设样线的方法对雪兔生境选择进行了研究。通过生境选择指数分析表明,雪兔主要选择在中坡位、阳坡、坡度小于25度、离人为干扰距离大于1000M的针阔混交林和灌丛生境;主成分分析表明,隐蔽条件、食物、温度和人为干扰是影响雪兔生境选择的主要因子。
Winter of 2014 and 2015 in the greater hinggan mountains struggle hard forestry administration forest farm, by using the method of setting sample line of snow rabbit habitat selection is studied. Habitat selection index analysis shows that the snow rabbit main choice in the slope, slope, slope is less than 25 degrees, from human interference distance is greater than 1000 m mixed needle leaf and brush habitats; Principal component analysis showed that the concealed conditions, food, temperature and human disturbance is the main factor affecting the snow rabbit habitat selection.
