摘  要:
本文采用数量化分析方法 ,对呼伦贝尔草原黄羊春季采食生境选择进行了研究。研究发现 ,影响呼伦贝尔草原黄羊春季采食生境选择的主要因子是放牧家畜干扰、水源、人为干扰 ,其次是坡度、坡位、坡向、植被类型、食物丰盛度 ,风向也有一定影响。其采食生境选择的倾向性依次为 :放牧家畜干扰距离 >2 0 0 0m ,水源距离≤ 10 0 0m ,坡度 5~ 2 5° ,人为干扰距离 >10 0 0m ,坡位在中坡 ,植被类型是针茅或针茅 +羊草群落 ,食物丰盛度中等以上 ,阳坡或半阴半阳坡

摘  要:
Spring foraging habitat selection by Mongolian Gazelle (Procapra gutturosa) in Hulun-Beir grassland was studied with cluster analysis. Based on the analyses,It was concluded: The main factors that influence spring foraging habitat selection by Mongolian Gazelle were herding animals disturbance, water sources,human disturbance;The secondary factors were slope degree, slope position, slope aspect, vegetation type, food abundance; wind direction had a little influence on spring foraging habitat selection by Mongolian Gazelle. The optimal spring foraging habitat of Mongolian Gazelle were as follows: distance to herding animals disturbance>2 000 m; distance to water sources≤1 000 m; slope degree 5~25°; distance to human disturbance> 1 000 m; middle slope; Stipa spp. or Stipa spp. and Aneurolepidium chinese; excellent or fair food abundance; Sunny slope or half sunny and half shady.
