摘　　要：为了更好地控制鼠害,对海拉尔东山达乌尔黄鼠洞穴周围的植物、海拔、土壤、洞口朝向等生境因子进行调查,研究发现,在生物环境因子的选择中,达乌尔黄鼠偏好选择生长着冷蒿、黄蒿或糙隐子草的灌木丛和草丛的环境,洞穴的洞口朝向以西北和东北为主。结果表明达乌尔黄鼠对生境的选择是基于保存自身能量、获取食物和躲避天敌的基础上的。In order to control rodent better, an investigation was made on bio-environmental factors including vegetation, height, soil and mouth direction of a cave round caves of Citellus dauricus. The result showed that, C. dauricus preferred to the brushwood or grass growing with Artemisiafrigida, A. scoparia, Cleistogenes squarrosa, and the mouth of caves mainly directed toward the northwest and northeast. A conclusion was drawn that habitat selection of C. dauricus was aimed at saving their own energy, accessing to food and avoiding their natural enemies.
