摘　　要：在内蒙古典型草原区锡林郭勒盟研究了贮草期布氏田鼠（Lasiopodomys brandtii）采食距离及集群数量对采食量的影响。通过人为设置布氏田鼠洞群家族成员数量和采食距离，采用小麦（Triticum aestivum）为采食材料，测定了秋季自由生活状态下，采食距离为5-30 m范围内、每个洞群布氏田鼠数为3-11只范围内，布氏田鼠单次采食量的变化。结果表明，采食距离和家族成员数量对布氏田鼠单次采食量没有明显影响，采食距离和家族成员数量之间也不存在交互作用。布氏田鼠单次搬运麦粒数量平均为8.0粒/次，这可能与田鼠的搬运能力有关。We evaluated the effects of foraging-trip distance and social group sizes on the amount of single trip＇ s food collection of the Brandt’s vole（Lasiopodomys brandtii） during the food storing period in typical steppes in Xilingol League, Inner Mongolia. Wheat（Triticum aestivum） was provided as supplemental food at food stations in different distances to the center of burrow systems to measure the amount of food collection of Brandt’s voles on each single foraging trip. We manipulated the group size of the voles from 3 to 11 individuals, and foraging-trip distance from 5 to 30 meters in this study. The vole can carry about 8.0 wheat seeds on average on each foraging trip. Results show that the amount of food collection of Brandt’s voles was not related to either foraging-trip distances or group sizes. Moreover, there was no direct interaction between foraging-trip distance and group size.
