食物囤积是许多物种在食物短缺时期生存的关键适应。社鼠（Niviventorconfucianus）广泛分布于我国温带地区，但其食物贮藏行为尚不清楚。在北京市门头沟区东灵山地区（40°00′N，115°30′E），以野生山杏（Prunus armeniaca）种子和辽东栎（Quercus liaotungensis）橡子为食物源，在长×宽×高= 4× 3× 1 m的围隔内，对白腹鼠的食物贮藏行为进行了研究。结果表明：（1）中国白腹鼠在储藏室中囤积食物;（2）模拟偷窃储藏食物刺激大鼠囤积更多的食物;（3）中国白腹鼠选择野杏种子进行囤积，并在短期内消耗更多的辽东栎橡子。我们讨论了可能的影响因素，在这个物种的食物囤积行为。
Food hoarding is a key adaptation for many species to survive periods of food shortage. The Chinese white-bellied rat(Niviventor confucianus) is widely distributed in the temperate zone in China, but food hoarding behavior of this species is almost unknown. We investigated food hoarding behavior of white-bellied rats by providing them with wild apricot(Prunus armeniaca)seeds and Liaodong oak(Quercus liaotungensis)acorns within enclosures(L ×W ×H = 4× 3× 1 m)in the Dongling Mountains (40°00′N, 115°30′E), Mentougou District, Beijing. We found that 1)Chinese white-bellied rats hoarded food in larders, 2)simulated pilfering of stored food stimulated rats to hoard more food items, and 3)Chinese white-bellied rats selected wild apricot seeds for hoarding, and consumed more Liaodong oak acorns in the short term. We discuss possible factors influencing food hoarding behavior in this species.
