2004年7 - 10月，在青海省郭洛大武地区对高原鼠兔的贮藏行为进行了研究。采用放置法、样方取样法和横断面法获得了原生植物种类的计数。结果表明：高原鼠兔在生长季节贮藏干草堆，以备冬季取食。高原鼠兔选择的植物种类反映了其栖息地植被。高原鼠兔收集的植物被放在叶子宽大的植物上，防止草堆腐烂。挖掘结果表明，高原鼠兔有在洞中储存食物的习惯。
We studied caching behavior in the plateau pika Ochotona curzoniae in the Dawu, Guo Luo, Qinghai Province from July to October of 2004 when caching behaviour occurs. Counts of cradaled plant species were obtained using placement, quadrat sampling, and transection methods. The results showed that in the growing season plateau pika cached hay-piles for feeding in the winter. Plant species chosen by the plateau pika reflected their habitat vegetation. Plants collected by plateau pika were placed on plants with spacious leaves to prevent the hay-piles from rotting. The results of excavation indicated that plateau pika habitually store food in holes.
