摘　　要：采用无线电遥测法在中国科学院海北高寒草甸生态系统定位站对高原鼢鼠的挖掘行为及其与土壤硬度的关系进行了研究。结果表明 ,在相同的硬度条件下 ,雌雄动物的挖掘行为格局和挖掘效率基本相同 ,但是雄性动物挖掘所持续的时间明显高于雌性动物。随着土壤硬度的增加 ,高原鼢鼠挖掘的时间及每次挖掘时持续的时间明显增加 ,而每次的掘土量显著减少。野外调查也表明土壤硬度是影响高原鼢鼠对栖息地选择的一个重要因素 ,高原鼢鼠明显选择土壤硬度较小、而杂草类生物量较高的地方栖息。Burrowing behaviors of the plateau zokors (Myospalax bailely) in relation to soil hardness were investigated by using radio-telemetry at Haibei Alpine Meadow Ecosystem Research Station, Qinghai, China. The results showed that there were no differences of burrowing behaviors and the efficiencies of the excavating segment between male and female, except the digging duration of the male w as longer than that of the female in the same soil. With increase of soil hardness, digging duration in incisors significantly increased, but dried soil mass dug out by the zokors in each bout reduced. Meanwhile the field investigation als o showed that soil hardness affected the distribution of the zokor.
