摘　　要：东北鼢鼠的堵洞行为,是其适应地下生活的一种行为反应。通常认为是其避光怕风的生态习性促使其产生堵洞行为,但相关的实验证据较为缺乏。为验证这一观点的正确性以及为进一步探究其堵洞行为产生的机理提供科学依据,本研究于2014年8月在内蒙古呼伦贝尔草甸草原进行了野外试验。试验采用2×2列联表设计,将风、光因子组合为4个处理,分别为风光都进入洞道、风进入洞道光不进入洞道、风不进入洞道光进入洞道、风光都不进入洞道。并通过自行设计的专利"风光隔离器"使每个处理达到了试验的要求。试验随机选取68只东北鼢鼠作为试验样本,并将样本平均分配到4个处理中进行试验,对堵洞与否进行记录。通过Shannon信息量互信息法、卡方独立性检验分别对风、光因子的独立性、风光单因子与堵洞行为的关系进行了分析。结果表明:就堵洞而言,风光因子是独立的,不存在交互作用(I=7.22×10^(-5));风、光单因子与东北鼢鼠的堵洞次数差异不显著(P﹥0.05)。野外试验表明,东北鼢鼠的堵洞行为与风和光无关。Burrow-sealing behavior of Transbaikal zokor（ Myospalax psilurus） is considered as a adaption to long-term underground living. Some research suggests that sealing-behavior was caused by the zokors＇ fear of wind and light. However this view lacked empirical evidence. A study using a 2 × 2 contingency-table design including 2 factors and 4 treatments was conducted in August,2014 in a Hulunbuir pasture,Inner Mongolia to examine the burrow-sealing behavior of zokor.Sixty eight zokors were randomly divided into 4 groups,and each group was subjected to 1 treatment. Data of sealing-burrow behavior was recorded and analyzed using mutual information analysis of Shannon information and chi-square test. The results show that（ 1） combination of wind with light did not affect sealing behavior of Transbaikal zokor（ I = 7. 22 ×10^-5）;（ 2） both wind and light had no significant influence on Transbaikal zokor sealing behavior（ P ﹥ 0. 05）. These results indicated that sealing behavior of Transbaikal zokor did not correlated with wind and light.
