Gansu zokor (Eospalax cansus) is a small mammal that spends all their lives underground in sealed burrows. To explore the digestive strategies and the regulation in the natural environment, and to understand the plasticity of the digestive tract, the seasonal changes of digestive tract were measured at organ and tissue levels, respectively. The results were as follows: there was not significant seasonal difference between the total length and the gross including contents of digestive tract. Both the fresh and dry weight of the total tracts and various organs were highest in spring, the contents weight were higher in autumn. The organizational structure showed the significant difference in different seasons, the thickness of mucosa, muscular layer and height of intestinal villus were highest in spring. The results indicated that the major factors for Eospalax cansus to adapt to the relatively stable underground environment are the plastic changes and increasing intestinal weights, Incresing the length of digestive organs for its energy is unnecessery.
