Abstract: An investigation was conducted in the Maodeng pasture of Xilinhot, Inner Mongolia in May-September 2010 to study the effects of road and grazing on the spatiotemporal variations of the distribution and density of Brandt’s vole (Microtus brandti) population. At the direction vertical to the road and in the phase of lower density (<60 individuals·hm-2), the relative density of the Brandt’s vole population decreased gradually with increasing distance to the road. Grazing made the population density increased. It was suggested that human disturbances such as road-building and grazing activity had effects on the relative density and spatiotemporal distribution of the vole, and the vole itself had definite adaptability to the human disturbances.
