Abstract: Cluster analysis on the spacing pattern and habitat selectionof wolf dens in the prairie of eastern Inner Mongolia is reported. The results are as follows: the main factors affecting the dens distribution are human disturbance and the source of water, others are hiding conditions, slope location, slope degree. The optimal habitats of wolves dens selected on the steep slope (>25°) with hiding conditions over 30%, entrance facing north, human disturbance more than 1 km and source of water less than 1 km.
