摘要
内蒙古东部草原地区狼洞穴空间分布格局及其生境选择的聚类分析结果表明，影响狼洞穴分布的主要因子为人类活动干扰和水源距离，其次为隐蔽条件、坡位和坡度，狼选择洞穴的最适生境为陡坡，洞口北向，隐蔽条件中等以上。
Cluster analysis on the spacing pattern and habita t selection of wolf dens in the prairie of eastern Inner Mongolia is reported.T h e results are as follows: the main factors affecting the dens distribution are h uman disturbance and the source of water,others are hiding conditions,slope loca tion,slope degree.The optimal habitats of wolves dens selected on the steep slo p e(>25°) with hiding conditions over 30%,entrance facing north, human disturbanc e more than 1 km and source of water less than 1 km.
