【摘要】 对内蒙古东部草原19个狼的洞穴构造进行了初步研究。结果表明．狼的洞穴构造比较简单。一般只有1个洞口、个别有2个。洞。量度（宽×高）平均为39．5cm×47.9cm.平均洞深为（274.8±48.7）cm。平均洞道长度为（439．3±78．0）cm；卧室宽为（64．5±12．0）cm．85％的洞口朝向大多为阴面．66％的洞穴位于陡坡的上坡和中坡上。更多还原

【Abstract】 The structure of 19 wolf dens in the plain in the east of Inner Mongolia was studied. The results showed that the structure of wolf dens is relatively simple with one entrance generally and few have two entrances. The size means were 39. 5 cm in the entrance width. 49. 5 cm in the entrance height: the depth of den averaged (274. 8±48. 7) cm. The length of tunnel averaged (439. 3±78. 0) cm: the entrance of dens generally faced north (accounting for 85%). The wolf dens were located not only in steep slope (accounting for 66%) but also in the upward slope (accounting for 40%) and middle slope (accounting for 40%).更多还原
