摘　　要：1985～1987年,作者在内蒙古乌梁素海地区对大耳猬的生态进行了调查。大耳猬主要栖息在生长有白刺的沙丘上和芨芨草丛下。它们以蜥蜴、蟾蜍、小型啮齿动物、蝼蛄和各种甲虫为主食,也吃锁阳等肉质化植物性食物。其洞系可分为冬眠洞。夏季洞和临时洞三类。一年繁殖一次,平均胎仔数为5.2只。具有冬眠习性,从9月中下旬入蛰,至翌年四月中旬开始出蛰,延续到5月中旬结束。The present paper deals with the ecology of the long-eared hedgehog (Hemiechinus auritus). The studies have been carried out during 1985～1987. The results obtained are summarized as follows. Long-eared hedgehog eat chiefly lizards, toads, small rodents, mole crickets and beetles or various insects, as well as Chinese cynomoriumn etc. fleshy plants. The structure of the burrows is comparatively simple. There are one opening in each burrow, one short tunnel, and one enlarged nest chamber, in which lives only one hedgehog. The long-eared hedgehog breeds one time each year. The average litter size is 5. 2. They hibernate in mid-September and wake up in mid-April of the next year. The period of hibernation is probably 200 days.
