摘要
本文对苏北盐城保护区６个狗獾洞巢进行了初步研究。结果表明：每个洞巢平均有１２．７个洞口组成，占地面积平均为１９２．１ｍ２。洞径的平均大小为２５．８（±８．１）×３２．３（±１１．８）ｃｍ。洞道口可分为斜向型、垂直型和水平型，分别占总洞口的７７．６％、１１．８％和１０．５％。每个洞巢动物经常用来进出的洞口２～３个，占总洞口数的１９．７％，废弃的洞口占总数的５５．３％，另有２５％洞口偶而使用。狗獾极其敏感，一旦常用洞口有异物即放弃使用。
Total 6 sets of badgers (Meles meles) were investigated and measured in Yancheng Nature Reserve. The results showed that the average number of entrances of the set are 12 7 and average set size is 192 1 m 2. The average diameter of entrance is 25 8(±8 1)× 32 2(±11 8) cm. The entrances can be divided into three types: inclined entrance; vertical entrance; and horizontal entrance. The persentage of three types entrances are 77 6 %, 11 8 % and 10 5 %, respectively. Only two or three entrances are frequently used per set (19 7 %), 55 3 % of the entrances were abandoned and 25 % of the entrances were used occasionally. The badger is very sensitive animal, it will dig new holes when the entrance was disturbed.
