Abstract: Total 6 sets of badgers (Meles meles) were investigated and measured in Yancheng Nature Reserve. The results showed that the average numbers of entrances of the set are 12.7 and average set size is 192.1 m². 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 asionally. The badger is very sensitive animal; it will dig new holes when the entrance was disturbed.

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192.1 m²。洞径的平均大小为25.8 (±8.1)×32.3(±1.8) 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5.3% , 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, 另掘新洞口。
